The second generation of the Porsche Cayenne was launched at the 2010 Geneva Motor Show.
It was a big improvement over its predecessor and featured an evolved design.
The first generation of the Cayenne brought as many fans as enemies to the German Porsche brand, but the fact was that it became the most sold vehicle from the brand’s stable. Not only that the SUV trend was good for business, but it also offered true performances and comfort. It was the absolute Porsche for the entire family.
The second generation came with a lighter bodywork and new styling for the front, that resembled the Panamera. The hood was similar to the 4-door Porsche sedan as well. The big debate about the car was in the rear, where the taillights were somehow similar in the design concept with those from a Hyundai SantaFe.
Inside, the Panamera inspiration was obvious. A new steering wheel, instrument cluster, and buttons layout on the center console was installed. The center stack was redesigned as well and the vents were taller than the VW-like air-vents from its predecessor. The sunroof was standard for the S version.
For the engine, the Cayenne S featured a 4.8-liter V8 unit 100 hp stronger than the base, 3.6-liter version taken from the VW lineup, and 100 hp less than the 500 hp Cayenne Turbo. For the transmission, the 2010 Cayenne lost the low-range transfer case. The standard transmission was an 8-speed Tiptronic gearbox. All-wheel drive was installed standard as well.
More dynamic and more efficient, more spacious inside and lighter overall, pointing into the future of technology and in sporting, elegant design – the new Cayenne is more Porsche than ever before.
Led by the Porsche Cayenne S Hybrid, the first production car from Porsche with hybrid drive, the new generation of models paves the way in terms of modern efficiency, with a reduction in fuel consumption by up to 23 per cent versus the former models.
Like every Porsche, the new Cayenne has been developed according to the principle of Porsche Intelligent Performance: more power on less fuel, greater efficiency and lower CO2 emissions.
Given these facts and figures, three out of five models in the range remain below the limit of ten litres fuel consumption per 100 kilometres in the New European Driving Cycle. Two models – the Cayenne Diesel at 195 g/km and the Cayenne S Hybrid at 193 g/km – also remain below the emission limit of 200 grams of CO2 per kilometre.
This significant reduction of fuel consumption throughout the entire range of Porsche Cayenne models results, among other things, from the introduction of Porsche’s new eight-speed Tiptronic S automatic transmission complete with Auto Start Stop and an even wider range of gear increments, thermal management on the engine and transmission cooling circuit, recupera tion of the on-board network, variable overrun cut-off and, not least, consistent reduction of weight and intelligent lightweight construction.
Benefiting from a weight-optimised mix of materials and concept changes on the overall vehicle such as the new, extra-light all-wheel drive, weight is down on the Porsche Cayenne Turbo, to mention just one example, by no less than 185 kilos or almost 410 lb, despite the improvement in product substance and an even higher standard of all-round safety. Clearly, this is good news not only in terms of fuel consumption and CO2 emissions, but also when it comes to performance, agility and handling on the road.
As a result, the new Porsche Cayenne offers even more driving pleasure than before both onroad and offroad, combined with even greater everyday driving qualities, enhanced comfort and supreme elegance. Brand-new, sporting but elegant design makes the new generation of the Cayenne in 2010 an even closer member of the Porsche family, bringing out its particular character as a sporting performer even more from every angle and clearly re-vealing that particular shape and design so typical of a Porsche.
World Premiere of the Porsche Cayenne with Parallel Full Hybrid
Presenting the Cayenne S Hybrid, Porsche is proudly introducing the Company’s first hybrid drive vehicle in the market. Developing this trendsetting system, Porsche’s engineers are following in the footsteps of no lesser than Ferdinand Porsche himself, who created the Lohner-Porsche Semper Vivus way back in the year 1900. To this day, the Semper Vivus is acknowledged as the first functional full hybrid in the world.
The Porsche Cayenne S Hybrid is driven primarily by a supercharged three-litre V6 with direct gasoline injection developing maximum output of 333 hp. This modern power unit interacts with an electric motor delivering 34 kW (47 hp) output and peak torque of 300 Nm (221 lb) maintained consistently up to a speed of 1,150 rpm.
The electric motor is able to drive the Porsche Cayenne by itself or support the combustion engine, while also serving as a generator and starter. Together with the separator clutch, it forms the hybrid module positioned between the combustion engine and the new eight-speed automatic transmission.
A further essential component of the hybrid system is the 288-V nickel metal-hydride (NiMh) battery beneath the floor of the luggage compartment, serving to save electrical energy generated when applying the brakes and re-gained while driving.
Using a six-cylinder engine, the Porsche Cayenne S Hybrid offers the power and performance of an eight-cylinder on much lower fuel consumption. With its overall output of 380 hp, the new Cayenne S Hybrid consumes just 8.2 ltr/100 km (equal to 34.5 mpg imp) in the New European Driving Cycle and limits CO2 emissions to a mere 193 g/km. This makes the new Cayenne S Hybrid not only the cleanest Cayenne with the lowest level of CO2, but rather the cleanest Porsche throughout the brand’s entire portfolio.
Specific hybrid driving conditions
The Porsche Cayenne S Hybrid offers the following driving conditions, together with many other qualities:
Driving on electric power alone: In this case the electric motor drives the vehicle all by itself without any support from the combustion engine. With the driver opting for a moderate style of motoring – for example in residential areas – the Cayenne S Hybrid is able to cover short distances with zero emissions and minimum noise up to a speed of 60 km/h or 37 mph.
Boosting: In this case the Cayenne S Hybrid is powered by the combustion engine and the electric motor together. The joint power of both drive units ensures optimum acceleration, for example when overtaking.
Shifting the load point: The combustion engine drives the vehicle by itself, at the same time charging the traction battery through the electric motor acting as a generator. The power used by the generator constitutes a further load on the combustion engine, which is therefore able to operate at a more favourable load point with higher efficiency.
Recuperation: The kinetic energy of the vehicle is converted into electrical energy when applying the brakes, and the battery is charged in the process.
Sailing: Whenever the driver takes back the gas pedal at a speed of up to 156 km/h or 97 mph the combustion engine is switched off and detached to avoid any drag forces from the engine.
Auto Start Stop: The combustion engine is automatically switched off at a standstill, for example with the traffic lights on red or in a traffic jam.
Compact and light parallel full hybrid
Porsche uses a parallel full hybrid instead of the usual split hybrid to be found otherwise in the market – and there are several reasons for this concept: Unlike other hybrid concepts which offer their benefits primarily in town, the system developed by Porsche also offers the opportunity to “sail” along in the Cayenne S Hybrid up to a speed of 156 km/h or 97 mph without using the combustion engine. A further advantage is that parallel full hybrid offers the acceleration and elasticity so typical of a Porsche without the “rubber band” effect of split hybrid systems. All this makes the parallel full hybrid a perfect match for Porsche’s philosophy to offer outstanding performance and supreme efficiency all in one.
A further advantage is the compact size of the system, the complete hybrid module measuring only 147.5 millimetres or 5.8″ in length. Integrated between the combustion engine and the transmission, the hybrid module is made up primarily of a ring-shaped synchronous motor and a separator clutch on the side facing the combustion engine, providing the same flow of power and characteristics as a conventional drive system.
A pioneering achievement from Porsche: intelligent control by the Hybrid Manager
A parallel full hybrid makes substantial demands of the components involved and the con trol functions. Interaction of the main components – the combustion engine, the electric motor, the separator clutch, and the battery – is extremely complex and is coordinated by the Hybrid Manager using all the know-how of the Porsche hybrid system. The Hybrid Manager receives all driving and energy information and controls both the electric motor and the combustion engine for optimum fuel economy under all conditions. It also makes sure that the battery does not run too flat nor that it is charged and de-charged too often.
Another key component of parallel full hybrid drive is the separator clutch between the combustion engine and the electric motor using particularly strong and resistant friction pads. The separator clutch works so smoothly and sensitively that the driver will not even notice the combustion engine engaging and disengaging, although the full power of both drive units is always available without the slightest delay for fast and powerful acceleration. This means that with the combustion engine switched off all the driver has to do to start the engine almost immediately is press down the gas pedal, the engine revving up spontaneously and the clutch engaging without the driver even noticing the entire process.
The Porsche Cayenne S Hybrid does all this in just 300 milliseconds, performing several processes all at the same time: As soon as the combustion engine cuts in the converter lockup clutch on the torque converter in the automatic transmission opens up and the torque coming from the electric motor is briefly increased to start the six-cylinder. At the same time the clutch between the electric motor and the combustion engine closes in a defined pressure curve within 70 milliseconds.
Apart from the intricate interaction of the combustion engine and the electric motor, all this is ensured by the innovative spindle actuator in the clutch control unit masterminding the hydraulic pressure operating the clutch with a level of precision never seen before.
Every time the engine cuts in the Hybrid Manager evaluates current driving conditions and the driver’s wish for acceleration, choosing the appropriate starting procedure – either a “comfort start” of the combustion engine or, if the driver wishes to enjoy more power, a particularly spontaneous “power start”.
Additional reduction of fuel consumption: sailing up to 156 km/h (97 mph)
Using the separator clutch, Porsche full hybrid drive is also able to offer a further reduction of fuel consumption at higher speeds by driving in the “sailing” mode: Whenever the driver does not need any drive power, all he has to do is take back the gas pedal to completely dis connect the combustion engine from the drivetrain at speeds of up to 156 km/h (97 mph). The driver is therefore able to eliminate engine drag forces with their strong braking effect while sailing, thus reducing both drive resistance and fuel consumption.
In the sailing mode the electric motor operates as a generator, delivering electric power.
Should the driver accelerate in the sailing mode, for example when overtaking, the combustion engine starts again quickly and smoothly within fractions of a second, revving up to the appropriate engine speed matching the actual speed of the vehicle. As a result, the driver is able to accelerate spontaneously also at this speed, just like in a Porsche Cayenne with a conventional power unit.
The sailing mode is available from low road speeds and start automatically once the driver takes his foot off the gas pedal, opening up the separator clutch and automatically switching off the combustion engine. “Sailing” is therefore equal to gliding or simply “rolling along” without using the power of the combustion engine or electric motor.
The Porsche Cayenne S Hybrid delivers its maximum output in the boost mode, adding the drive power of the combustion engine and the electric motor to one another as a big advantage of the parallel full hybrid concept: While the combustion engine develops its maximum torque of 440 Nm (324 lb-ft) in the range between 3,000 and 5,250 rpm, the electric motor is able to use its full torque of up to 300 Nm/221 lb-ft all the way from a standstill.
Maximum output of the two drive units of 380 hp comes at 5,500 rpm, while combined torque of 580 Nm/427 lb-ft cuts in at just 1,000 rpm for truly muscular acceleration at all times.
With the maximum torque of the two drive units being developed in different speed ranges, it is not possible to simply add up the maximum torque figures. Since the torque delivered by the electric motor drops again at higher speeds, the combustion engine continuing to benefit from the electric motor ensures an ongoing, consistent and efficient torque curve also at high engine revs, the two drive units supplementing each other perfectly and allowing the driver to use all the superior power of the system throughout the entire range of engine speed.
The Porsche Cayenne S Hybrid thus benefits from the intelligent interaction of both power units through its particularly sporting acceleration from a standstill and superior driving dynamics also at high speeds, for example when accelerating.
With the Porsche Cayenne Sports Button in the normal mode, the electric boost effect is available immediately through the kick-down function. With the Sports Button activated, the boost range is shifted forward and the two drive units interact with one another as soon as the driver presses down the gas pedal with maximum force by 80 per cent.
E-Power Button extends driving range under electric power
Activating the E-Power Button in the centre console, the driver is able to extend the availability of the all-electric driving mode. Activation of the button is displayed by an LED on the button itself and by the word “E-Power” coming on in blue in the instrument cluster.
Availability of E-Power depends on parameters such as the battery charge status and battery temperature. The E-Power mode modifies the gas pedal control map, allowing the system to follow the driver’s wish for acceleration much more smoothly and preventing the combustion engine from cutting in automatically at a too early a point whenever the driver wishes to use more power.
Saving fuel by generating electric power
A further fundamental benefit offered by the Hybrid Manager is its ability to shift the load point when driving with the combustion engine: Every power unit operates most economically within a certain load range. Whenever the six-cylinder runs below this point under part load, the Hybrid Manager automatically gives more gas and uses this extra power to generate electric energy. The generator output and the opening of the throttle butterflies are therefore controlled in the most appropriate way for running the combustion engine with greater efficiency, making optimum use of the fuel available and “parking” some of the electrical energy generated in the battery.
All this goes unnoticed to the driver, with both engine and road speed remaining unchanged. In other words, the Porsche Cayenne drives as if it were moving up from a flat stretch of road to a gradient with cruise control switched on, the car thus travelling at the same, consistent speed.
Last but certainly not least, the Hybrid Manager makes sure that when pressing down the brake pedal as much energy as possible goes from the electric motor operating as a generator to the battery. To ensure this effect, the control system sets the power of the generator to the travel of the brake pedal, ensuring that the vehicle is braked in part – in some cases completely – by electric power alone, the conventional brake system only cutting in at higher speeds and under greater brake power.
High-power traction battery
The Porsche Cayenne S Hybrid uses a nickel metal-hydride battery as its traction battery – that is battery technology already proven in the automobile.
The nickel metal-hydride battery does not require any maintenance and is gas-tight, fitting conveniently thanks to its compact dimensions beneath the completely flat floor of the luggage compartment to retain the substantial luggage capacity offered by the Cayenne.
The battery generates maximum output of 38 kW and saves up to 1.7 kilowatt hours of energy. The effective battery capacity is presented clearly in per cent both in the instrument cluster and on the monitor of the optional PCM Porsche Communication Management control unit.
The battery is charged while driving through the recuperative brake energy process and by shifting the load point of the combustion engine for optimum fuel efficiency. Again under practical conditions, the battery is able to re-gain the energy of up to one litre of fuel every 100 kilometres on the road. The energy saved, in turn, may be used to drive exclusively on electric power without using the combustion engine or to support the combustion engine while driving.
Weighing approximately 80 kg or 176 lb together with its frame, the battery is made up of 240 cells generating the power required of 288 volts. With its operating range starting at -30°, the battery offers excellent starting performance even in – very – cold conditions. At the same time the temperature range goes all the way to 40° C or 104° F, meaning that the battery covers virtually the entire range of temperatures the driver will experience in the car.
When charging and de-charging, the battery generates heat which must be dissipated in order to protect the battery cells. Climatised air from the interior is therefore used to cool the battery, being drawn in from the passenger compartment through ducts beneath the rear seat bench.
In addition to this new technology, the Porsche Cayenne S Hybrid comes with a conventional 12-volt battery beneath the driver’s seat supplying energy to the vehicle’s on-board network. This 12-volt battery may be re-charged by a conventional battery charger, while at the same time the Porsche Dealer and Service Station is able to charge the traction battery via a high-voltage connection and an appropriate charge unit.
In the parking mode the Battery Manager regularly checks the charge status of the battery and the individual voltage levels within each cell. To optimise the charge status of the complete battery and keep cell voltage within its tolerance limits, battery charge may be automa tically balanced between the cells or the cells may be de-charged in an appropriate process.
When parking the entire high-voltage circuit is opened up by a high-performance switch, preventing electric power from leaking while the car is at a standstill and securing the traction battery against any unwanted self-discharge.
When the driver starts the car with his key, finally, the battery activated via the 12-volt onboard network operates the protector switch to start the combustion engine via the battery and to close the high-voltage circuit once again.
Powerful and fuel-efficient: the engines
The new Cayenne comes with an upgraded generation of the engines already featured in the former models: the Porsche Cayenne boasts a 3.6-litre V6 naturally-aspirated power unit with output increased to 300 hp, the Cayenne Diesel comes with a high-torque 3.0-litre V6 turbodiesel, and the Cayenne S as well as the Cayenne Turbo both feature a supreme 4.8-litre V8.
All of the engines have been upgraded and updated in their essential features, resulting in part in a slight increase in engine output and a significant reduction of fuel consumption on all models.
For the first time the new Porsche Cayenne comes with map-controlled thermal management masterminding the processes taking place in the vehicle. Forming part of the thermal management system, the radiator features two cooling circuits activated as a function of coolant temperature by a thermostat for automatic, on-demand interruption of coolant supply as long as the engine is cold. This enables the engine to warm up more quickly, at the same time reducing friction, fuel consumption and emissions in the warm-up phase.
Depending on the increase in engine temperature, coolant is allowed to flow through the engine (in the so-called small circuit) while warming up, activating the main radiator as a function of the engine’s operating point (main coolant circuit). This thermal management alone reduces fuel consumption by up to 1.5 per cent by making the warm-up period shorter after the engine has been started cold.
All new versions of the Porsche Cayenne with Tiptronic S also come with separate thermal management on the transmission. Here again, the objective is to reach the optimum operating temperature as quickly as possible in order to minimise friction losses – which is why the heat exchanger on the coolant circuit of the new eight-speed Tiptronic S transmission is directly connected to the cooling circuit on the engine. This allows quicker use of the heat in the engine coolant warmed up more quickly whenever necessary, warming up the transmission to its best operating temperature with greater efficiency.
Yet a further function serving to reduce fuel consumption is on-board network recuperation. This system shifts the generation of energy through the alternator for charging the starter battery in all new versions of the Cayenne to the actual application of the brakes while the vehicle is slowing down, thus retaining part of the kinetic energy saved in the starter battery. When driving at a steady speed and when accelerating, on the other hand, the alternator delivers as little energy as possible and the on-board network is supplied primarily from the starter battery charged during application of the brakes. This relieves the combustion engine from the usual need to charge the alternator, which again means a direct reduction of fuel consumption. In the New European Driving Cycle, for example, recuperation of energy supplied to the on-board network reduces fuel consumption by 0.15 litres/100 kilometres.
New: Auto Start Stop and variable overrun control
All new versions of the Porsche Cayenne with eight-speed Tiptronic S transmission optional on the base model and standard on all others, come with an Auto Start Stop function. Auto Start Stop switches off the combustion engine under defined conditions as long as the vehicle is at a standstill, reducing fuel consumption and emissions in the process and thus preventing the engine from idling unnecessarily, for example when stopping at the traffic lights.
As soon as the vehicle comes to a halt due to application of the brakes, with the driver holding the brake pedal in position, the Auto Start Stop function will switch off the engine after about a second, informing the driver accordingly through the green Auto Start Stop symbol in the instrument cluster.
In the process the driver may leave the selector lever in position D or M, and the engine will remain inactive also when shifting to P and N. Once the driver lets go of the brake pedal, the engine will start again and the driver can set off without a delay. For reasons of safety, however, this is not possible if the driver’s door or the engine compartment lid are open or if the driver is not wearing his seat belt.
Under certain conditions the engine is intentionally not switched off when coming to a halt, for example when the driver has activated the Sports Mode, when towing a trailer or when the vehicle is in a parking or manoeuvring process. In such cases the driver is informed by a yellow Auto Start Stop symbol in the instrument cluster that the system has not switched off the engine.
A further new feature is variable overrun control, a further development of the conventional overrun switch-off function. In principle, overrun control switches off the supply of fuel in overrun whenever the combustion engine is in overrun, with the driver easing back the gas pedal, for example when approaching the traffic lights or driving downhill.
Compared with conventional overrun control starting to inject fuel again as of a certain engine speed, fuel injection starts much later with variable overrun control as a function of driving conditions, helping to save even more fuel in the process.
The six-cylinders: three engines, three concepts
Porsche is able to offer no less than three six-cylinder V-engines with direct fuel injection in the new generation of the Cayenne: The Cayenne boasts Porsche’s upgraded 3.6-litre power unit, the new Cayenne S Hybrid comes as the first Porsche with a supercharged three-litre. The Cayenne Diesel, finally, features a three-litre turbocharged engine based on the power unit already to be admired in the former model.
Apart from the significant reduction of fuel consumption, the objective in upgrading the engine in the Porsche Cayenne was to achieve more power and torque. Hence, the increase in engine power by 10 hp to 300 hp (220 kW) and the increase in torque by 15 Nm/11 lb-ft to a new peak of 400 Nm/295 lb-ft at 3,000 rpm are the result of a whole range of improvements. Just three examples are the optimised hot-film air mass metre, the reduction of friction losses within the engine, and the new set-up of electronic engine management.
New thermal management, variable overrun control and Auto Start Stop in conjunction with the new eight-speed Tiptronic S all help to ensure a higher level of efficiency. This gives the new Cayenne with optional Tiptronic S overall fuel consumption in the New European Driving Cycle of just 9.9 ltr/100 km (equal to 28.5 mpg imp), about 20 per cent better than on the former model. Combined with the standard manual gearbox without Auto Start Stop, fuel consumption is 11.2 ltr/100 km (equal to 25.2 mpg imp), still a reduction by about 10 per cent from the former model.
Introducing these new technologies, Porsche’s engineers are focusing not only on fuel economy and performance, but also on specific features serving to optimise running smoothness and motoring comfort on the road. In the upgraded 3.6-litre V6, these improvements include a forged steel crankshaft serving not only to save weight, but also to improve engine smoothness. And with the help of the electronic dipstick, the driver is now able to check the engine oil level while idling without having to open up the engine lid.
First-time achievement from Porsche: supercharged six-cylinder
The power unit featured in the new Porsche Cayenne S Hybrid marks an important premiere with Porsche not just because of the additional electric motor – rather, this is the first time that Porsche is using a V6 with direct gasoline injection and supercharging as the primary source of power. Displacing exactly 2,995 cc, this outstanding power unit delivers maximum output of 333 hp (245 kW) all the way from 5,500 – 6,500 rpm, with peak torque of 440 Nm/324 lb-ft maintained consistently from 3,000 – 5,250 rpm.
Apart from providing the performance and driving qualities so typical of Porsche together with the supreme power of a V8, the big advantages of this engine are low fuel consump tion, reduced CO2 emissions, and the fulfilment of all emission standards the world over. As a result, the Cayenne S Hybrid offers the efficient performance rightly expected of a Porsche in a new and truly convincing manner.
The engine is a four-valve power unit with two camshafts on each row of cylinders and a cylinder bank angle of 90°. Like the V8 power unit in the Porsche Cayenne S and Cayenne Turbo, the new three-litre V6 features an aluminium engine block, an aluminium cylinder head, as well as modern engine technology such as thermal management and a fully controlled oil pump. And like on the other V6 power units, the oil supply system uses wet sump lubrication.
Unlike Porsche engines so far, the new power unit is boosted not by exhaust gas turbo chargers, but rather by a supercharger interacting with an intercooler. The reason, quite simply, is that this concept offers clear benefits for the specific purposes and characteristics of parallel full hybrid drive in an SUV: With the supercharger featuring a permanent mechanical link to the crankdrive, charge pressure is immediately available and the flow of air mass increases consistently as a function of engine speed. The position of the supercharger within the V-section of the two rows of cylinders keeps the travel distance for intake and compressed air flowing to the cylinders short and dynamic, giving the supercharged engine a spontaneous response and muscular torque at low engine speeds. And last but not least, the engine runs perfectly in unison with the electric motor.
The supercharger is a Roots blower complete with a bypass. Two parallel shafts connected by gears in the supercharger housing are driven by separate belt drive, while rotors on each of the two shafts seal off the system at all sides, that is against the blades of the opposite rotor and the supercharger housing.
Moving in opposite directions, the two shafts convey the air without compression between the rotors from the air intake in the supercharger to the air outlet. The rotors each come with four vanes and are set off the longitudinal axis by a total of 160° to ensure a smooth and continuous supply of air. The compression effect is provided by ramming the air into the air mass built up upstream of the intake valves. To improve the charge effect, finally, the supercharger comes with an intercooler featuring a low-temperature cooling circuit on each row of cylinders.
Since charge air is not required under all driving conditions and the ongoing build-up of charge pressure would create an air jam and, accordingly, a loss of power, the supercharger comes with integrated boost pressure control. Instead of an elaborate control system using a magnetic clutch to connect and disconnect the compressor, the system chosen in the Cayenne features a fully-controlled bypass flap.
Fuel-efficient and clean: V6 diesel
Focusing on the three-litre turbodiesel in the Cayenne Diesel, Porsche’s engineers sought above all to further reduce fuel consumption and exhaust emissions in the process of upgrading the engine. The result is that with power remaining unchanged at 240 hp (176 kW) and torque reaching an impressive 550 Nm/405 lb-ft, fuel consumption is down from an already low 9.3 ltr (equal to 30.4 mpg imp) to truly outstanding 7.4 ltr/100 km, equal to 38.2 mpg imp. At the same time it almost goes without saying that the new Porsche Cayenne Diesel complies in full with the EU5 emission limit.
Fuel is injected into the combustion chambers by piezo-valves building up pressure of up to 1,800 bar. The charge effect is provide by turbochargers with variable turbine geometry (VTG turbochargers), with fully controlled exhaust gas recirculation, an oxidation catalyst, as well as a particulates filter ensuring highly effective emission management.
An essential feature in enhancing the engine’s efficiency was to integrate a fully controlled oil pump. Now the oil pump is controlled on-demand by engine management, with oil pressure being adjusted hydraulically by moving a gear wheel along the pump shaft and thus varying the level of geometric volume. As a result, the pump only operates as required to meet current engine requirements at the respective load level.
Being appropriately optimised, exhaust gas recirculation (EGR) serves to minimise emissions and help the engine fulfil the EU5 emission standard. The exhaust gas recirculation module now comes with a higher level of cooling efficiency and, as a result, greater throughput. A further result is the reduction of peak temperatures in the combustion process, with less nitric oxides being formed in the combustion chamber.
Superior power with even greater efficiency: the V8 power units
The fully upgraded family of V8 power units is made up of the even more powerful 4.8-litre naturally-aspirated engine now delivering 400 hp and 500 Nm/369 lb-ft maximum torque in the new Porsche Cayenne S and a turbocharged 500 hp together with 700 Nm/516 lb-ft in the new Cayenne Turbo.
With the two power units being designed and upgraded together, the natural-aspiration and the turbocharged engine share a particularly large number of common parts. And once again it almost goes without saying that the new V8 engines featured in the Cayenne S and the Cayenne Turbo come with all new technologies to reduce fuel consumption, such as thermal management, on-board network recuperation, variable overrun control, and the Auto Start Stop function.
The proven light-alloy block of the V8 power units is further enhanced by the even more comprehensive use of aluminium and magnesium, saving approximately 7 kg or 15 lb in weight on the valve timing cover, the valve cover itself, the camshaft adjuster, various bolts, and the crankdrive. As an example, the new generation of V8 power units comes with a new lightweight camshaft adjuster for adjusting valve timing through VarioCam Plus made completely of aluminium. This alone reduces engine weight by approximately 1.7 kg or 3.8 lb, minimising the rotating masses in the process, improving the speed of adjustment, and giving the engine an even more agile response.
Both power units now feature pressure-controlled measurement of air mass instead of a hot-film air mass metre, with the advantage of lower intake air resistance and an even better flow of air.
On the normal-aspiration power unit in the Porsche Cayenne S a newly developed, lighter crankshaft and lighter connecting rods reduce the movement of masses and weight within the engine. In all, the crankdrive on the eight-cylinder is 2.3 kg or 5.1 lb lighter than before.
A further feature on the eight-cylinder is the oil flow housing made of magnesium, again reducing engine weight by approximately 2 kg or 4.4 lb. The intake camshafts, to mention yet another example, have been optimised for a very smooth flow of power and torque. Together with the new intake system boasting a larger throttle butterfly and optimised electronic engine management, the 4.8-litre naturally-aspirated V8 now delivers maximum output of 400 hp at 6,500 rpm.
In combination with other technologies serving to reduce fuel consumption, these modifications also help to ensure optimum fuel economy: The new Cayenne S requires just 10.5 ltr/100 km (equal to 26.9 mpg imp) in the New European Driving Cycle, approximately 23 per cent less than its predecessor. CO2 emissions, to mention another example, are down 26 per cent to 245 g/km.
The V8 biturbo engine featured in the Porsche Cayenne Turbo comes with a new, weight-optimised crankshaft and a new oil flow housing made of aluminium. The crankshaft features a larger counterweight radius than the former crankdrive, with the overall weight of the crankdrive down by 0.6 kg or 1.3 lb.
Reduction in weight and the latest engine technology makes the turbocharged 4.8-litre power unit in the Cayenne Turbo even more efficient, with average fuel consumption in the New European Driving Cycle of just 11.5 ltr/100 km (equal to 24.6 mpg imp), 23 per cent less than on the former model.
At 270 g/km, CO2 emissions are down 25 per cent versus the former Porsche Cayenne Turbo. Performance, on the other hand, is even better than before, the new Cayenne Turbo reaching a top speed of 278 km/h or 172 mph and accelerating from a standstill to 100 km/h in just 4.7 seconds.
Ultra-modern exhaust systems – as an option also in sports trim
To fulfil all emission standards the world over, all models in the Porsche Cayenne range come with an exhaust system specially tailored to each engine. All exhaust units are made of long-life stainless steel.
To keep emissions low particularly when starting the engine cold, the catalytic converter must be heated up quickly to its optimum operating temperature. This is done by keeping the exhaust manifolds on all models very short, using the high temperature of the exhaust gas to heat up the catalytic converters. As a result, the highly effective pre- and main catalysts are able to warm up more quickly, guaranteeing highly effective management of exhaust emissions.
The Cayenne with its optional Tiptronic S and the Cayenne S are both available as an option with a sports exhaust system generating an even throatier and more voluminous sound.
The sports exhaust system is adjusted and set up by the Sports Button featured as standard on the centre console.
First Tiptronic S with Eight Gears
Porsche has developed the first Tiptronic S with eight gears for the new Cayenne model series. This highly advanced transmission comes as standard on all models in the range, with the exception of the 3.6-litre Porsche Cayenne fitted as standard with a six-speed manual gearbox.
Introducing this new eight-speed Tiptronic S, Porsche is offering a transmission in the Cayenne family which stands out in particular through its superior efficiency and fast gearshift for supreme shift and driving comfort. The overall range of gear spread up by 20 per cent, for example, is used completely to make the two additional gears genuine overdrive or economy gears consistently keeping the engine in the optimum speed and load range at all times: Engine speed is reduced by 20 per cent, respectively, in the seventh and eighth gear, serving to substantially reduce fuel consumption particularly on long stretches of the Autobahn. In practice this means an even bigger improvement in fuel economy under everyday driving conditions than in the standardised measuring cycle.
To optimise the engine’s starting behaviour, the Porsche Cayenne with its new eight-speed Tiptronic S always sets off in first gear. Top speed, on the other hand, comes in sixth gear.
Gearshift up to 0.15 seconds faster on the new transmission ensures maximum agility and driving pleasure at all times. Indeed, the entire process of shifting gears is so smooth that the driver hardly notices any change in gears.
The fast gearshift with hardly any interruption of traction and pulling power allows a very agile style of motoring also in the automatic mode. The technology responsible for this even faster gearshift is the new configuration of the hydraulic gearshift units with direct control of the valves and optimised engagement use of the shift functions.
Tiptronic S: programmed for individual driving profiles
Benefiting from intelligent gearshift programs, the driver is able to control the shift behaviour of the Tiptronic S transmission through the gas and brake pedals. When moving the gas pedal abruptly, the shift points are moved immediately into the dynamic control map, without requiring the usual kick-down effect.
This prevents the transmission from shifting up under overrun whenever the driver takes back the gas pedal abruptly, for example in a bend. At the same time the appropriate gear is held in position to avoid shifting up in a bend, making the vehicle even more stable and safer on the road.
When applying the brakes hard, on the other hand, Tiptronic S shifts down quickly to the next lower gear to use the full brake effect of the engine. Gradient recognition, finally, ensures even better acceleration uphill and extra brake force from the engine when travelling downhill.
As in the past, the driver has the choice of the two Normal and Sports modes. Within these basic programs, the gearshift control maps are adjusted even more sensitively to the driver’s individual style of motoring.
To ensure maximum performance immediately when activating the Sports Button, the control maps on the Tiptronic S transmission shift faster to the sports map than in the Normal mode, suppressing gears 7 and 8 as a function of the driver’s style of motoring and the speed of the car, and shifting back when braking even under slight brake pressure in order to provide better acceleration afterwards.
In the Normal mode Tiptronic S offers a particularly economical style of motoring, reducing fuel consumption by shifting up early and shifting down late.
In its gearshift characteristics, the transmission in the Cayenne S Hybrid is adapted to the wider range of driving conditions this vehicle has to offer. This is indeed essential to increase the recuperation effect on the brakes by adjusting shift speeds (when shifting down) or to re-start the combustion engine smoothly and comfortably when leaving the all-electric mode and shifting gears only rarely.
This special set-up of the eight-speed Tiptronic S transmission also offers the optimum gearshift strategy when boosting, with additional drive power coming from the electric motor.
Offroad set-up for rough terrain The Tiptronic S transmission also comes with a special offroad mode for rough terrain (with the exception of the Cayenne S Hybrid).
As soon as the driver activates Offroad Mode 1 by pressing the central offroad toggle switch on the centre console, Tiptronic S switches to a gearshift program specially tailored to offroad requirements and focusing in particular on extra traction and the precise dosage of engine power.
Shifting up later and shifting down earlier, this special mode reduces the number of gearshifts by making maximum use of the speed range available in each gear. To ensure optimum control of the vehicle, the transmission does not shift up or down automatically in the manual mode, even when the driver kicks down the gas pedal. A further feature is that the converter lock-up clutch closes at a later point than in the Normal and Sports Mode, allowing better dosage of power particularly at low speeds and in rough terrain.
The driver will generally operate the new eight-speed Tiptronic S transmission via the selector level in the centre console or the two push buttons on the steering wheel. Pressing one of the two buttons forward, he shifts up Tiptronic S, pulling one of the buttons towards himself from behind the steering wheel, the driver shifts down in Tiptronic S.
A three-spoke sports steering wheel with shift paddles is also available.
The driving mode and the gear selected by the driver are both presented in the engine speed digital display, an upshift lock ensuring a sporting and direct feeling at the wheel at all times by preventing the transmission from shifting up automatically with the gas pedal down 100 per cent when reaching the speed limiter. In that case the transmission will shift up only when the driver operates the selector lever, pushes the buttons on the steering wheel, or kicks down the gas pedal.
With its new Auto Start Stop function, every new Porsche Cayenne enables the driver to save extra fuel in town. Combining this function with an automatic transmission was a particular challenge for Porsche’s engineers, ensuring that the Cayenne is able to set off again immediately after the engine is re-started. To do this after having come to a halt, the engine and transmission require sufficient oil pressure to ensure the slip-free transmission of power.
On a conventional automatic transmission pressure is built up by a mechanically driven transmission fluid pump able to provide the oil pressure and volume flow for setting off only when the engine has reached a higher speed. With the additional electric oil pump on the new Tiptronic S transmission, on the other hand, a sufficient supply of oil for the shift units is maintained also while the engine has come to a halt. This makes it possible to minimise the response time of the transmission, the vehicle setting off after an Auto Start Stop virtually without the slightest delay, and the driver and passengers not noticing any difference from a vehicle with the engine already running.
Porsche’s new eight-speed Tiptronic S is based on the former six-speed automatic transmission, extended by an additional shift element providing the two extra gears. The front and rear planetary gearsets have been re-configured to provide a broad spread of transmission ratios.
A further advantage is that the new transmission does not require any more space than the former unit, with the eight-speed transmission measuring exactly the same in length as the former six-speed gearbox. The better power-to-weight ratio of the transmission, a higher degree of efficiency and the optimisation of individual components likewise serve to enhance the overall level of efficiency, high-performance vibration dampers in the converter lock-up clutch, for example, allowing the engine to run with the converter locked up at far lower speeds in the interest of greater fuel economy.
Fuel-saving thermal management also with Tiptronic S
To reach the optimum operating temperature as quickly as possible after starting cold and thus minimise friction within the transmission, the new Tiptronic S for the first time comes with thermal management connecting the transmission’s cooling circuit with the engine’s cooling system via a heat exchanger. Depending on individual requirements, this ensures exactly the right exchange of heat between the engine and transmission and helps to further reduce fuel consumption on the new Cayenne. With the engine being started cold, for example, the cooling circuit on the transmission is warmed up by the engine coolant heating up more quickly, thus reducing frictional resistance in the transmission as quickly as possible. Then, with temperatures increasing, the heat exchanger is used exclusively for cooling.
Should the cooling effect of the heat exchanger not be sufficient, the system will resort to the air heat exchanger with its higher capacity fitted in the front of the vehicle.
Tiptronic S in the new Porsche Cayenne S Hybrid differs in various details from the eight-speed automatic transmission featured in the other models. As an example, the two oil pumps generate a higher volume flow required specifically under high loads, for example when boosting or in the recuperation mode, in order to convey high transmission forces. In that case the electrical oil pump is added on individually as required.
The manual six-speed gearbox in the “base” version of the Cayenne is perfectly matched to the high output and specific characteristics of the six-cylinder power unit. The final drive ratio ensures excellent performance, superior driving qualities on long distances, and a high level of comfort.
The transmission communicates with the driver through an upshift display in the instrument cluster, advising the driver to shift up one gear in the interest of fuel economy as a function of the gear in mesh, engine speed, and the position of the gas pedal. The two-mass flywheel integrated between the engine and transmission, finally, ensures a high standard of motoring comfort by minimising vibrations while driving.
Porsche Traction Management with a new concept
Porsche has developed a new concept of all-wheel drive for the new Cayenne, focusing in the process on two factors in particular: lower weight and even greater agility on the road.
Introduction of the new Porsche Traction Management (PTM) together with eight-speed Tiptronic S avoids the need for a reduced-ratio gearbox without making any concessions in terms of offroad requirements relevant to the customer under normal conditions.
A further advantage of the new PTM is the introduction of numerous measures for the reduction of weight on the rest of the drivetrain. In all, the use of lightweight propeller shafts, lighter final drive units front and rear, and the absence of a reduced-ratio gearbox saves some 33 kilos or 73 lb in weight.
The focus in developing PTM was on optimising driving dynamics on the road while retaining the outstanding offroad qualities of the Porsche Cayenne. The result is two different PTM systems geared to the specific characteristics of the new models: In the Cayenne Diesel and the Cayenne S Hybrid, PTM comes with permanent all-wheel drive complete with a self-locking centre differential. In the Cayenne, Cayenne S and Cayenne Turbo, on the other hand, PTM features active all-wheel drive with an electronically controlled, map-guided multiple-plate clutch.
This active all-wheel-drive system is featured on the particularly sporting and dynamic versions of the Porsche Cayenne because, with its wide range of power and torque distribution, hangon all-wheel drive offers benefits in terms of driving dynamics, agility and traction control, thus highlighting the performance of the specific models concerned.
Permanent all-wheel drive with a self-locking centre differential, on the other hand, is reserved to the Cayenne Diesel and the Cayenne S Hybrid. Variable engine and torque distribution on the rear axle featured as standard nevertheless ensures the performance and driving dynamics typical of a Porsche also with PTM featuring permanent all-wheel drive.
Under all conditions Porsche Traction Management distributes drive power as required from the rear to the front axle, thus combining superior traction and driving stability with unusually dynamic handling. The extremely compact power divider on the all-wheel drive unit featured in the new Porsche Cayenne is housed in a separate casing directly next to the transmission.
PTM also comes with the ABD Automatic Brake Differential for improved traction, ASR Anti- Slip Control for improved vehicle stability, and on-demand PHC Porsche Hill Control for driving down steep gradients in a smooth and controlled process.
All-wheel drive adjustable individually on each model by the offroad lever
Depending on the specific version of the Cayenne, the driver is able to adjust the car’s offroad abilities in various stages.
All systems are therefore optimised for offroad requirements with the objective to improve traction on rough terrain. A separate switch on the Porsche Cayenne S Hybrid, for example, serves to activate Porsche Hill Control as an assistance function cutting in as of a gradient 12 per cent.
The Cayenne, Cayenne S, and Cayenne Turbo offer further functions operated via a central offroad switch in the centre console: In Offroad Mode 1 all relevant systems such as ABS operate in a traction-oriented offroad program, in addition to Porsche Hill Control. On models with air suspension and PSM, in turn, the suspension automatically switches to the offroad level.
The toggle switch for the air suspension also allows the driver to choose the special offroad level for an even greater embankment and ramp angle as well as greater ride height for driving through water.
Given their active all-wheel-drive system, the Cayenne, Cayenne S, and Cayenne Turbo come with yet another optional setting: As soon as the driver selects Offroad Mode 2, the longitudinal clutch is closed 100 per cent of even better traction on difficult terrain. At the same time the electronically controlled rear axle differential on the optional Porsche Torque Vectoring Plus (PTV Plus) is integrated in the all-wheel-drive management, automatically ensuring the right dosage of power on particularly bad and rough terrain. Should one of the rear wheels start to slip on slippery or loose ground, for example, the differential lock will smoothly feed drive power to the opposite rear wheel in order to re-gain traction. And should conditions require, all the driver has to do is press the offroad toggle switch for Offroad Mode 3, fully closing the rear axle differential in the process.
Active or permanent all-wheel drive, depending on the character of each model
Porsche Traction Management with active all-wheel drive acts directly on the rear axle. The multiple-plate clutch controlled electronically by an electric motor masterminds the flow of drive power to the front axle in a fully variable process without any fixed distribution.
With slip building up on the rear axle, for example when accelerating, the multiple-plate clutch cuts in harder to feed more drive power to the front axle. Permanently monitoring driving conditions, the system is furthermore able to respond to different situations and requests from the driver, allowing appropriate, dynamic management of active all-wheel drive even able to respond individually and preventively before any unwanted slip is able to build up on one of the axles.
An example: If the driver is steering into a bend, side forces on the wheels steered are increased by reducing the level of drive power on the front axle, thus allowing a high standard of agility and lateral acceleration. Then, when the driver accelerates out of the bend, drive power is spread out evenly between the two axles for maximum traction.
Featuring this technology, active all-wheel drive in the new Porsche Cayenne is identical to the allwheel- drive system to be seen in the Panamera and Porsche’s sports cars. At the same time maximum attention has been given to the complex interaction of onroad and offroad requirements on the new Cayenne, which therefore further increase their leading position over their competitors also in this respect.
Permanent all-wheel drive on the Cayenne Diesel and Cayenne S Hybrid is laid out to convey 60 per cent of the drive power to the front axle and 40 per cent to the rear axle under normal conditions. Whenever a wheel on one of the axles starts to spin – for example when running on ice – the difference in speed between the two axles automatically activates the self-locking centre differential, more drive power flowing to the axle with better traction.
Porsche Torque Vectoring Plus for even greater agility
As an option active all-wheel drive on the Cayenne, Cayenne S, and Cayenne Turbo may for the first time be upgraded by new PTV Porsche Torque Vectoring Plus.
PTV Plus serves to enhance both driving dynamics and stability, using variable distribution of drive power on the rear wheels and an electronically controlled cross differential on the rear axle.
Depending on the steering angle and steering speed, the position of the gas pedal, the yaw rate and road speed, PTV Plus improves the vehicle’s steering behaviour and steering precision by the brakes intervening as required on one of the rear wheels. To be more precise, the inner rear wheel in a bend is slowed down slightly when the driver turns the steering while driving dynamically on the road. This feeds more power to the outer rear wheel and generates an additional turning motion in the desired direction. The result is even more direct and dynamic steering in a bend.
At low and medium speeds PTV Plus means a significantly higher standard of agility and steering precision. Particularly when accelerating out of a fast bend, and with the wheels spinning, the electronically controlled rear axle differential serves additionally to enhance the level of driving stability.
Interacting with Porsche Traction Management and Porsche Stability Management, PTV Plus also offers enhanced driving stability on various road surfaces, in wet weather and on snow. Under offroad driving conditions, in turn, PTV Plus prevents the rear wheels from spinning.
Yet a further advantage is that any intervention of the brakes is specifically tailored to offroad requirements, the offroad toggle switch in the centre console enabling the driver to apply the rear axle differential lock 100 per cent.
Sporting, Comfortable, Safe
Once again Porsche’s engineers have succeeded in making the already excellent driving characteristics of the Cayenne significantly better. And once again, the name of the game is lightweight construction, even greater use of aluminium and special plastic materials as well as constructional improvements reducing the weight of the vehicle by some 66 kg or 145 lb. The reduction in weight achieved in this way not only increases the standard of driving dynamics on lower fuel consumption, but also, by reducing the unsprung masses, serves to significantly enhance the standard of driving comfort.
With the exception of the Porsche Cayenne Turbo, all models comes as standard with steel springs which may for the first time be combined as an option with PASM Porsche Active Suspen sion Management, making the steel suspension even better in providing superior long-distance comfort, even better performance, and supreme agility.
Porsche Active Suspension Management is a bumper system for active, infinite adjustment of the dampers front and rear. On the new Cayenne the driver is able to choose three different programs by means of the PASM suspension buttons on the centre console: Comfort, Normal, and Sport. Depending on the mode selected, road and driving conditions, PASM controls damper power individually on each wheel for optimum results and qualities.
The Porsche Cayenne Turbo comes with new air suspension and PASM is featured as standard in a combination also available as an option on the other models. All air-sprung struts on the front and rear axle are optimised for minimum weight and are now mounted directly on the body for a significant improvement of both torsional stiffness and driving behaviour.
A further important point is that the new air suspension forms a self-contained system storing air in the system’s high-pressure reservoir upon any change in ride height. Such interim storage serves, first, to save energy by using a compressor optimised to meet the new requirements and, second, enables the suspension to reach the ride height chosen either manually or automatically more quickly than before.
Last but not least, the new air spring system with PASM, featuring a new set-up of the software, provides an even wider spread of driving characteristics in the three Comfort, Normal and Sport programs.
PDCC Porsche Dynamic Chassis Control as an option
On the Cayenne, Cayenne S, and the Cayenne Turbo, the air suspension and PASM may be further enhanced as an option through the addition of PDDC Porsche Dynamic Chassis Control.
PDCC is an active system serving to stabilise the body of the vehicle in bends. It enhances both driving performance and motoring comfort, ensuring dynamic distribution of roll forces in the interest of supreme agility and an optimum balance of the car.
Hydraulic swivel motors on the active anti-roll bars front and rear build up appropriate forces as a function of the steering angle and lateral acceleration counteracting any side roll of the car in bends. The result is an extremely comfortable and, at the same time, a very sporting driving experience combined with supreme agility at all speeds as well as optimum steering behaviour and good load balance behaviour.
The driver is able to switch PDCC to its offroad mode by means of the toggle switch on the centre console, with the two halves of the active anti-roll bars being largely disconnected from one another in this case for even better traction in rough terrain. This allows greater articulation of the axles, keeping the wheels longer on the ground in order to convey more power and drive force.
Brake system optimised on all versions of the Cayenne
To meet the substantial demands made of the brake system of a Porsche, all new models in the Porsche Cayenne come with an even larger, optimised brake system. In terms of their looks, the brakes differ from one another in accordance with Porsche’s well-known colour code: The Cayenne and Cayenne Diesel come with black brake callipers, the brake callipers on the Cayenne S and the Cayenne S Hybrid are in silver, and the Cayenne Turbo boasts red brake callipers.
As an option all models in the range are available with race-proven PCCB Porsche Ceramic Composite Brakes featuring yellow brake callipers.
The front brakes are six-piston aluminium monobloc fixed-calliper brakes with brake discs measuring 350 millimetres/13.8″ in diameter on the Cayenne and the Cayenne Diesel. On the Cayenne S and the Cayenne S Hybrid the discs measure 360 millimetres/14.2″ in diameter. The Cayenne Turbo, finally, comes with special composite brake discs combining an aluminium cover and a grey cast-iron friction ring measuring 390 millimetres/15.4″.
At the rear all models feature four-piston aluminium monobloc fixed-calliper brakes and brake discs measuring 330 millimetres/13.0″ in diameter. The only exception in this case is the Porsche Cayenne Turbo which, on account of its supreme performance, features larger brake discs also on the rear wheels measuring 358 millimetres/14.1″ in diameter and inner-vented for even better dissipation of heat.
The composite brake discs on the front axle of the Cayenne Turbo help to reduce the weight of the vehicle and unsprung masses, ensuring even better grip on the road, enhanced driving and roll comfort, greater agility, and an even higher standard of handling all round.
All new models in the Porsche Cayenne range come with an electrically operated parking brake positioned very conveniently to the left of the steering wheel. Controlled by a button, the electrical parking brake can be activated manually and deactivated by pressing the foot brake. The parking brake is also released automatically after manual operation once the driver presses down the gas pedal to indicate his intention to start off.
Given all these qualities and features, the electrical parking brake ensures even greater comfort and safety when parking the new Cayenne.
Applying the brakes even better than ever: PCCB Porsche Ceramic Composite Brakes
Like all other Porsche models, the new Cayenne is available as an option with high-performance PCCB Porsche Ceramic Composite Brakes tried and tested in motorsport. Indeed, this is the first time that PCCB brakes are also available on the Cayenne and the Cayenne Diesel.
The decisive advantage of these ceramic brakes is the low weight of the brake discs approximately 50 per cent lighter than grey cast-iron discs of the same type and dimensions. A further benefit is that the brakes respond even faster and more precisely under significantly lower pedal force.
PCCB brakes are available as of a wheel size of 20 inches on the Porsche Cayenne Turbo and 19 inches on the other models. On the Cayenne, the Cayenne Diesel, the Cayenne S and the Cayenne S Hybrid the PCCB brakes come with brake discs measuring 390 millimetres/15.4″ in diameter at the front and 370 millimetres/14.6″ at the rear. The Cayenne Turbo features brake discs measuring 410 millimetres/16.1″ in diameter at the front and 370 millimetres/ 14.6″ in diameter at the rear.
Porsche Stability Management for superior driving safety
Enhanced to an even higher level, PSM Porsche Stability Management featured as standard on every model ensures superior active driving safety in terms of both longitudinal and lateral dynamics, while maintaining the agility so typical of a Porsche all the way to the extreme limit.
The PSM set-up has been upgraded for the new generation of models and has been newly adjusted, say, for the combination with new Porsche Traction Management or optional Porsche Torque Vectoring Plus.
Sensors in the PSM system permanently monitor the direction of travel, road speed, the yaw rate and the lateral acceleration of the car. Taking these readings, PSM calculates the actual direction of motion. Should this differ from the desired path and track, PSM will ac tivate the brakes as required on individual wheels in order to stabilise the vehicle.
Steering even more effective than before
The steering on the new generation of the Porsche Cayenne has been completely upgraded and is now even more sporting and dynamic. Particularly around its centre position, it is also more direct.
Variable transmission ratios and the particular set-up of the hydraulic power assistance ensure outstanding agility in the new Cayenne, with the level of efficiency being improved at the same time: The servo pump driven by the combustion engine now operates on demand with the volume flow required being masterminded as a function of driving conditions.
Servotronic standard on the Cayenne S Hybrid and optional on all other models offers steering assistance geared to road speed. At high speeds the steering is firmer, at low speeds the Servotronic power steering moves more easily and smoothly for comfortable manoeuvring.
Unlike the steering systems on the other models, the Porsche Cayenne S Hybrid comes furthermore with electrohydraulic steering, the main difference being the servo pump driven electrically on demand.
New wheels and tyres
The new Cayenne comes on newly developed wheels in unique design measuring 18 – 21 inches. In developing these wheels, Porsche specialists have attached great attention to the reduction of weight in combination with attractive and truly unique design.
The Cayenne and Cayenne Diesel now come as standard with 18-inch wheels. The Cayenne S and Cayenne S Hybrid likewise feature 18-inch wheels, but in different design. The 19-inch wheels on the Cayenne Turbo, finally, stand out in particular through their filigree five doublespoke design, from the start highlighting the enormous power and performance reserves offered by this outstanding model.
The two 21-inch wheels add a particular touch within the wide range of wheels available – both the elegant Cayenne SportEdition wheel and the forged twin-tone 911 Turbo II wheel in its design already well-known form Porsche’s sports cars and the Panamera.
The new Porsche Cayenne also comes with a new generation of tyres further enhanced specifically in terms of their performance, handling, roll resistance, wear and weight. In the process all three fundamental components have been optimised on all of the tyres – the rubber compound, the tyre thread, and the architecture of the tyre structure.
Both summer and winter tyres as well as all-season tyres are naturally available. And finally, TPC Tyre Pressure Control comes as standard on the Cayenne Turbo and is optional on all other models.
Elegance in a New Dimension
The design language of the new Porsche Cayenne is clear and convincing from the very beginning: even more sporting, even more dynamic, even more Porsche at very first sight.
The objectives set in designing the new generation were diverse and challenging from the start. To offer more space within the interior and enhance the level of variability, wheelbase was extended by 40 millimetres or 1.6″, with overall length increasing by 48 millimetres/1.9″. At the same time the new models are 6 millimetres/0.24″ higher and 11 millimetres/0.43″ wider.
This new design gives the Porsche Cayenne an even more muscular and powerful stance on the road, the new model looking much more compact and dynamic despite its larger dimensions. The particular character of a very sporting and dynamic performer car comes out even more clearly from all angles, and the shape and design themes so typical of Porsche are even clearer than before.
From the front the Cayenne is absolutely unmistakable at very first sight, characterised by the larger centre air scoop at the front further accentuated by two smaller air intakes at the side. The newly designed air scoops underline the sporting elegance of the new model and at the same time confirm the superior power and performance the Porsche Cayenne has to offer.
The same self-confident look is conveyed by the wings of the car contoured much more strongly than before and rising up above the engine compartment lid. The greater emphasis given to the engine lid from the front is also borne out by the Powerdome and the new V-shape of the lid again so typical of Porsche.
The front end tapering out low down on the car serves furthermore to lower the visual centre of gravity. And last but not least, the outer air intakes extending far to the outside give even greater emphasis to the special look of the Cayenne reminiscent of a sports car.
All new models share the new headlight graphics with additional lights at the inside so unmistakably Porsche. The darker panels within the headlight units and the silver-coloured rings on the headlights create even greater presence and, together with the positioning lights on the side air intakes, give the Porsche Cayenne an even more striking look of power and performance.
The exterior mirrors on the new Cayenne come in brand-new design flatter than before. With the mirror base positioned on the doorsill – and no longer in the mirror triangle – the new mirrors offer several benefits all in one: In their new position and design, they take up the lines of the front end and form one unit with the overall design of the car. At the same time wind noise is reduced by improved aerodynamics and visibility in tight bends is enhanced by an additional window in the former mirror triangle.
Seen from the front, the various models clearly differ from one another. The V8 models and the Porsche Cayenne S Hybrid are characterised by black air intakes at the side as opposed to the intake louvers finished in body colour on the Cayenne and Cayenne Diesel. The Cayenne Turbo, in turn, stands out clearly from the other models through the unique design of its centre air intake and the more distinctive Powerdome.
The night design of the new models is also new. Accordingly, all new models in the Porsche Cayenne range now come with LED daytime driving lights integrated as one unit in the sidelights positioned on the upper edge of the outer air intakes on the Cayenne, the Cayenne Diesel, the Cayenne S, and the Cayenne S Hybrid. Again to provide a clear contrast, the Cayenne Turbo stands out clearly through its sidelights extending into the outer air intakes as well as the four LED spots providing the daytime light function in the main headlights.
Side view: long, sleek and dynamic
Seen from the side, the new generation of the Porsche Cayenne stands out particularly through its long, sleek and dynamic look. The new design of the car emphasises above all the long and stretched engine compartment lid as well as the flat rear roof pillar with its dynamic sweep towards the rear of the car.
Extending far to the front, the engine compartment lid is reminiscent of Porsche’s racing cars back in the ’60s, clearly emphasising the superior power and performance of the Cayenne and thus creating a direct link between the engine at the front and the road beneath the car. In all, the new design line gives the new Cayenne a truly sweeping, dynamic and coupé-like character.
The particularly slender D-pillar and the new window graphics at the rear create a fast, sweeping motion from the roofline to the clearly contoured and accentuated rear end of the new Porsche Cayenne, thus contributing to the vehicle’s compact and dynamic appearance. The design line of the wings extends above the rear light clusters all the way to the rear end of the car. Completely new in their design and featuring LED technology, the rear light clusters now stretch further to the front and, through their tapered design, emphasise the sheer length of the car.
The window graphics make a decisive contribution to the new look of the Cayenne, the windows following in their shape the elegant roofline all the way from the A-pillar to the D-pillar rapidly sweeping out at the rear.
The clearly contoured wings and doors, in turn, give even greater emphasis to the wheel arches. And last but not least, a discreet model designation in chrome look at the side on the front wings highlights the Cayenne Diesel and the Cayenne S Hybrid.
Rear view: powerful and with broad shoulders
The rear-end design of the new Porsche Cayenne now also shows even more clearly that these are fully-fledged members of the Porsche family. This is ensured by the D-pillars tapering out at a lower angle at the rear, the consistent implementation of emotional design with round design lines reminiscent of Porsche’s sports cars, and horizontal styling elements such as the chrome trim bar at the transition point from the tailgate to the rear bumper.
The clearly contoured rear wings emphasise the car’s proximity to the road also at the rear, again giving the new Cayenne a powerful stance on its wheels. The wings flow further back to the rear, enhancing the typical shoulder effect so characteristic of every Porsche. Positioned far to the outside at the rear, the rear light clusters take up the dynamic joint from the side, extending this sweeping line through the tailgate into the roof spoiler.
The newly designed tailpipes form the rear end of the car in visual terms – two rectangular single tailpipes on the Cayenne, the Cayenne Diesel, the Cayenne S, and the Cayenne S Hybrid, while the Cayenne Turbo comes with two round dual tailpipes.
In addition to their model designation, all new versions of the Porsche Cayenne come with Porsche’s new aluminium colour brand name above the numberplate.
Light weight at its best: the bodyshell
Developing and building the new bodyshell of the Cayenne, Porsche’s engineers have taken a big step in lightweight construction: Although the new generation is longer and even more stable than before, the weight of the body-in-white is down dramatically, the body of the new Cayenne losing no less than 111 kilos or 245 lb in weight and therefore making the largest single contribution to the significant reduction of weight on the new generation. The doors, engine compartment and rear lid alone are 39 kilos or 86 lb lighter than before. And last but not least, the wings made of aluminium also help to reduce the car’s weight.
Despite the higher standard of safety offered by the new model, both driving dynamics and fuel economy have been improved consistently. The driver and passengers in the new Porsche Cayenne are protected by driver and front passenger airbags, curtain airbags and, on the front seats, side airbags in the event of an accident – naturally with all these features coming as standard. And to provide the final touch, side airbags are also available at the rear as an option.
Consistent development of lightweight steel construction by Porsche once again plays a key role on the new Cayenne, offering even greater stiffness than on the former model.
In the event of a crash, the forces acting on the car are spread out in a defined process on the longitudinal and crossbar structures at the front and rear, multi-phase steel ensuring a high standard of strength, clear deformability and optimum uptake of energy. At the same time reinforcements made of ultra-high-strength heat-moulded steel protect the occupants in a collision from the side, surrounding the passenger cell like a cage and therefore, through their extreme stability, making a decisive contribution in retaining the shape of the passenger cell and maintaining the high level of occupant safety.
The level of safety has also been improved once again on the roof structure through the use of heat-moulded steel.
All four doors are pressed lightweight steel structures with extra-strong, fully integrated steel profiles improving side impact protection. As a result of the car’s constructive lightweight engineering, the rear lid, thanks to the use of aluminium, is more than 50 per cent lighter than on the previous model. A further advantage of this lower weight is greater ease in opening and closing the lid, which now requires only a minimum effort.
All models in the Cayenne range come as an option with an automatic tailgate. Apart from the reduction of weight, great significance was given in developing this new tailgate to the improvement of the opening process, which is now smoother and more consistent than ever before. The new system uses electrical spindle drive on both sides supported by a coil spring. To open the rear lid, the driver has no less than three options: pressing the switch inside the car, opening the lid by remote control on the key, or using the button on the rear lid.
To close the rear lid, all the driver has to do is press the button inside the lid. The height to which the rear lid opens up, finally, may be adjusted individually at the touch of a button to the height of the ceiling, for example in your garage.
All models in the Cayenne range come as standard with tinted sun insulating glass all round, a grey stripe in the windscreen and hydrophobic coated door side windows at the front. These windows come with a coating based on nanotechnology, ensuring that the windows will be far less contaminated in rain and weather in the interest of better visibility.
A heated windscreen is available on all new models in the Porsche Cayenne range for the first time. Available in combination with all glass options, the windscreen will not mist over and will quickly de-ice in winter even under extreme conditions.
Sliding or Panorama roof as an option
An electrical sliding/vent roof made of glass or a Panorama roof system are both available as options on the new Cayenne. With its glass surface of 0.39 square metres or 4.2 square feet, the electrical sliding/vent roof is made of tinted single-layer security glass with a manual roof lining and comfort closing. The electrical sliding/vent roof is controlled by means of a switch on the roof console.
Likewise available at extra cost, the Panorama roof system, measuring approximately 1.4 square metres or 15.1 square feet, is almost four times the size of the sliding/vent roof, with its glass area extending all the way over the rear seats.
The Panorama roof is made up of two glass elements complete with a wind deflector, with the front element moving back over the rear unit.
To maintain the same level of headroom within the interior, all elements crucial to the space available, such as the guide rails and the drive, motor have been optimised also for minimum dimensions. At the same time the new structure allows a reduction in weight by more than 13 kg or 29 lb compared with the former system.
Even when closed the Panorama roof provides a wonderful panoramic view thanks to its transparent area 30 per cent larger than on the former model, giving the occupants a unique feeling of space and roominess. When opened the roof creates an ample opening of more than one square metre and, as a result, a unique feeling of space and grace on the road.
Like the electrical sliding/vent roof, the Panorama roof is controlled by a switch in the roof console. To keep out excessive sunglare, finally, the Panorama roof system comes not only with highly tinted glass, but also a sunblind likewise opening and closing electrically by pressing a button in the roof console.
A high-quality roof railing made of aluminium and fully integrated in the car’s design is available as an option. The roof railing comes with three roof protection bars, which are dropped on all models with the Panorama roof.
The roof railing provides the foundation for the roof transport system available as an option on all versions of the Cayenne. Maximum roofload on the new model is 100 kg or 220 lb.
All models in the Porsche Cayenne range are prepared for fitting a trailer towbar as subsequent equipment. As an option the Cayenne, Cayenne Diesel, Cayenne S, and Cayenne Turbo come with a towbar complete with a removable ball head. Maximum towing load is 3.5 tonnes, with a maximum load on the Cayenne with manual gearbox of 2.7 tonnes.
An electrically retracting towbar is also available as an option, in which case the user is able to fold the ball head on the towbar in and out electrically at the touch of a button. When folded up, the electrically retractable towbar disappears completely beneath the rear end of the car.
The button for folding the towbar in and out is positioned in the right side panel of the luggage compartment.
The Cayenne S Hybrid is available exclusively with the electrically operated towbar.
Intelligent headlights: Porsche Dynamic Light System
The Porsche Dynamic Light System (PDLS) is a further development of the xenon light system used so far. It features both dynamic and static bending lights as well as – for the first time in the Cayenne – speed-related headlight control with separate modes for country roads, for the Autobahn, and for bad weather.
Compared with the basic setting on the low-beam headlights, the country road mode offers a longer range on the left-hand side and a broader light beam, which adjusts accordingly at higher speeds, moving further to the front and improving the driver’s visibility without dazzling oncoming traffic.
The Autobahn light mode is activated as of 130 km/h or 80 mph, increasing headlight range accordingly. The poor weather light mode, finally, is activated as soon as the driver switches on the foglamps and reduces any self-dazzling effect under difficult conditions such as fog or snowfall.
To provide this effect, the low-beam headlights are spread out over a broader footprint and the left headlight adjusts the light/dark border horizontally to reduce the range of the light beam. A further feature is that the left-hand headlight swivels to the left in order to reduce any self-dazzling effect.
The bad weather light function is available up to a speed of 70 km/h or 43 mph.
PDLS is made up of a swivelling PDLS module for the dynamic bending lights and headlight range control, using a projection system to provide the functions required. The module as such comprises a rotating cylinder with various contours modifying the light/shade limit as well as a lens. Using the roller and changing light intensity, the bi-xenon headlights are able to provide the various light modes required.
PDLS is supplemented by static bend lights. In combination with the normal xenon high beams already providing particularly effective illumination in front of the car through the particular position of the roller with the lens fully open and with an increase in light inten sity for particularly effective illumination, PDLS also adds the halogen high-beam light function.
Over and above all these features, all models in the Porsche Cayenne range come in addition with LED direction indicators and LED positioning lights at the front. With the exception of the Cayenne Turbo, the front lights also offer the daytime light function in LED technology. On the Cayenne Turbo the daytime driving lights each incorporate four LED spots in the main headlights, while the positioning lights are positioned around the direction indicators.
PDLS comes as standard in the Porsche Cayenne Turbo. The other models are equipped with halogen headlights in projection technology and are available with PDLS as an option.
Sophisticated and Functional
The new Cayenne stands out clearly as a genuine Porsche right from the start – also within the interior.
New in its design and configuration, the interior with its demanding architecture clearly reflects the objective to combine greater flexibility with enhanced everyday driving qualities. Functionality, ergonomics and superior comfort for up to five occupants were the essential points from the start in designing the interior.
A particular eye-catcher is the centre console rising up to the front with its protruding switches and buttons giving the interior the character of a genuine cockpit.
Through their seating position and the new, exciting design of the centre console and the instrument panel, the front passengers are integrated even more into the car, enjoying an even more sporting feeling on their seats. A striking design element on the Cayenne is the typical, re-styled grab handles on the centre console now to be found on all four doors. The buttons for the various functions of the car are positioned in sensible groups to the left and right of the gearshift or selector lever, allowing fast and intuitive control without having to spend a long time looking for specific functions in complicated sub-menus.
This superior convenience and ease of control is supported by the large seven-inch TFT touchscreen positioned in the middle of the centre console.
The dashboard as well as the instrument panel come in brand-new design again expressing that DNA so typical of a Porsche, for example through five circular dials and the rev counter positioned exactly in the middle.
Even in standard trim, the Cayenne, Cayenne Diesel, Cayenne S, and Cayenne S Hybrid meet the greatest demands within the interior. The new surface structure around the dashboard and the doors, for example, clearly upgrades the interior in its qualities and appeal.
To ensure a pleasant touch and sophisticated looks, many surfaces within the Cayenne come as standard in tanned leather. The wide range of interior options, in turn, allows the customer to create his or her “personal” Cayenne according to his individual taste. Leather upholstery in the same colour of the car featuring a smooth surface is standard on the Cayenne Turbo and comes as an option on all other models.
Choosing optional leather upholstery in twin-tone finish, the customer will receive interior leather in two contrasting colours creating a sporting and elegant ambience to the last detail.
Leather upholstery in natural leather comes with the same features and surface coverage as leather upholstery in regular body colour, but uses carefully tanned leather in contrast to the regular smooth leather finish. Thanks to the specific tanning process applied, the leather retains its original grain and natural features, at the same time giving the interior a particular ambience.
Leather upholstery in natural leather is also available with a twin-tone finish and carefully creased leather comes as yet a further option.
All versions of the Porsche Cayenne come as standard with a three-spoke steering wheel two centimetres smaller in diameter than on the former model. On all steering wheels the grab points are finished in smooth leather in the standard colour of the car.
A three-spoke sports steering wheel complete with gearshift paddles and a three-spoke multifunction steering wheel are both available as an option, as is special heating of the steering wheel already provided as an option in the past.
New seats with a variable rear seat bench
The seats have been completely updated for the new Cayenne, offering all passengers greater comfort and a lot more space at the rear thanks to the wheelbase extended by 40 millimetres or almost 1.6″.
The Porsche Cayenne comes with five seats, two single seats at the front and a rear seat bench with three seats. The headrests are individually adjustable both at the front and on the two outer seats at the rear.
The rear seat backrests may now fold down separately in a 40 : 20 : 40 split, while the rear seat bench as such is 40 : 60 and may be moved to-and-fro 160 millimetres or 6.3″. The angle of the rear seat backrests, in turn, can be adjusted in three stages by up to 6°.
The comfort seats at the front with electrical eight-way adjustment featured as standard on the Cayenne, the Cayenne Diesel, the Cayenne S, and the Cayenne S Hybrid offer a wide range of adjustment options for seat height and angle, backrest angle and the fore-and-aft position of the seats. The seats are extremely comfortable, offering not only good side support, but also, through their wide range of adjustment, excellent body fit as well as grandtouring comfort truly excellent under all conditions.
The Driver Memory Package is available as an option on the Cayenne, the Cayenne Diesel, the Cayenne S, and the Cayenne S Hybrid, enabling the occupant to save his or her personal settings. The optional Comfort Memory Package for the first time offers fore-and-aft adjustment of seat bottom length, a four-way lumbar support for the driver and front passenger, an electrically adjustable steering column, and surround lights integrated in the exterior mirror housing.
Adaptive Sports Seats with a Comfort Memory Package adjusting to 18 different positions are available for optimum side support under all conditions. Featured as standard on the Cayenne Turbo, these excellent seats are optional on the other models.
With amenities such as adjustable air cushions in the side supports with individual filling and adjustment, the Adaptive Sports Seats adjust precisely to the driver’s individual contours, thus offering optimum side support even under very sporting and dynamic conditions.
The manually adjustable rear seat bench significantly enhances the everyday driving qualities of the new Porsche Cayenne. Adjusting up to 160 millimetres/6.3″ fore-and-aft, the rear seat bench also comes as standard with a through-loading function provided by the separately folding centre backrest.
Without requiring the passengers to remove the headrests, the backrests on the outer seats may also be folded down separately.
Backrest adjustment with three separate settings likewise provides an even higher standard of comfort. Proceeding from the standard setting, the backrests may be set either 3° steeper or 3° lower separately of one another.
Heating and cooling: seat climate control
Seat heating is available on the front seats as an option, for the first time as a separate feature without steering wheel heating on the new Cayenne.
The seat heating system warms up not only the centre sections on the seat bottom and the backrest, but also the side elements.
Seat heating for the rear seats is likewise available as an option, with both features (seat heating front and rear) coming as standard on the Cayenne Turbo. In each case the heating system operates in three stages and is adjustable individually by means of switches on the centre console front and rear.
Seat heating in the front seats may be further enhanced by seat ventilation as an additional option. Such active ventilation of the perforated seat and backrest centrepieces creates an air drag effect drawing in perspiration moisture then transported out of the seats by specially arranged air ducts.
Again, seat ventilation is individually adjustable in three separate stages.
Enhanced range of instruments and extra features on the Porsche Cayenne S Hybrid
Over and above the wide range of instruments already featured in the past, the new Cayenne comes with a 4.8-inch high-resolution TFT Colour Display in the instrument cluster, integrated in the second tube from the right. To control the Display, the driver uses either the righthand lever on the steering column or the right-hand rotating knob on the optional multifunction steering wheel.
The TFT Colour Display is able to present a wide range of information on the car’s settings, the audio system, the telephone, navigation unit, map presentation, trip information, tyre pressure control, and information on the cruise control.
The instrument cluster in the Porsche Cayenne S Hybrid differs from that in the other models through a number of technical features underlining the unique concept of this very special model and offering the driver an experience of the innovative hybrid drive system also through the instruments in the car. The centre tube features a “Ready” display in addition to the rev counter showing the driver when turning the key in the lock that the hybrid drive unit is in a position to drive the car under electric power alone. The “E-Power Meter” in the left-hand tube is an analogue power and performance display informing the driver in real time of the current power status of the electric motor. The “Power” indicator shows the power required for driving the car on electric power alone and when both drive units work together in the boosting mode. The “Charge” display, finally, presents the output of the electric motor acting as a generator in the recuperation phase (Brake Energy Regeneration).
The TFT Display in the instrument cluster presents the interaction of the two drive units as well as the current status of hybrid drive for the driver’s information. The flow of energy is also shown here in real time by a coloured arrow symbol indicating the respective direction of flow, giving the driver feedback on current driving conditions. The charge status of the traction battery is also presented as additional information.
Available as an option, PCM Porsche Communication Management presents all hybrid-specific driving conditions in a detailed graphic image of the vehicle, naturally in real time. This animated graphic informs the driver of the current operating status of the hybrid drive system by presenting the flow of energy between the various hybrid drive components and the charge status of the traction battery. This clear visualisation informs the driver of his particular style of driving and allows him to follow a specific driving pattern in the interest of greater fuel economy.
The driver is also able to activate another graphic in the PCM unit providing a statistical evaluation of driving conditions. A clear bar diagram presents the share of electric hybrid motoring in per cent of the overall time spent on the road. The operating conditions taken into account in this statistical evaluation and in the overall calculation of hybrid motoring in the electric mode are Auto Start Stop, recuperation, sailing, and all-electric motoring.
Automatic air conditioning featured as standard
All models in the Cayenne range come as standard with two-zone automatic air conditioning. The new Cayenne thus enables the driver and front passenger to control the temperature and air distribution and, for the first time, air volume fully automatically in a separate process on either side. The functions required may also be set manually by a central control unit on the centre console.
Equipped with a larger condenser and using an additional heat exchanger in the cooling circuit, the new Cayenne offers a far higher level of cooling capacity, with the passenger compartment cooling down even faster particularly in hot summer weather. At the same time the heat exchanger integrated in the cooling circuit reduces the consumption of fuel.
As an option all models in the range, with the exception of the Porsche Cayenne S Hybrid, are available with four-zone automatic air conditioning instead of the two-zone automatic air conditioning featured as standard. The big advantage of four-zone air conditioning is that it allows individual climate control also on the rear seats.
This rear seat climate control function in provided by a separate rear air conditioner with its own condenser and heat exchanger operating independently of the automatic air conditioning at the front and controlled by a separate unit in the centre console.
Variable luggage compartment with numerous options
Offering a volume of 670 litres (580 litres on the Cayenne S Hybrid), the luggage compartment in the new Cayenne is fully suited also for long trips with the driver and four passengers. The rear seats folding down either completely in split sections increase luggage compartment capacity when required in steps up to 1,780 litres (1,690 litres on the Cayenne S Hybrid), offering ample capacity for transporting even particularly bulky objects such as several bicycles all together.
As long as the seats have not been folded down, the distance between the tailgate and the rear seat bench adjusting fore-and-aft is between 98.7 and 114.7 centimetres (38.9 – 45.2″), depending on the position of the seats. With the rear seats folded down, on the other hand, the luggage compartment in the Porsche Cayenne is 116.6 centimetres/45.9″ wide at its narrowest point, and 165.7 centimetres/65.2″ long from the tailgate to the front seats at the shortest point.
Available as an option, the Luggage Management System facilitates the individual subdi vision of the luggage compartment, comprising features such an integrated rail system, a telescopic bar, and a luggage compartment partition net.
Cruise control as an option also with distance control by radar
The new Cayenne comes as standard with automatic cruise control serving to enhance motoring comfort particularly on long distances by automatically retaining the travel speed desired within a range from 30 – 210 km/h (20 – 130 mph). Cruise control with an additional distance function is available as an option in conjunction with Tiptronic S. Using radar sensors, this highly sophisticated control unit monitors the distance from the vehicle ahead, automatically keeps the right distance and applies the brakes when necessary at a brake pressure of up to 3.5 metres/sec2 until the car comes to a complete stop.
To offer the driver extra comfort, the system switches to a crawl motion prior to coming to a complete halt, thus avoiding the need to stop completely for only a brief instant behind another vehicle and keeping the Cayenne in motion at a slow but smooth pace.
Incorporating special functions such as an overtaking aid, cornering speed control and distance warning, cruise control with its special distance function offers a wide range of additional benefits. As soon as the driver sets the direction indicator, for example, the cruise control function is interrupted and cruise control automatically accelerates to the desired speed originally set by the driver.
The cornering speed function, in turn, is activated when taking a bend as of a certain level of lateral acceleration, thus avoiding undue acceleration for example when driving in a roundabout. Then, after leaving the bend, the system seeks to once again return the car to the desired speed selected in advance.
The various functions of cruise control with a proximity warning may be presented if desired in the instrument cluster colour display, together with a wide range of additional information such as the required and actual distance from the vehicle ahead, the desired speed speci fied by the driver, or the speed of the vehicle ahead.
To ensure a high standard of active safety, his range of functions is further enlarged when necessary: Whenever the system “sees” that the car is too close to the vehicle ahead it enhances the brake standby function by pre-loading the brake system in order to shorten the stopping distance if required. Should the car approach a vehicle ahead too quickly, on the other hand, the system gives the driver both an optical and an acoustic warning and for the first time touches the brakes as an additional signal to the driver, even if the proximity cruise control warning has been deactivated.
Even when cruise control with its distance function is deactivated, the distance warning function warns the driver should he come too close to a vehicle ahead, with a yellow warning triangle coming on for this purpose in the instrument cluster.
The various cruise control functions may be presented in the instrument cluster colour display, together with a wide range of information such as the desired and actual distance from the vehicle ahead, the desired speed, or the speed of the vehicle driving in front.
Lane Change Assistant for extra safety and comfort
The optional Lane Change Assistant (LCA) uses two radar sensors in the rear bumper to monitor the lanes to the left and right of the vehicle up to 70 metres (230 feet) back, including the blind angle. This specific function means a significant improvement of both safety and comfort particularly on the Autobahn, with the Lane Change Assistant operating throughout a broad speed range from 30 – 250 km/h (20 – 155 mph).
Should there be another vehicle in the driver’s blind angle or if another vehicle is rapidly approaching from behind, the driver is warned by four LEDs in the inside of the exterior mirror. This warning comes in two stages: As long as the driver has not set the direction indicator, the LED warning remains in the background, informing the driver without any further warning that there is a vehicle (or vehicles) on the adjacent tracks up to a distance of 55 metres or 180 feet. Once the driver, in such a situation, sets the direction indicator in order to change lanes, the LEDs will flash on and off intensely to warn him more clearly of a vehicle approaching from behind.
As in the past, all models in the range are available with a Parking Assistant featuring optical and acoustic control functions. This sophisticated system comes as standard on the Cayenne Turbo and may in all cases be further enhanced by an optional back-up camera.
Audio entertainment for every need
The Porsche Cayenne is available with the latest generation of audio and communication systems already featured on the Panamera. These systems meet the highest technical standards and have been optimised in the meantime for supreme ease of control. Now measuring seven inches across, the colour display of the CDR-31 audio system (standard on the Cayenne, Cayenne Diesel, Cayenne S, and Cayenne S Hybrid) as well as the colour display featured in PCM Porsche Communication Management (standard on the Cayenne Turbo) are positioned higher up on the dashboard for enhanced ergonomics and allow quick and simple control through their touchscreen function.
The range of customisation offered by the new Cayenne in terms of both audio and communication systems has been further enhanced over the former model. Like the Panamera, the new Cayenne is available not only with a BOSE®, but also with a Burmester® High-End Surround Sound System. The universal audio interface has also been modified, now allowing various iPod® and iPhone® models to be connected by the USB stick to the audio system. And as yet a further feature, the telephone module is now compatible with an even larger range of mobile phones.
The BOSE® Surround Sound System featured as standard in the Porsche Cayenne Turbo and optional on the other models comprises no less than 14 loudspeakers, a 200-Watt active subwoofer with a Class-D terminal and loudspeaker membranes measuring 200 millimetres/7.9″ in diameter, as well as nine amplifier channels to provide a truly impressive experience in sound on overall output of 585 Watt.
The Burmester® High-End Surround Sound System already well-known from the Panamera and praised by experts and customers everywhere has been specially modified for the new Cayenne, offering truly unique output and quality of sound confirmed by the system’s performance data: 16 loudspeakers with individual adjustment, a 300-W active subwoofer complete with a Class-D terminal and loudspeaker membranes measuring 250 millimetres/9.8″ in diameter, 16 amplifier channels, and overall output of more than 1,000 Watt. The acoustically effective overall membrane area in this case is more than 2,400 square centimetres.
