The 991 Turbo is introduced 40 years after the first 911 Turbo prototype. The power figure is now exactly twice the original car. Fortunately the weight is not up two times for the heaviest 911. The 991 Turbo is 50 kg / 110 lb heavier than was the 997 Turbo 3.8 with manual gearbox. Sad news for the enthusiasts: the 991 Turbo is not available with manual gearbox / good news for the older 911 Turbo owners: their cars will not lose their value.

The PDK has the coasting function which means the gearbox is declutched from the engine under free run (like shifting to neutral with manual gearbox), so the engine can drop its rpms to idling speed and save some fuel. Now if you brake under coasting (approaching traffic lights for example), the engine is turned off. The engine in the 991 Turbo is the same unit that was in the 997 Turbo 3.8, just that fine tuning has given it 15 additional kilowatts of power to retain the power/weight ratio of the older car.

The 991 Turbo has the rear axle steering. The first Porsche to have the rear axle steering was the 991 GT3. The system was designed for the 991 Turbo in first place, but as the last moment decision it was also incoroprated into the GT3 that was launched before the Turbo. At speeds of up to 50 kmh / 31 mph, the system steers the rear wheels into the opposite direction of the front wheels simplifying manouvering and parking. Between 50-80 kmh / 31-50 mph, the rear wheels are not steered and at speeds above 80 kmh / 50 mph, the system steers the rear wheels parallel to the front wheels, so the car can easily change lane going sideways.

More show, less go - the standard wheels are 20", which are too heavy for the best performance. But most of the customers want 20" wheels and Porsche gives them. Optionally available are the radar-controlled adaptive cruise control system, camera-based road sign and speed limit recognition.

PAA - Porsche Active Aerodynamics

Porsche developed an active aerodynamic system for the 991 Turbo. It consists of a sturdy, retractable three-stage front spoiler, whose segments can be pneumatically extended, and a deployable rear wing with 3 adjustable wing positions. So, the 991 Turbo has the front and rear spoilers configurable for fast cornering on the race track or for the top speed on the straight track. In the performance position, all segments of the front spoiler are fully extended, and they generate considerable downforce at the front axle. Similarly, the rear wing is extended to its maximum height with the greatest angle of attack generating maximum downforce at the rear axle.

Turbo S

Unlike before, Porsche offers the 991 Turbo S from the start of the production of the 991 Turbo. The unique features of the Turbo S are the GT3 mirrors, slightly different front spoiler grilles and interior features. As before, the Turbo S is a heavily equipped verson of the Turbo. The powerkit adds 29 KW of power and the following equipment, optional for the Turbo, are standard for the Turbo S: PDCC Porsche Dynamic Chassis Control hydraulic rollbar system, Sport Chrono (Launch control and 0.15 bar overboost functions), dynamic engine mounts, PCCB Porsche Ceramic Composite Brakes, central lock wheels, full led dynamic headlights, adaptive Sport Plus seats (18-way adjustment, memory) and seat backrest shells upholstered with leather. The 991 Turbo S laps the Nürburgring Nordschleife in 7:27, which is 3 seconds faster than the 991 GT3.

The heavy weight of the 991 Turbo and the omission of the manual gearbox makes the 991 S WLS a choice of the enthusiast - the power-to-weight ratio is only about 5% poorer than of the 991 Turbo, but the car is 200 kg / 440 lb lighter! Driving lighter car with less power is always more fun than driving a heavier car with more power.

It is nice that with the start of the 991 generation, the full model name is written on the car. In the older cars there was no '911' on the rear lid as the workers of Porsche AG were sure everybody knew it is 911, but they did not - as a consequence the people unfamiliar with Porsches (most of the people) call 911s (sometimes even the 911 Turbos) as Carreras.© Porsche

PDCC Porsche Dynamic Chassis Control is a hydraulic rollbar system. Before ordering it, take a testdrive in the standard car and in the PDCC-equipped 911 to understand if you feel any difference with your usual driving style. PDCC adds weight to the already heavy car. It was first introduced for the Cayenne to minimize body roll in cornering.© Porsche

2013 May 3: modest world premiere of the 991 Turbo
2013 September 10: 991 Turbo at the IAA Frankfurt Motor Show. For some reason they called it World Premiere, although the car was premiered in Moscow already 4 months ago. August Achleitner, the 911 product manager, talks about the fabulous car.

Aerokit

The package includes a distinctive front lip with side fins and a redesigned rear lid that has a fixed trailing edge with side winglets and a retractable rear wing with an adjustable angle of attack. The Aerokit can be ordered in the body colour or in black. In addition to the Aerokit add-ons, the standard side skirts and rear apron are also painted. In the black version, the air intake fins on the rear lid are also painted black. The total downforce at 300 km/h (186 mph) was increased from 9 to 26 kg in the top speed setting, and from 132 to 150 kg in the race track setting. To find a find a 300 km/h curve where you could use the addiitonal downforce is not an easy task. Also you would not want to increase downforce in the top speed setting as this would not help to achieve the top speed of the standard car. The Aerokit has always been more of an optical than a technical feature. The Porsche Aerokit is a wind-tunnel tested equipment and should always be preferred to the aftermarket kits, both because of the high speed safety and because of the residual value of the car.
