Along with its sibling Carrera 4, the 2005 Carrera 4S offered an all-wheel-drive system for the Porsche 911, but unlike the 4, the 4S gets the Carrera S' more powerful engine and it turns out that makes a big difference. The Carrera 4S was the more powerful and more dynamic version of the 997 Carrera 4 and an overall great sports car, especially for those in colder climates who need the safety of all-wheel traction. All rounder that fits nicely in the 911 lineup as perhaps the most practical.
The 911 Carrera Cabriolet is a true Porsche, from top to bottom. Like the rest of the range, the base Cabriolet got a mild refresh in terms of design that made it more modern and a little more crisp. The engine was upgraded, now with direct direction. The direct-injection 3.6-liter engine also got new air filters, a more free-flowing exhaust system, and reduced engine friction, making it more powerful than before. It has peak power of 339 bhp @ 6500 rpm and torque of 287 ft lbs @ 4400 rpm. The Carrera equipped with PDK covers 0-60 mph in 4.5 seconds and runs to a top speed of 179 mph.
Just a few months after the introduction of the 2004 911 (997 series), the convertible version was released. The release of the 997 911 Carrera Cabriolet marked the first time since 1977 that Porsche has given the convertible 911s the same engines as their Coupe siblings. The base 997 Carrera Cabriolet gets the 3.6-liter flat six-cylinder engine with 321 bhp and 273 ft lbs of torque. The convertible version for both Carrera and Carrera S was developed at the same time with the coupe.
Porsche refers to it as a new generation, even though the internal chassis code 997 remains unchanged. The 997.2 therefore is more of a mid-term facelift with some significant technological changes. Notably, the water-cooled flat-six engines get direct-injection technology, and a seven-speed, dual-clutch transmission replaces the previous five-speed Tiptronic automatic while the shift-it-yourself option remains a six-speed. Base Carrera coupe gets 339 bhp and 287 ft lbs and a 0.3 second faster 0 - 60 mph time of 4.5 seconds. Top speed now 179 mph. A nice update indeed.
The GTS was powered by the same engine that was installed under the limited-edition Porsche 911 Sport Classic, but it was offered with more options. It wasn't just a driver's car, it was built for the passenger as well, with more options for comfort. From the outside, the Carrera GTS Cabriolet featured the same wide body as the Carrera 4 Cabriolet. At the front, the sport design apron featured a black lip-spoiler underneath. The Carrera GTS logo was painted on the doors. In the back, the car was fitted with LED taillights and four-round exhaust pipes. The 19” light-alloy wheels with central log-nut were fitted as standard.
It's not often Porsche creates an all-new model in their 911 lineup. But the 997 Carrera GTS is just that. It's faster, more powerful and better looking than any other model in the Carrera family. However it's still a little less hardcore than the 911 GT3, and a lot cheaper than the 911 Turbo. The Porsche 911 Carrera GTS features a 3.8 litre flat-six engine which is tuned to develop 408 horsepower, that's 23 hp more than the Carrera S manages. Think of it as the perfectly optioned Carrera S for less money.
Like the rest of the range the Carrera S Cabriolet got a new 997.2 generation update. Not much is new on the outside, but the design refresh did give it a revised front bumper and larger air intakes, as well as by new large mirrors and the bright strip of LEDs below the headlights that serve as daytime running lights. Inside the car, there's a new communication management system, PCM 3.0 which includes a new touchscreen feature, is standard on all 2009 and onward 911s.
The Carrera S convertible was introduced to the market at the same time with the Carrera Cabriolet, a few months after their coupe-versions were unveiled. The convertible version for the Carrera S got reinforcements needed for the cabriolet built while the engineering was going on for the coupe, ensuring that the drop-top version was just as strong and performance-focused. It got the same engine as the Carrera S and made a case for itself as the best 911 of the range at the time.
In recognition of the 50th Anniversary of the Porsche Club of America (PCA), Porsche has created an exclusive 911 Carrera' S Coupe model featuring a distinctive exterior color, unique interior styling and commemorative touches, and a more powerful and higher performing engine. Limited to an exclusive production run of just 50 cars initially made available to eligible PCA members, the 911 Club Coupe was unveiled this past weekend at PCA's 50th Annual Porsche Parade in Hershey, Pa.
For the 997.2 generation, power from the 3.6-liter Carrera engine was increased to 345 hp while the Carrera S saw 385 horsepower from its 3.8-liter flat-six. Power was sent to the rear wheels via a standard manual box but for the first time, the 997.2 saw the introduction of the dual-clutch PDK as an option. The chassis remains largely unchanged, with slightly modified springs and dampers. The sports suspension is replaced with a variable, electronically controlled sports suspension based on the active PASM suspension. The sweet spot in the used car market at the moment.
The 997 Carrera S was the first step up in performance over the base 997 Carrera. Available over two distinct generations, the 997.1 Carrera S used a 3.8-liter engine producing 355hp – the available X51 Powerkit bumped that number to 376hp. From 2009 onwards, the 997.2 Carrera S offered 380hp from 3.8 liters. Besides a more powerful engine, it also comes standard with 19 inch wheels, larger brakes, and a lowered suspension with PASM.
The 2008 Porsche 997 GT2 is the most powerful and fastest roadgoing 911 Porsche has ever created. Power for the 997 GT2 comes from a 3.6 litre, twin-turbo, flat-6 cylinder engine which develops 530 bhp @ 6500 rpm, and a tire destroying 505 lb-ft of torque @ 2200 - 4500 rpm. most of the power gains have been achieved with changes to the turbo-charging system and the addition of a high-flow titanium exhaust system. Power is transferred to the rear wheels of through a 6-speed manual giving the car a 0-60 mph time of just 3.6 seconds and a 204 mph top speed.
Porsche’s 911 GT2 RS is a brute, a lightweight, twin-turbocharged, 620-hp bout of madness that stemmed from Stuttgart’s quest to see how high up the sports-car ladder the 911 could punch. It is the most serious roadgoing Porsche ever. The engine is a port-injected, 3.6-liter flat-six from the Le Mans–winning GT1 race car of the late ’90s, with a pair of variable-geometry turbochargers huffing a maximum of 23.2 psi of boost into the combustion chambers. The result is 620 hp at 6500 rpm and 516 lb-ft of torque at 2250. It gets a six-speed manual gearbox and rear-drive only. Yikes.
Even more powerful, faster and more dynamic than ever before, the updated 997 Porsche 911 GT3 (differentiated from the earlier with a new 997.2 designation) is about to prove its enhanced potential. The Porsche 911 GT3 now reaches an even higher standard in its two main qualities: power and driving dynamics. The naturally-aspirated six-cylinder now increased in size to 3.8 litres is 435 bhp (320 kW), up 20 bhp over the previous model. In particular, the flat-six power unit carefully upgraded for even more muscle and performance offers a significant increase in torque at medium engine speeds. Road performance is spectacular.
If the 996.1 911 GT3 was all about the engine, in the 997.1 completes the rest of the formula. The surgical clarity of its transmission, steering, brakes, pedal weights and heights, and overall chassis balance represented a clear step-change from its regular 997 911 siblings. But the engine was still the heart of the car, the water-cooled 3.6-liter flat-six boasting a new intake and a new exhaust compared with the 996 versions. Official output was 415 hp, though insiders admit some engines made close to 430 hp. Launched in 2006, today this is in many ways the sweet-spot GT3, way more affordable than the later 4.0.
The Porsche 997 GT3 Cup was a series of race cars created by Porsche to enter the Fédération Internationale de l’Automobile (FIA) Group GT3 racing class. Replacing the 996 GT3 Cup, the 997 Cup's 3.6 litre engine is rated at 294 kW (400 PS; 394 hp) and was mated to a six-speed sequential transmission. In 2009, the GT3 Cup received several 997.2 updates including a new 3.8 litre engine with an output of 331 kW (450 PS; 444 hp).
To a large extent, the 3.6-litre boxer engine is identical to the power unit used in the Porsche Mobil1 Supercup and the international Carrera Cup championships. Power output has increased by 20 horsepower to now 440 hp (324 kW) at 8,000 rpm. Maximum torque is up by ten Nm to 430 at 7,250 revs per minute. The power increase results from optimised engine electronics and a modified exhaust system. In contrast to the GT3 Cup, the body of the Cup S is not based on the road-going GT3 but on the GT3 RS.
Following the Porsche 911 GT3 Cup, Porsche AG, Stuttgart, is entering yet another racing car in the 2010 motorsport season: The 911 GT3 R will be raced in series based on the international FIA GT3 regulations, thus succeeding the 911 GT3 Cup S. The main focus in developing this new model was on even better drivability and even easier handling. The 911 GT3 R is powered by a four-litre six-cylinder boxer engine delivering maximum output of 480 bhp (353 kW) transmitted to the rear axle by a sequential six-speed dog gearbox.
During the Geneva Motor Show, a Porsche 911 GT3 R with innovative hybrid drive is making its debut. The innovative hybrid technology featured in the car has been developed especially for racing, standing out significantly in its configuration and components from conventional hybrid systems. In this case, electrical front axle drive with two electric motors developing 60 kW each supplements the 480-bhp four-litre flat-six at the rear of the 911 GT3 R Hybrid. Instead of batteries, an electrical flywheel power generator delivers energy to the electric motors.
Porsche 911 GT3 R Hybrid 2.0 (2011)
The Porsche 997 GT3 R Hybrid 2.0 is an update to the 997 GT3 R Hybrid. Compared to its predecessor, which debuted in 2010, the 2011 second-generation hybrid is 20 percent lighter and more efficient without any concession to lap times. While sharing the same paint scheme, the new vehicle is easily identified by its lack of intakes in front of each rear wheel - changes to engine cooling allowed the slats to be dropped and aerodynamic efficiency improved. It gets a traditional race-bred flat six engine. The GT3 R Hybrid has a completely independent second driveline in the front of the chassis, a clever and complex hybrid electric set up that rockets it from standstill to 60 mph in just 2.5 seconds.
Based on the already primal 997.2 GT3, the RS gets another 15 hp from the 3.8-liter flat-six for a total of 450, or more than 118 hp per liter. A racing machine tamed for street use, the GT3 RS is hardly just about horsepower. It gets a wider track, it weighs less, and it produces more downforce than the GT3. The only available transmission is a six-speed manual gearbox (with the ratios even shorter than the GT3). A racing machine tamed for street use, the GT3 RS also gets a wider track, it weighs less, and it produces more downforce than the GT3.
The 997 911 GT3 RS is an even lighter and more purist version of the 911 than the regular GT3. 20 kilograms lighter than the GT3 and equipped with a close-ratio six speed manual the GT3 RS gets to 60 mph 1/10th of a second faster than the GT3. The 911 GT3 RS is 44mm wider at the rear than the GT3. The wider track helps improve directional stability when cornering. Weight savings can be found throughout the car. The Clubsport version there is a bolted roll cage, a six-point harness for the driver and a built in fire extinguisher. 
This is the best 911 Porsche has ever made. The headline power figure and the ability to rev to 8,500 snare your attention, but the most staggering aspect of this engine is actually its tractability. Mid-range lunge is marvelous, even if the peak number of 339 pound-feet doesn't sound huge in the context of short gear ratios, lightweight, and a compact frontal area. In third gear, the way this thing flies between 4,500 and 8,500 rpm is scintillating. Plus, the utter progression of the delivery makes it vastly easier to take advantage of compared to the GT2's ridiculous turbo surge. This is one special car.
Porsche has announced the introduction of the new 2007 911 GT3 RSR (type 997) for the American Le Mans Series and other world GT racing venues. The latest version of the most successful racing sports car in history is based on the street production model 911 GT3 RS (model year 2007) and was launched in late 2006. The 911 GT3 RSR has wider rear fenders and rear track to improve performance capabilities over its predecessor. The car has also been developed to fit into the 1,225 kg class. The new car is built in accordance with the ACO LMGT2 Regulations and the FIA Article 257.
Paying homage to the first Porsche model that bore the name Speedster – the 356 Speedster – the production run for the new model is limited to 356 cars. The two-seater is significantly different from the other members of the 911 family. In the best tradition, the 60 millimetre lower, more raked windscreen, the flat contour of the sporty-look manual hood, and the characteristic double-bubble hardcover for the soft top define the striking profile of the new 911 Speedster. This makes the body of this rear-wheel drive with its 44 millimetre wider rear stand out even more.
The 997 Sport Classic is a limited edition version of the 997.2 Carrera S coupé inspired by the 1973 Carrera RS 2.7. The engine is rated at 413 PS (304 kW; 407 hp) and features a newly developed resonance intake manifold with 6 vacuum-controlled switching flaps. It includes a 6-speed manual transmission, double-dome roof (informally called double bubble roof), 44 mm (1.7 in) wider rear fenders, SportDesign front apron with a front spoiler and a fixed 'duck tail' rear wing. Only 256 were made.
