The Porsche 911 GT1 was a car designed for competition in the GT1 class of sportscar racing, which also required a street legal version for homologation purposes. The limited-production street-legal version was labeled the 911 GT1 Straßenversion (Street version).

History

With the revival of international sportscar racing in the mid-1990s, though the BPR Global GT Series (which then morphed in to the FIA GT Championship) Porsche expressed interest in returning to top level sportscar racing and went about developing its competitor for the GT1 category. Cars in this category were previously heavily modified versions of road cars, usually supercars such as the McLaren F1 and Ferrari F40, but when the 911 GT1 was uneveiled in 1996 Porsche had exploited the rule book to the full and stunned the sportscar fraternity. Rather than develop a race version of one of their road going models, what they created was effectively a purpose built sports-prototype, but in order to comply with regulations a street legal version was created, 911 GT1Straßenversion - literally a road-going racing car.

911 GT1

In spite of its 911 moniker the car actually had very little in common with the 911 of the time, however its frontal chassis was shared with the then (993) 911, while the rear of the car was derived from the Porsche 962, including its water-cooled, twin-turbocharged and intercooled, four valve per cylinder flat-six engine which was arranged in a mid-mounted position, compared to the rear engined layout of a coventional 911. The engine was making about 600 PS (441 kW; 592 hp). In comparison, the 993 generation 911 GT2, which was otherwise the company's highest-performance vehicle, used an air-cooled engine with only two valves per cylinder.

The 1996 version of the 911 GT1

The new vehicle was an outright success at Le Mans, winning the GT1 class at its debut race, although it lost the overall victory to Joest Racing's Porsche WSC-95 prototype, still a success in that this vehicle used a Porsche powerplant.

The 911 GT1 made its debut in the BPR Global GT Series (the FIA championship's predecessor) at the Brands Hatch 4 hours, where Hans-Joachim Stuck and Thierry Boutsen won comfortably, although they were racing as an invited entry and were thus ineligible for points. They followed up by winning at Spa and Ralph Kelleners and Emmanuel Collard triumphed for the factory team at Zhuhai.

The '96 GT1 had around 600 PS (441 kW) and was clocked at a top speed of exactly 330 km/h (205 mph) on the legendary Mulsanne Straight in the practice sessions of the 1996 Le Mans 24 Hours Race (presumably on a low downforce setup).

911 GT1 Evo

In 1997, the new Mercedes-Benz CLK-GTR was successful in the new FIA GT Championship that replaced the BPR, as it was developed for racing. Mercedes did not enter Le Mans yet with their new car, though. The Porsche did not prove to be as fast in the FIA series, and failed to win a single race, first against the McLaren F1 GTR, and then against the new CLK-GTR.

Towards the end of the 1996 season Porsche made revisions to the 911 GT1 in preparation for the 1997 season. The front end of the car was revised including new bodywork which featured headlamps that previewed the all-new 2nd generation (996) Porsche 911 which would appear in 1997. The revised car was known as the 911 GT1 Evo (or Evolution). As far as performance goes, the car had the same 600 PS (441 kW; 592 hp) turbo-charged engine, but new aerodynamics on the car allowed the '97 car to be considerably faster than the 1996 model - acceleration was better, although the top speed was still around 330 km/h (205 mph) on the La Sarthe Circuit (in the race, the GT1-Evo reached 326 km/h). However, the works cars suffered from reliability problems and did not last the full race distance; a privately entered 1996 specification GT1 managed 5th overall and third in its class, but was beaten by the BMW-backed and powered McLaren F1 GTRs.

911 GT1-98

For the 1998 season Porsche developed an all-new car, the 911 GT1-98. Designed to match the also new Toyota GT-One and Mercedes-Benz CLK-GTR, the 911 GT1-98 featured bodywork which bore more of a resemblance to traditional sports-prototypes than the previous 2 models while a new sequential gearbox was installed. As per the regulations a street-legal version of the 911 GT1-98 was spawned, but it is believed that only one variant was produced which was still sufficient to satisfy the regulations.

During the 1998 FIA International GT season the 911 GT1-98 struggled to match the pace of the Mercedes, which also were improved, with the main reason being down to the air-restrictor rules being which were regarded as unfavourable to the turbo engine (the Merecedes being naturally aspirated). The Michelin tyres of the factory team and especially the Pirelli of the private Zakspeed team were also considered inferior to the Bridgestone of Mercedes.

At the 1998 Le Mans however, it was a different story. The BMW V12 LM retired with wheel bearing trouble, and the Mercedes CLK-LM vehicles had oil pump troubles in the new V8 engines that replaced the former V12. The Toyota GT-One, which was considered to be the fastest car, also suffered gearbox reliability problems.

The 911 GT1-98, despite being slower than the Toyota or the Mercedes, fulfilled Porsche's slim hopes, taking both first and second place overall thanks to reliability, giving Porsche its record-breaking 16th overall win at Le Mans, more than any other manufacturer in history.

At Petit Le Mans race in Road Atlanta, the 911 GT1 '98 of Yannick Dalmas made a spectacular backward flip and landed rear first before hitting the side barriers, as did the BMW V12 LMR at the same race in 2000, and most infamously the Mercedes-Benz CLR at Le Mans in 1999.

The GT1 '98 was set up with higher downforce in the race than the previous two years, which reduced its race maximum speed to 310 km/h (193 mph). However, in the 1998 Le Mans 24 Hours test days, the car hit 330 km/h (205 mph) on the Mulsanne Straight on a lower downforce setup.

1999

With Mercedes dominating FIA GT1 in 1998, all other entries including Porsche withdrew for 1999. The GT1 class was cancelled, and the FIA GT Championship was contested with GT2 cars. Porsche could have entered at Le Mans, but chose not to try to defend the win of '98 against new machines from other factories.

Champion Racing brought a 911 GT1 Evo to America to race in the American Le Mans Series, but was only allowed to do so as an LMP (Le Mans Prototypes) class entry, where it proved uncompetitive against actual prototypes such as the BMW V12 LMR.

Gunnar G-99

Following Champion's purchase of a 911 GT1 Evo for 1999, Gunnar Racing offered a custom race car to the team with intentions to race in 2000. The car, known as the Gunnar G-99, was a custom-built 911 GT1 with an open cockpit. The chassis was made from scratch yet remained nearly identical to the 911 GT1 mechanically, even using the bulk of the bodyparts. A large rollbar was put over the open cockpit to help protect the driver. A 3.6 litre flat-6 from a Porsche 911 GT3 was used in place of the standard 911 GT1 unit.

However, Champion would instead turn to buying a Lola B2K/10, so the Gunnar G-99 was temporarily abandoned. The car would resurface in the Rolex Sports Car Series in 2002, yet would not be allowed to race until it had a roof again. Therefore Gunnar Racing rebuilt the car with a near identical GT1 roof, and briefly competed in 2003. The car would take a best finish of second in class twice before being retired due to lack of funding.

Regulations for the GT1 category stipulated that to be eligible, a total of 25 cars must be built for road use. Porsche developed a fully road-legal version, dubbed "911 GT1Straßenversion", and delivered one in early 1996 to the German government for compliance testing, which it passed. The engine had to be slightly de-tuned to meet European emissions laws, although its 544 PS (400 kW; 537 hp) and dry weight of 1,150 kg (2,535 lb) proved to be more than adequate; the vehicle could accelerate to 100 km/h (62 mph) from a standstill in 3.9 seconds on its way to a top speed of 308 km/h (191 mph).

The Porsche 991 is the internal designation for the seventh generation Porsche 911 which was unveiled at the 2011 Frankfurt Motor Show on 15 September as the replacement for the 997. An initial release of photos and information was revealed by Porsche on 23 August 2011.

The current direct injection 3.8-litre flat-six engine from the Carrera S remains, with power increasing to 400 PS (294 kW; 395 hp). The Carrera engine is a 3.4-litre, producing 350 PS (257 kW; 345 hp). The car features an optional stop/start system and also electro-mechanical power steering. The car also features a new seven-speed manual gearbox, a first for a production car, along with the seven-speed PDK dual clutch transmission which was available in the 997.

Compared to the outgoing 997, the 991 wheelbase has increased by 100 mm (3.9 in) to 2,450 millimetres (96.5 in), with the overall length up by 70 mm (2.8 in) to 4,490 millimetres (176.8 in). A new transaxle was developed so that the rear wheels could be moved 3 inches backward in relation to the position of the engine, which significantly improves the weight distribution and cornering performance of the new 911. Due to the use of high-strength steels, aluminium and some composites the weight has been reduced by 45 kg (99.2 lb) to 1,470 kilograms (3,250 lb).

Images of the 991 were widely published on the internet on 18 August 2011, prior to the car's official debut. The photos revealed Porsche had taken an evolutionary design step, in keeping with the previous generation 997 and 996.

The Porsche 997 (Nine-Nine-Seven) is the internal designation for the Porsche 911 model manufactured and sold by German manufacturer Porsche between 2005 and 2011. Production of the Carrera and Carrera S coupés began in early 2005, all-wheel driveCarrera 4 and Carrera 4S versions began shipping in November 2005, Turbo and GT3 derivatives went on sale in late 2006 and the 911 GT2 in 2007. In addition to the coupe and cabriolet versions, Targa versions of the Carrera 4 and Carrera 4S were also available, which carry on with the "glass canopy" roof design used on all Targa 911s since the Type 993 Generation 911.

During 2009 Porsche made comprehensive changes to the 997 lineup which included small styling changes, increases in engine displacement across the board, the addition of direct injection and the introduction of the company's new "PDK" dual clutch transmission. As a result, the updated 997 models was faster, lighter and more fuel efficient than the outgoing versions and have somewhat better handling. In the case of the 997 Turbo, a comprehensively re-tuned all wheel drive system with an optional "torque vectoring" system was also a part of the upgrades package; in an October 2009 preliminary review, Car and Driver magazine estimated that when equipped with the PDK transmission, the updated Turbo should be capable of going from 0-60 mph in three seconds.

The 997 is the most commercially successful 911 of all time, having sold 100,000 units between its introduction in 2005 and July 2007. It has also received mostly positive reviews from the worldwide motoring press; even British motoring journalist Jeremy Clarkson, a known detractor of Porsche vehicles, noted that the 997 will "make love to your fingertips and stir your soul."

First generation

Design

While the exterior styling is slightly changed compared to the 996, it is again more evolution rather than revolution; typical of Porsche and the Carrera. Jeremy Clarkson has often voiced the opinion that Porsche has "the laziest design team in the world" due to the almost unnoticeable change in external appearance between the 997 and earlier models. The most notable difference between the 997 and the predecessor 996 is the return to circular headlights, like those of pre-996 Carreras, with separate indicator units. The interior has been almost entirely re-invented and all the controls are new; however, it is more reminiscent of classic 911 interiors than of the outgoing 996. The body in general remains low profile with a drag coefficient of 0.29 for the Carrera and .30 for the Carrera S.

The rear bodywork is a total of 88 mm (3.5 in) wider.

Performance

The base Carrera has essentially the same 3,596 cc (3.596 L; 219.4 cu in) flat-6 (Boxer) engine from Type 996 Carrera. The Carrera S uses a new 3,824 cc (3.824 L; 233.4 cu in) flat-6 engine. The X51 Powerkit is available for S, 4S, Targa models, which increases engine power.

According to testing carried out by several American automotive publications, the Turbo model can accelerate from 0 to 100 km/h (62 mph) in about 3.4 seconds with a Dual Clutch (PDK) and 3.5 seconds with the manual transmission. The Carrera S model is capable of going 0 to 60 mph (97 km/h) in 4.7 seconds, and carries a top speed of 300 km/h (190 mph), while the base Carrera model has 0 to 60 mph (97 km/h) acceleration in 4.8 seconds, with a top speed of 180 mph (290 km/h). Note, however, that these figures are conservative Porsche figures.

The viscous clutch all wheel drive system (997.1) sends between 5% and 40% of engine torque to the front wheels as needed.

Cabriolet

For the first time, development of the cabriolet version of the 997 led the design and engineering effort at Porsche with the coupe following. Porsche applied the logic that if you started with the more difficult cabriolet challenges (for chassis stiffness) the coupe version would simply be that much more rigid. Despite additional weight, the cabriolet versions attain nearly the same performance figures as their coupe counterparts. Even the rear tail comes up slightly higher on the cabriolets to compensate for differences in drag over the canvas top vs. the smoother coupe shape.

911 Club Coupe (2005)

It is a limited (50 units) version of 2006MY Carrera S coupé with X51 Powerkit commemorating the 50th anniversary of the Porsche Club of America (PCA).

The vehicle includes Azurro California-colored body (from Porsche 356), a vehicle identification number (VIN) which ends with the production number and special commemorative badging and door sills which adorn the interior, Sport Chrono Package Plus system, optional Porsche Ceramic Composite Brakes.

The car #1 was transferred to the Porsche Museum in Stuttgart, Germany and one PCA member won the car #50 in a sweepstakes drawing. The remaining 48 units were sold to randomly chosen U.S. and Canadian PCA members. After 2005-08-15, unsold units were made available to the general public.

The vehicle was unveiled in PCA's 50th Annual Porsche Parade in Hershey, Pa.

The vehicle has MSRP of $99,911 US and $145,911 CDN.

Targa

The Targa 4 and Targa 4S versions, like the Porsche 911 Targa of the 993 and 996 generations, are equipped with a glass roof and hatch. At any speed, the roof can be opened where it drops down an inch and slides a metre back underneath the hatch. As the roof weighs an additional 60 kg (132 lb) the suspension has been modified from Carrera models. When the glass roof is retracted, a small glass deflector above the windshield is raised to aid in aerodynamic stability.

Unlike previous versions of the Porsche 911 Targa, the Porsche 997 Targa 4 and Targa 4S have an all-wheel-drive drivetrain, hence the "4" in the name. The naming is to fit in with the naming trend of other Porsche models, namely the Carrera 4 and Carrera 4S, whose "4" in the names are also due to their all-wheel drive systems. Targa 4 models are slightly slower than the hard top Carrera models because of the heavier roof and all-wheel-drive drivetrain.

GT3

2006 Porsche 997 GT3 at the 2006 Geneva Motor Show

Porsche 997 GT3 RSR

The 997 GT3 model also debuted in Geneva in 2006. Like previous GT3 models, it is a way for Porsche to homologate aerodynamic features for racing, as well as a starting model for customer racing. The 997 GT3 was priced at US$106,000. The engine has the same displacement as the Turbo, but without turbocharger and uses a new variable intake system. The engine is rated at 415 PS (305 kW; 409 hp) and 405 N·m (299 lb·ft). It has an 8400 rpm redline which is the same as the 612 bhp (456 kW; 620 PS) Carrera GT's. The 3.6L dry-sump engine does not seem to share the rear main seal (RMS) problems of the earliest 3.6L/3.8L semi-dry-sump engines.

The GT3 body includes a special front bumper which increases cooling for the front-mounted radiators as well as a split spoiler at the rear. The GT3 also includes a special rear bumper and center tailpipes which draw heat away from the engine. It is lowered and rides on 30-series 305mm (12 in) tires on 19in (483mm) wheels. The car weighs 3075 lb (1395 kg).

The 997 GT3 is more driver-friendly than its predecessor, with "comfort" seats and the Porsche Communication Management system installed.

The special RS model came without most of these luxuries out to focus more on track-oriented driving (although the car is still road-legal). The package also included a full rollcage and carbon fiber seats to add to that race-car-for-the-road feel. The RS version was released in Europe in October 2006; the North American release was in March 2007. A racing version of the GT3 RS debuted in 2007, and it was called the 997 GT3 RSR.

The ratios on the six-speed transmission are more aggressive, allowing the GT3 to hit 60 mph (97 km/h) in 4.1 seconds, while the RS accomplishes the same in 4 flat. It will continue to 100 mph (160 km/h) in 9.2 seconds and has an ungoverned top speed of 310 km/h (190 mph).

Turbo

The 997 Turbo debuted in February 2006 at the Geneva Motor Show. It has a new front bumper with turn signals which are LED lights in a horizontal bar through the air intake. The fog lights are moved to the corners of the bumpers. Large air intakes in front of and behind the rear wheels are other obvious visual cues. The retractable rear wing is also one of the highlights, a feature which has been available on the 996 Turbo as well.

The engine is based on the rugged and very reliable 964/GT1 design rated 480 PS (350 kW; 470 hp) and 620 N·m (460 lb·ft). The turbocharger uses two-stage resonance intake system.

The BorgWarner's Variable Turbine Geometry (VTG), the first variable geometry turbines introduced to street Porsche 911 cars, uses guide vanes located in front of the turbine wheel that modulates inflow angle and speed. Variable geometry turbines were previously only available to diesel engined vehicles, but a similar approach was used successfully by Garrett starting in 1989 with the Shelby CSX that utilized a computer controlled variable nozzles instead.

The optional Sport Chrono package allows 911 Turbo to overboost for 10 seconds, increasing peak torque over a narrow rev range. According to official Porsche figures, it accelerates to 100 km/h (62 mph) in 3.9 seconds with the manual transmission, and 3.7 seconds with Tiptronic S transmission. It has also recorded a 60 mph (97 km/h) time of 3.2 seconds at the hands of US motoring publication Motor Trend, eclipsing all of its major competitors and even Porsche's own Carrera GT supercar. The 997 Turbo has an official top speed of 318 km/h (198 mph) and Jeremy Clarkson achieved an indicated speed of 322 km/h (200 mph) during his 2008 video special, Clarkson: Thriller.

Turbo Cabriolet

Porsche AG announced on May 7, 2007 that the 911 Turbo Cabriolet would go on sale in September 2007. The Porsche 997 Turbo Cabriolet is one of the fastest convertible sports cars in production. It is capable of similar top speeds and acceleration to the standard Porsche 997 Turbo Coupe. This is considered an astonishing feat because usually the convertible version of cars are much slower than the hardtop variant due to its slightly less stableaerodynamics associated with its soft roof, and its extra weight caused by the structural reinforcements made necessary by the absence of B and C pillars.

GT2

2007 Porsche 997 GT2

This is the most powerful and fastest road-going 911 GT2 ever to be sold to the public. The Porsche 996 911 GT2 was superseded by the 997-generation GT2, on sale since November 2007.

The 997 GT2 has a twin turbocharged 3.6 litre 6-cylinder engine based on 997 Turbo but Porsche achieved power increase through completely newly designed expansion intake manifold in which the distributor pipe is longer than in Turbo and the intake manifolds are shorter, a full titanium silencer is used also in GT2, even though the Porsche 911 (997) Carrera S variant has a slightly larger engine at 3.8 litres. Despite the power hike, Porsche claims fuel consumption at full throttle is improved by 15 percent compared with the Turbo.The GT2 accelerates in 3.6 seconds to 60 mph (97 km/h) and in 7.4 seconds to 100 mph (160 km/h) and has top speed of 329 km/h (204 mph). This makes it the first Porsche 911 GT2 to exceed the 200 mph (320 km/h) top speed after the 1998 Porsche 911 GT1 Race Version (which is not considered an actual Porsche 911 due to its mid-mounted engine and it only saw roads for homologation purposes). The Porsche 997 GT2 has a curb weight of 1,440 kg (3,200 lb). The only transmission choice is a 6-speed manual gearbox.

The GT2 is the first Porsche equipped with launch control.

Its appearance is slightly different from its sister-car, the Porsche 911 (997) Turbo, in a few ways. It does not have fog lights in the front bumper, it has a revised front lip, it has a larger rear wing (with two small air scoops on either side), and it has a different rear bumper (now featuring titanium exhaust pipes).

• Note: 0-60 mph acceleration times refer to the time taken to reach 60 miles per hour (96 kilometers per hour).
• Note: MSRP prices are set to the United States. In Europe prices are considerably higher and in some countries can even be double the American price.
• Note: wet-sump in all but GT3, GT3 RS, GT2 and Turbo versions which have a dry-sump, with an external oil reservoir and 7 pumps instead of only 3 in the less powerful versions. Porsche advertising incorrectly refers to wet-sump models as internal dry-sump. The system is just a baffled wet-sump which came about as a result of multiple engine failures in 996 models.

Second generation (2009-)

2009 Porsche 911 convertible (North America)

The 997 was revised in 2008 for the 2009 model year. The updated Porsche 911 (called 997 Gen II internally at Porsche) included following changes:

• A revised suspension
• A revised front bumper with larger air intakes
• Headlamps with newly optional dual HID projectors, a new LED taillamp shape, and LED turnsignals
• New direct injection engines with redesigned Porsche Sport Exhaust (PSE)
• Redesigned PCM system with optional touch-screen hard-drive navigation
• Tiptronic S option was replaced by PDK (Porsche Doppelkupplung) 7-speed dual clutch transmission.

Production began at late 2008. Pricing was increased from the 997, Gen I; the base Carrera model is set to start at US$ 76,300 for North American buyers.

Initially available models include coupe and cabriolet versions of Carrera, Carrera 4, Carrera S and Carrera 4S. The car was unveiled at theParis Auto Show in September 2008.

On June 6, 2008, these changes to the Porsche 911 were revealed on the Porsche website. The Turbo will have to wait until the Frankfurt show in September, thereafter the Turbo-based GT2 will be updated.

Targa (2009-present)

The updated Targa 4 and Targa 4S models were announced on the 28th of July 2008. The new Targa 4S has a top track speed of 185 mph and goes 0 to 60 in 4.7 seconds, while the Targa 4 is slower and has less mpg.

Turbo/Turbo Cabriolet (2009-)

Red Porsche 997 Turbo Cabrio (2010).

The facelifted version of the 997 Turbo, was unveiled at the 2009 Frankfurt Motor Show. It received a completely new 6-cylinder, 3.8 liter boxer engine delivering 500 hp (370 kW) with revised Borg-Warner variable turbine geometry (VTG) turbos. The 911 Turbo is now only available with a manual gearbox or the optional 7-speed PDK dual-clutch gearbox, which replaces the Tiptronic. With PDK and the also optional sport-chrono package, which includes the availability of a electronically controlled launch-control and an overboost-function for temporary increasing the turbo-pressure, Porsche claims the 911 turbo will go from 0 to 100 km/h (62 mph) in 3.4 seconds and reach a top-speed of 194 mph (312 km/h). However, several tests done by Auto-Magazines and unpartial testers have revealed that the 0–100 km/h acceleration-time is generally as low as 2.9 seconds. The model can now also be ordered with PTV, Porsche Torque Vectoring, which will brake the inner wheel to provide turning-torque through a curve. The looks of the facelifted model was left mostly untouched from the original 997 turbo, but there are subtle changes to the rear lights, now being LED-type, among changes to the front lamps. The rear exhaust outputs are now also "fatter" and the standard 19-inch (480 mm) wheels now have a new design. Thanks to revised dynamics the facelifted 997 can handle 1.3 g forces on a skid-pad according to Porsche. Its believed that the updated 997 Turbo was benchmarked against the Nissan GT-R in response to 3rd party testing between the 997 Turbo and the GT-R.

Models equipped with PDK also include an optional 3-spoke steering wheel with gearshift paddles as an alternative to the standard steering wheel with shift buttons.

Other optional equipment include Porsche Torque Vectoring (PTV).
