Porsche 911 GT2


The Porsche 911 GT2 is a high-performance, track-focused sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and since 2010 as the GT2 RS. It is based on the 911 Turbo, and uses a similar twin-turbocharged engine, but features numerous upgrades, including engine enhancements, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of an all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 is the most expensive and fastest model among the 911 lineup.

993 generation

The 993 GT2 was initially built in order to meet homologation requirements for GT2 class racing. Because the cars were built to meet the GT2 class regulations, the road cars were named accordingly. The 993 GT2 featured widened plastic fenders and a larger rear wing with air scoops in the struts for improved engine cooling. The 993 GT2's original engine generated a maximum power output of ; in 1998 it was upgraded to. 57 road cars were built.

    996 generation

In 1999, the 993 was replaced with the new 996 model. The new GT2 took two years to develop and during that time, Porsche decided to abandon the GT2 for motorsports use, instead concentrating on competing in Le Mans GT class racing with the new naturally aspirated 911 GT3.
Developed primarily as a road car in contrast to its predecessor, the new GT2 featured a twin-turbocharged version of the GT3's flat-six engine. It generated a maximum output of, which was later increased to. Like the 993 GT2, the body of the 996 GT2 differed significantly from those of other 996 variants; major differences included wider fenders, a more aggressively shaped nose, and a large rear wing.
According to road testing performed by Car and Driver magazine, the GT2 suffers from hardly any turbo lag. Despite a 10-millimeter reduction in ride height from the 911 Turbo, the drag coefficient is slightly higher — vs. the Turbo's 0.33 — due to the fixed rear wing.

    997 generation

The 996 GT2 was superseded by the 997 GT2 in 2007 after a brief hiatus, with cars arriving at dealerships in November 2007 after an official launch at the 62nd Frankfurt Motor Show.
The GT2's engine was based on the flat-6 engine as seen on the Turbo, but featured two variable geometry turbochargers. The engine generated a maximum power output of at 6,500 rpm and of torque at 2,200 rpm. The GT2 accelerated from 0 to in 3.6 seconds and on to in 10.6 seconds, and had a maximum top speed of. This made it the third Porsche production road car to exceed the barrier, with the exception of the 1998 911 GT1.
The American automotive magazine Motor Trend tested a 2008 Porsche 911 GT2 and achieved a acceleration time of 3.4 seconds, and a quarter mile time of 11.4 seconds at. The GT2 also recorded a braking distance from 60 to 0 mph of, and 1.10g of lateral grip.
The appearance of the 997 GT2 once again differed from its sister car, the 997 Turbo. It had a revised front lip, a newly designed rear wing with two small air inlets on either side, and a revised rear bumper featuring titanium exhaust pipes and shark fin outlets.
German Porsche test driver Walter Röhrl lapped the Nürburgring Nordschleife on a public day in 7 minutes, 32 seconds in the 997 GT2.
A total of 194 units were sold in the United States and 19 units in Canada.

    997 GT2 RS

On 4 May 2010, an RS variant was announced to German dealers in Leipzig. The engine in the GT2 RS generated a maximum power output of and of torque. The GT2 RS weighs less than the GT2, allowing for a top speed of and a acceleration time of 3.3 seconds.
According to the then Porsche Motorsports manager Andreas Preuninger, the RS was conceived around 2007 as a skunk-works effort. The 727 code number selected for the project corresponds to one of the Nissan GT-R's lap times around the Nürburgring's Nordschleife. When the dust settled, Porsche claimed that test driver Timo Kluck had supposedly eclipsed that target by an impressive nine seconds.
Porsche produced only 500 units of the 997 GT2 RS globally.

991 generation

The 991 GT2 RS was initially unveiled at the Xbox 2017 E3 briefing along with the announcement of the Forza Motorsport 7 video game where it was revealed as the cover car as well as being included as a playable vehicle.
The car was officially launched by Porsche at the 2017 Goodwood Festival of Speed along with the introduction of the 911 Turbo S Exclusive Series. The 991 GT2 RS is powered by a 3.8 L twin-turbocharged flat-6 engine that has a maximum power output of at 7,000 rpm and of torque, making it the most powerful production 911 variant ever built. Unlike the previous GT2 versions, this car is fitted with a 7-speed PDK transmission to handle the excessive torque produced from the engine. Porsche claims that the car will accelerate from in 2.7 seconds, and has a top speed of.
The car has a roof made of magnesium, front lid, front and rear wings and boot lid made of carbon-fibre, front and rear apron made of lightweight polyurethane, rear and side windows made of polycarbonate and an exhaust system made of titanium. Porsche claims that the car has a wet weight of.
A Weissach package option is available, which reduces weight by, courtesy of the additional use of carbon-fibre and titanium parts. This includes the roof, the anti-roll bars, and the coupling rods on both axles being made out of carbon-fibre, while the roll cage is made from titanium. The package also includes a set of magnesium wheels specially made by BBS. The car was available in the United States from early 2018.
A production run of 1,000 units was planned.
The production run of the GT2 RS was to end by February 2019 but four units were lost in transit to Brazil due to the sinking of the ship Grande America on which the cars were on board in March 2019. Porsche decided to restart production to reproduce the lost cars.
In late September 2017, the 911 GT2 RS driven by Porsche test driver Lars Kern set a 6:47.3 minute lap time around the Nürburgring Nordschleife, averaging a speed of. This made it the fastest production car lap time recorded on the track at the time.
In 2018, Warren Luff at the wheel of the GT2 RS set the fastest production lap record at The Bend Motorsport Park with a lap time of 3:24.079 minutes around the 7.77 km GT layout.
On 25 October 2018, a 6:40.33 minute lap time around the Nürburgring Nordschleife was set by Porsche test driver Lars Kern in a 911 GT2 RS MR prepared by Porsche-owned Manthey Racing, surpassing the previous record holder—an unmodified Lamborghini Aventador SVJ—that had deprived the GT2 RS of its record in July 2018.
In 2019 Porsche set further production lap records with the car at various North American circuits: 1:24.88 minutes at Road Atlanta, 2:15.17 minutes at Road America and 1:22.36 minutes at Canadian Tire Motorsport Park.
