The Porsche 911 GT2 is a high-performance sports car built by the German automobile manufacturer Porsche from 1993 to 2009, and then 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 upgrades, larger brakes, and stiffer suspension calibration. The GT2 is significantly lighter than the Turbo due to its use of rear-wheel-drive instead of all-wheel-drive system and the reduction or removal of interior components. As a result, the GT2 (now GT2 RS) is the most expensive and fastest model among the 911 lineup.
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 515 kW (700 PS; 691 hp) at 7,000 rpm and 750 lbft 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 0-97 km/h (0-60 mph) in 2.7 seconds, and has a top speed of 340 km/h (211 mph).
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 1,470 kg (3,241 lb).
A Weissach package option is available, which reduces weight by 30 kg (66 lb), 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. The car was available in the United States from early 2018.
A production run of 1,000 units was planned.
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 184.11 km/h (114.40 mph). 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 (without the Weissach package) 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 dethroned the GT2 RS of its record during 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.
From the "In the Wrapper" Collection, this as new example has delivery miles only and has been kept in climate controlled storage since new. The car is fully up to date on all service-the only miles logged having been to the dealer and back. Finished in the desirable Chalk color combination with the rare Weissach package, this is the GT2RS to buy if you are looking for the the finest example.
