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 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 N⋅m (553 lb⋅ft) 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).
