Porsche 911 GT3 R made its world debut at the autosport international show 2010. Porsche 911 GT3 R succeeds the 911 GT3 Cup S and is developed for racing series based on the international FIA GT3 regulations. The starting point in developing the 911 GT3 R was the latest 3.8-litre Porsche 911 GT3 Cup, which will compete in the 2010 Porsche Mobil 1 Supercup supporting selected Formula One races. However, the GT3 R - which weighs just 1,200 kg (2,646 lb) - has a larger 4.0-litre six-cylinder ‘boxer’ engine delivering 480 bhp and other technical developments designed to improve the performance of the car further still.
