Porsche 911
The Porsche 911 GT1 is a car that was developed in 1996 for the GT1 class in the 24 Hours of Le Mans. In order to qualify for GT racing, 25 road-going models were built to achieve type homologation. The car developed around ( for the street version) and accelerated from 0–60 mph in 3.3 seconds. The top speed was . Both the road and race cars carried the same twin turbocharged engine as used in the 962, and the race car was a match for the then dominant McLaren F1 GTRs. A redeveloped version of the 911 GT1 race car was later built, winning outright at the 1998 24 Hours of Le Mans. The car is not considered to be a real 911, as it is derived from the 962 with the 996 911's front section. It was the most powerful and fastest road-going Porsche until the introduction of the Carrera GT in 2004 and later the 918 Spyder in 2013.
