caption_attribution_description: The Porsche 911 GT1 is a car designed for competition in the GT1 class of sportscar racing, which also required a street legal version for homologation purposes, built from 1996-99. In spite of its 911 moniker, the car actually had very little in common with the 911 of the time, however its frontal chassis was shared with the then (993) 911, while the rear of the car was derived from the Porsche 962. The engine was longitudinally-mounted in a rear mid-engine, rear-wheel-drive layout, compared to the rear-engine, rear-wheel-drive layout of a conventional 911. The 911 GT1 won its class at LeMans in 1996 In 1997, now the GT1 Evo, the front end of the car was revised including new bodywork which featured headlamps similar to the new 911 of that year. Reliability problems failed to give the GT1 success this year. A new body in 1998, the 911 GT1-98, despite being slower than the Toyota or the Mercedes, fulfilled Porsche's slim hopes, taking both first and second place overall at LeMans. The GT1 class was cancelled in 1999 Engine; 592hp 3164cc twin turbocharged flat six Photographed at the Peterson Museum
context_page_description: The Porsche 911 GT1 is a car designed and developed by German automobile manufacturer Porsche AG to compete in the GT1 class of sports car racing, which also required a street legal version for homologation purposes. The limited-production street-legal version developed as a result was named the 911 GT1 Straßenversion.
context_section_description: In spite of its 911 moniker, the car actually had very little in common with the 911 of the time, only sharing the front and rear headlamps with the production sports car. However, its frontal chassis was shared with the then (993) 911, while the rear of the chassis was derived from the 962 along with its water-cooled, twin-turbocharged and intercooled, 4 valves per cylinder 3,164 cc (3.2 L) flat-six engine fuel fed by Bosch Motronic 5.2 fuel injection, which was longitudinally-mounted in a rear mid-engine, rear-wheel-drive layout, compared to the rear-engine, rear-wheel-drive layout of a conventional 911. The engine generated a power output of about 600 PS (441 kW; 592 hp). In comparison, the 993 generation 911 GT2, which was otherwise the company's highest-performance vehicle at the time, used an air-cooled engine with only two valves per cylinder.
  The 911 GT1 made its debut in the BPR Global GT Series (the FIA championship's predecessor) at the Brands Hatch 4 hours, where Hans-Joachim Stuck and Thierry Boutsen won comfortably, although they were racing as an invited entry and were thus ineligible for points. They followed up by winning at Spa and Ralf Kelleners and Emmanuel Collard triumphed for the factory team at Zhuhai.
  The 1996 911 GT1 clocked at a top speed of exactly 330 km/h (205 mph) on the legendary Mulsanne Straight in the practice sessions of the 1996 Le Mans 24 Hours Race.
