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
