The McLaren F1 GTR is the racing variant of the McLaren F1 sports car first produced in 1995 for grand touring style racing, such as the BPR Global GT Series, FIA GT Championship, JGTC, and British GT Championship. It was powered by the naturally aspirated BMW S70/2 V12 engine. It is most famous for its overall victory at the 1995 24 Hours of Le Mans where it won against faster purpose-built prototypes in very wet conditions. The F1 GTR raced internationally until 2005 when the final race chassis was retired. From Wikipedia
