The Porsche WSC-95 (sometimes referred to as the TWR WSC-95) was a Le Mans Prototype originally built by Tom Walkinshaw Racing. It was modified by Porsche from the original Group C Jaguar XJR-14 from which it derived, and run by Joest Racing. The WSC-95 saw very little race action even though it won the 24 Hours of Le Mans in both 1996 and 1997 without being acknowledged as a factory supported project. Later upgraded to the Porsche LMP1-98 before being retired. Only two cars were ever built.
