 Jaguar were approached by racing team owner Tom Walkinshaw and encouraged to enter the Jaguar XJS into the 1981 European Touring Car Championship; they succeeded in winning the competition in 1984. Jaguar had started to provide factory support to racing team Group 44 Racing, who were using the Jaguar-engined XJR-5 in the IMSA GT Championship, supplying V12 engines from 1983 onwards and supporting a Le Mans entry in 1984. Tom Walkinshaw and Jaguar agreed to entering the FIA Group C World Sportscar Championship and developed the XJR-6, which was powered by the Jaguar V12 engine; the car was launched during the 1985 season.
