Jaguar XJR sportscars

Starting in 1983, the project was started by an American team Group 44 Racing, headed up by owner-driver Bob Tullius, who had the backing of Jaguar to build the Fabcar designed racer known as XJR-5 in their Herndon, Virginia, US, shop and to campaign it in the IMSA Camel GTP championship.

After becoming established in IMSA, Jaguar turned to Tom Walkinshaw Racing (TWR) to develop another car known as XJR-6 for the World Sportscar Championship,[1] using the same Jaguar V12 engine, and debuting halfway into the 1985 season.

After having used the V12 in a variety of sizes, TWR decided to try a new turbocharged 3.5L V6 for the XJR-10 (for IMSA) and the XJR-11 (for the WSC) in the 1989 season.

The XJR-12 was short-lived, as in 1991, Jaguar decided to debut their new 3.5L naturally aspirated V8 engine by Cosworth for the XJR-14.

One unique XJR model was the 1990 XJR-15, which was a limited-edition road-legal supercar built by TWR from the design of the XJR-9 and featuring Jaguar's V12.
