The Jaguar XJR sportscars were a series of race cars used by Jaguar-backed teams in both the World Sportscar Championship (WSC) Group C and the IMSA Camel GTP series between 1984 and 1993.

History

1985 season]].

Jaguar would continue to use two different types of chassis for IMSA and the WSC until 1988 when Jaguar chose to have TWR take over their team for both championships, and building an identical car for both series, known as the XJR-9.

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. However, the FIA announced rule changes to come into effect for the WSC that would require all teams to change to 3.5L naturally aspirated engines. TWR decided that continuing to develop their V6 in the WSC was useless, so the new XJR-12 for the WSC in 1990 was better suited to carry the old but reliable V12. 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.

After having won multiple championships in the WSC, and instability due to multiple rule changes, Jaguar decided to drop out following the 1991 season and concentrate on IMSA. However, after attempting the first few races of the 1993 season, Jaguar decided to end the project altogether, marking the end of the XJR sportscars. Jaguar and TWR attempted to continue racing on with a cheaper and smaller scale project, a racing version of the XJ220 for the GT classes, but it was short-lived.

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. Several XJR-15s were also built into racing cars for a special one-make series meant as a support race for Formula One.
