The XJR-12 was one of the most successful race cars in the early 90’s. Chassis 190 was able to make some solid results, one to be noticed would be in 1990 where the car would qualify 7th and finish 1st in the Daytona 24 Hours while being driven by Andy Wallace, Jan Lammers and Davy Jones and was an incredible result for Jaguar. The XJR-12 won Le Mans in 1990 and would win Daytona to take the double crown. The XJR-12D was close to getting a second Daytona 24 Hour victory finishing first in class not far behind the winning R91CP in 1992.

After entering a few events in 1992 the car would eventually return to the Daytona 24 Hours. After qualifying 6th and leading the pack for part of the race, Chassis 190 did not finish due to engine problems. For the second XJR-12 bad luck struck near the start of the race resulting in a retirement. Finally the 3rd XJR-12D (D meaning Development) entered was fairly different to the other 2, this one having a 2 tier wing being copied from the XJR-16 and the rims uncovered. After the shocking result of even the 3rd car not being able to start, the result would mark the end of the XJR-12D.

The ‘90s was a good decade in IMSA where there was a lot of competition from Japanese brands including Toyota, Nissan and even Mazda. Jaguar and TWR being the only British entrant at the time had the upper hand on the competition. The XJR-12D was a direct development of the Le Mans winning XJR-9 and proved the smallest changes could often make a difference.

The XJR-12 first ran a 6 litre naturally aspirated V12 twinned to a TWR 5 speed manual gearbox and overall produced 730hp at 7000rpm. The XJR-12 was quick, in 1990 it was able to hit the speed trap on the Mulsanne at 219mph. It ran a lightweight Carbon Fibre monocoque and overall the car weighed 900kg.
