Why it matters
The XJR-15 was a road-going car derived directly from the XJR-9 and XJR-12 Group C racers, built by Jaguar Sport and TWR. A one-make series, the Jaguar Sport International Challenge, was run for it in 1991 as a Formula 1 support race.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionXJR-15s made, of which 27 left in roadgoing specification | 531,2 | Factory production | Disputed |
Sources differ: RM Sotheby's says 53 XJR-15s made (27 roadgoing), Ultimatecarpage lists 50 numbers built.
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
After the 1988 Le Mans win, Jaguar Sport and TWR chose to develop a racing car for the road. The car was first meant to be called XJR-9R. Its carbon-fibre monocoque and running gear were virtually the same as the XJR-9, and a six-litre V12 based on a production engine gave about 450 bhp.
The first body followed the XJR-9 but was impractical for the road, so Peter Stevens was hired to draw a body suited to both road and competition, with more glass, proper doors and a small rear wing.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
The XJR-15 is a Group C-derived car with a Peter Stevens body of carbon fibre and Kevlar composite, a composite monocoque with the 60 degree V12 acting as a stressed rear member, and ground-effect venturi channels under the body. It sits on OZ forged alloy wheels, 9.5 x 17 in at the front and 13 x 17 in at the rear, with Pirelli P Zero 250/30 R17 and 320/35 R17 tyres. Road cars were fitted with bumpers and indicators and a raised ride height. A press report of the launch says the cars would be built in Kidlington, with 30 built in the first winter and no more than 50 in total.
