Why it matters
A four-wheel-drive, twin-turbo XJS built as a test bed for the XJ41/42 sports car, which was cancelled in 1990, leaving the car redundant. Its drive system anticipated the X-Type, Jaguar's first production four-wheel-drive car.
How rare is it?
Six separate kinds of rarity – never combined into one number.
Each kind of rarity is rated separately and never combined.
02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productiondevelopment XJSs built with four-wheel drive | 31,2 | Factory production | Factory reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
The XJ41 gained weight during development, so the AJ6 engine was turbocharged, to at least 330 bhp, and four-wheel drive was adopted to handle the power. It is thought three XJS mules were built with four-wheel drive, in cooperation with FF Developments: one V12, one non-turbo six and this car with twin Garrett turbochargers and an alleged 400 bhp.
The base car was built in April 1987, originally as left-hand drive for Germany, with a manual gearbox, and was allocated to Engineering. The conversion took more than two years to develop. It reached about 155 mph (250 km/h) and 0-60 mph in a little over five seconds. Registration is G974 BRW and chassis number SAJJNAEC8CL141199.
