The XJR-15 is the lesser known sibling of the Jaguar XJ220. Only 27 were ever built. The XJ220 may not have received the same recognition and reverence as the Ferrari F40, the Porsche 959, and the McLaren F1, but for a time it held the record for the fastest road-going automobile, 217.1 mph. All of the XJ220's engineering and prowess is owed to the development of the XJR-15, which in turn owes everything to driver Tom Walkinshaw and his experience in touring and Le Mans racecars.
Unlike the twin-turbocharged XJ220, the XJR-15 features a big, naturally-aspirated V12 that turned out 450 horsepower and 420 lb-ft of torque when new. The engine has a dry sump oil system, a Cosworth forged crankshaft, connecting rods, aluminum pistons, and fuel delivery from a Zytec electronically controlled sequential fuel injection system. The engine is mated to a five-speed transaxle from Tom Walkinshaw Racing, while the suspension - fabricated wishbones and horizontal pushrod-spring dampers at the front and coil springs at the rear - is pulled straight from the XJR-9 racecar.
At the time, the car was capable of hitting 60 mph in under four seconds and topped out at 215 mph, just shy of the mark later set by the Jaguar XJ220. The XJR-15 was also the first road car to make extensive use of carbon fiber. In fact, at 2,315 lbs, the car's listed weight is less than that of a new ND Mazda Miata. The body was designed by future McLaren F1 engineer Peter Stevens.
While the McLaren and Porsche were more complete and well rounded machines, the XJR-15 was a bare bones, uncompromised track machine. The interior was barely more than a carbon tub fitted with a pair of one-piece seats.
The car in this listing is chassis number 21 and only has 1,400 miles on the odometer. Some minor modifications to the hinges allow the hood and engine cover to be quickly and easily opened. The car is listed for £450,000, or about $560,000. Not cheap, but what rare, early 1990s supercar is?
