StarLight Garage presents today the Group C racing version of the Jaguar XJR-15 from 1991.
Enjoy this racing beauty.
The XJR-15 was based on the same central monocoque “tub” as the Tony Southgate-designed XJR-9, and the body, designed by Peter Stevens, was constructed of lightweight and advanced composite materials by TWR Special Vehicle Operations. It is constructed of lightweight composite materials including carbon fiber and Kevlar
Only 23 XJR-15 were constructed to racing specifications.
XJR-9 suspension was retained all round with fabrication wishbones and horizontally mounted pushrod spring damper units at the front coil springs at the rear. Four pot AP Racing calipers mounted to disc brakes are housed completely within the wheels to maximize width of venturi tunnels.
The Group C-specification engine, a 450 hp, six-liter all alloy, dry-sump V-12, included a Cosworth forged crankshaft, connecting rods and aluminum pistons, with fuel delivery via Zytec electronically controlled sequential fuel injection. The transmission was a TWR six-speed transaxle with straight-cut gears, matched to an AP triple-plate carbon clutch.
Walkinshaw’s work resulted in a car weighing just 2,315 pounds and endowed with awesome handling, excellent power-to-weight, race-proven reliability and a 215-mph top speed.
All this came at a price of nearly one million US dollars.
The XJR-15 is considered Jaguar’s ultimate supercar, and its athletic lines rank with those of the fabled C-Type, D-Type and XJ13 in aesthetic appeal. However, its shattering performances eclipses that of its distinguished forebears.
This particular car #4 with serial number #011, was owned and driven in the series races by Bob Wollek. Mr Wollek a well respected and accomplished driver whose record includes a 2000 Le Mans win.
After the Spa race, the car was retired from professional competition.
