2001 Jaguar XKR-R Concept
The ultimate expression of Jaguar’s top-of-the-line XKR-R is motivated by a supercharged V-8 engine boosted to over 400 horsepower. Not a single component escaped Jaguar’s Special Vehicle Operations (SVO) team’s attention in the metamorphosis from stock XKR to the unique XKR-R, from the shape of the front bumper to the quad-outlet exhaust.
SVO began strengthening the rear by installing an eight-point roll-bar. The rear suspension is greatly revised from the stock XKR, and features the entire rear floor area from the S-TYPE sedan, along with the rear axle from an S-TYPE. The new axle provides for a better range of adjustment and tuning.
The XKR-R rides lower than a stock XK8 by 30 millimeters, and the purposeful look of the car is further accentuated by the fitting of Jaguar’s own 20-inch BBS-sourced R-Performance wheels. The wheels are filled with Jaguar’s Brembo-sourced R-Performance brake calipers and cross-drilled rotors. With the addition of specially produced front and rear bumpers, sculptured rocker panels and trunk lid spoiler, the car looks more purposeful and aggressive.
Inside, the XKR-R is a showcase for planned R-Performance dealer-installed options and one-off components. In addition to the rollbar, SVO installed Recaro racing seats and four-point seatbelts.
Behind the engine, SVO replaced the stock five-speed automatic transmission with a customized Tremec T-56 six-speed manual unit, similar to that found in the Dodge Viper and Chevrolet Corvette. The T56 is a stout unit, and paired with an AP Racing twin-plate clutch, is a suitable partner for the XKR-R’s power and torque.
