The XJR’s 400-hp, supercharged, 4.2-liter V8 and sport-tuned suspension are the key differences between it and the non-supercharged XJ8. Sitting still, there is not much to distinguish the XJR from other models in the XJ line besides bigger wheels and the body-color area surrounding the front mesh grille. Such tasteful understatement avoids tacky exterior add-ons like scoops and spoilers that sometimes plague high-performance versions of other luxury sedans.
Because of its sporting intentions, the Jaguar XJR comes only in the regular wheelbase, the same as in the Jaguar XJ8. For those who want the ultimate in performance but prefer a larger rear seating area and more-luxurious appointments, the Super V8 offers the 400-hp, supercharged engine of the Jaguar XJR, with the extended-wheelbase body style also found on the XJ8L and Vanden Plas models.
Upgraded wheels and tires plus a sport-tuned version of Jaguar's automatic-adjusting Enhanced Computer Active Technology Suspension combine to deliver precise handling with a relatively smooth ride. Upgraded brakes feature emergency brake assist, while stability control and traction control help maintain traction when the roads get slick or driving gets treacherous. Front side and head-curtain airbags are standard.
Inside the handsome wood- and leather-trimmed cabin, power sport seats with perforated leather inserts are specially designed to hold the driver and front passenger firmly in place during aggressive cornering maneuvers. All seats, front and rear, plus the steering wheel are heated.

The Jaguar XJR also has radar-based adaptive cruise control that maintains both a set speed, and distance from traffic ahead; navigation; and a high-powered audio system. The few options include satellite radio and a rear-seat DVD entertainment system.
The Jaguar XJR, along with the rest of the XJ line, was completely redesigned in 2004 with an extensive use of aluminum in its construction, which cuts weight and helps structural rigidity.
