2008 Jaguar XJR

A Quicker Cat

A 400-hp V8 engine and other performance upgrades give the top Jaguar XJR an aggressive demeanor to go along with its upscale accommodations.

Jaguar is trying to get nine lives out of its XJ series of large luxury sedans, stretching it to what it considers to be five different models, led by the high-performance version, the Jaguar XJR. The sporty XJR continues to stand out for its deft balance of comfort and high performance.

The XJR’s supercharged 400-hp 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-colored 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 with a standard-length 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 engine of the Jaguar XJR with the extended-wheelbase body 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 smooth ride. Upgraded brakes feature emergency brake assist, while stability and traction control help maintain grip when the roads get slick. Front-side and head-curtain airbags are standard.

The Jaguar XJR has radar-based adaptive cruise control that maintains both a set speed and distance from traffic ahead, a navigation system, 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. Aluminum was used extensively in their construction to cut weight and help structural rigidity.
