Everyone knows Jaguars are comfortable and convey elegance to those inside them, but few probably think of these luxury chariots as being in the same league with the BMW M5 or Mercedes-Benz E55. Think again. Think 2004 Jaguar XJR. This 4-door sedan combines a 390-horsepower V-8 with a six-speed automatic transmission to match performance numbers with those competitors, and at less cost. With Jaguars, the R designation stands for "roars". Prices: US: base $74,330.
Heritage
Jaguar is very careful with design changes. So much so, in fact, that the 2004 Jaguar XJR still resembles the remarkable 1968 Jaguar XJ. So good was that car that almost all competing Jaguar salon models were dropped. And, even the engine size of today's model, if not the configuration, is the same, at 4.2 liters. But this 2004 V-8 reminds us of Jaguar's legendary racing cars, pumping out 390 horsepower under a supercharger. It can leave even the V-12 XJ models introduced in 1972 in its dust easily. The 1972 XJ V-12 traveled 0 to 60 in 7.4 seconds. The 1975 XJ-S with its V-12 did it in 6.9 seconds. The 2004 Jaguar XJR romps the same speeds in 5.1 seconds! The V-12 died after 1997, succeeded by smaller engines with more power and better fuel efficiency. This 2004 model happily combines performance, handling and comfort. And with the 2004 Jaguar XJR's $74,330 base price, it is less expensive than any competing luxury sports sedan.Coachwork

On the Road
The most unusual feature of the 2004 Jaguar XJR is adaptive cruise control, a system that maintains the vehicle's highway speed and spacing, even in heavy traffic. Jaguar uses a radar unit on the driver's side under the front bumper to measure distance and then adjusts the car's throttle and brakes as needed by traffic conditions. The system never faltered, matching the flow of traffic on a busy interstate highway for more than an hour. Under the bonnet, which opens from the front now, is a 4.2-liter V-8 with a supercharger, pumping out 390 horsepower. Acceleration at any speed is smooth and rocket-like. Big Brembo brakes mean you stop in a hurry, too. There's traction control and stability control at all times. An adaptive air suspension works with huge tires to corner the 2004 Jaguar XJR at insane speeds. The six-speed automatic transmission has a tall final gear, helping to return 24 miles per gallon at highway speed. Comfort is always a key with Jaguar, and the suspension never pounded those inside, yet was ready for that right-hand sweeper at any time. Operations such as headlights and windshield wipers are automated. Ultrasonic emitters front and rear assist in parking with audible "beeps" as the XJR approaches an object.Summary
