2004 Jaguar XJ8 also is available in a long-wheelbase version. the XJ8 Vanden Plas. mated to the same power-train. If you need a quicker kitty. you'll want to opt for the XJR. which takes a sporting approach to the standard XJ8. This includes replacing the standard V-8 with a supercharged version of the 4. 2-liter V-8. At 390 horsepower. this car reaches 60 miles per hour 1. 3 seconds sooner than the standard car. MPG City: 17 - 18 ; Highway: 24 - 28Not that you'd really notice. Both the XJ8 and XJR feel plenty quick on their feet. The supercharger's whine and slightly quicker response is the only difference that most people will notice. That means most will find the XJR's $74. 95 base price harder to swallow than the XJ8's $59. 95 base price. If $59. 95 sounds more like a nice yearly salary than the base price of a car. realize that the 2004 XJ8 starts at $13. 25 less than the Mercedes Benz S420. one of Jaguar's key competitors. Certainly from a performance standpoint. there's little to complain about and much to praise. The 2004 Jaguar XJ8 and XJR continue to deliver the superb. cat-like reflexes and luxurious ride without a feeling of floating.
