Power for the normally-aspirated XJ8, XJ8L and Vanden Plas models comes from a refined 4.2-liter V8 of 300 horsepower, while the XJR and Super V8 receive an additional 100 horsepower...
in the form of a supercharged V8 engine. The XJ rides on a remarkably capable chassis, highlighted by an adaptive rear air suspension that keeps it planted in a way the old model never could. The system is solid, secure and serene, with great higher-speed control and an appropriately smooth ride that's completely in character with this car's image.
All-new 18-inch alloy wheels look smart and contribute to enhanced handling capabilities, and the XJR and Super V8 get even more aggressive 19-inch wheels and tires that further upgrade ultimate handling but also somewhat diminish the luxurious, soft ride of the base XJ.
