The standard XJ8 comes powered by a 300-horsepower, 4.2-liter V-8 engine working through a smooth-shifting ZF six-speed automatic. Performance for this version is just quick enough for a luxury car, but with fuel economy of 16/25 mpg, a good figure in this class. A long-wheelbase L edition gets more legroom for the backseat without a big penalty in weight and none in fuel economy. The Vanden Plas takes the long-wheelbase edition and adds as standard front park control, folding rear picnic trays, lambswool rugs, and a 320-watt Alpine premium sound system with AM/FM radio, single in-dash CD player, and six-disc trunk-mounted CD changer, as well as DVD-based navigation.

Two supercharged cars, with more breathtaking performance, are offered. The XKR’s 4.2-liter V-8 makes 400 horsepower, and like the standard car, it’s coupled to a smooth-shifting six-speed automatic. Nineteen-inch wheels are standard (with 20-inch wheels available optionally) as well as Adaptive Cruise Control and R-specific interior and exterior trim. Atop the range is the Super V8, which marries the Vanden Plas trim with the supercharged V-8.
