Updated last year with a new Super V-8 Portfolio edition, the XJ full-size sedan rolls into 2007 with minor tweaks and updates, including iPod and MP3 capability and new wheel designs for all models. The standard XJ8 comes powered by a 300-horsepower, 4.2-liter V-8 engine working through a ZF six-speed automatic. Major features include an adaptive, self-leveling suspension, 18-inch wheels, premium leather interior with accent piping, new-for-2007 elm trim and a 140-watt AM/FM sound system with single in-dash CD player and Bluetooth wireless technology. The long-wheelbase L edition adds a power rear sunshade and much roomier back seats. The Vanden Plas model kicks it up another notch with 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 6-disc trunk-mounted CD changer. DVD-based navigation is also standard on Vanden Plas XJs. For enthusiast drivers, the high-performance R model returns, with a supercharged V-8 and 400 horsepower. Nineteen-inch wheels are standard (with 20-inch wheels available optionally) as well as Adaptive Cruise Control and R-specific interior and exterior trim. The ultra-luxury Super V-8 comes in at the top of the food chain, bundling all of the luxurious interior amenities of the Vanden Plas with the supercharged drivetrain of the XJR. Additional features include manual side window sun blinds and multimedia entertainment system with twin 6.5-inch monitors in the back of the front seat head restraints and DVD player.
