The XK combines Jaguar's new modern design style with traditional luxury car touches like genuine wood and supple leather.

Available as a coupe and convertible, the XK offers a 300-horsepower V8 engine. The six-speed automatic transmission with console mounted shifter and steering-wheel-mounted paddle shifters channels all that power to the rear wheels. Standard equipment includes navigation, keyless entry and keyless start, a seven-inch video display, Bluetooth, rear park assist, and electronic parking brake.

2008 Jaguar XK

Changes to the Jaguar XK for 2008 are few, but a new Portfolio edition will be offered - and stocked fully with new trim. As a Portfolio-ed model, the XKR stays with its supercharged, 4.2-liter V-8, which pushes it to 60 mph in 4.9 seconds in coupe form (5.0 seconds for the convertible).

The chief distinguishing features of the XKR Portfolio are mainly cosmetic. The front bumper is slightly reshaped, the hood gets louvers and the grille and side vents get metallic trim. Black is the color of choice, and 20-inch Cremona five-spoke wheels are fitted.

Behind the big wheels are new brakes - with front rotors almost two inches wider, pinched down upon with six-piston calipers, and four-piston calipers on the rear discs.

The XKR's sumptuous cabin gets aluminum trim or optionally, American walnut. The gear lever is trimmed in leather and metal, and the leather-trimmed cabin gets contrasting stitching. The audio system's speakers are supplied by Bowers & Wilkins.

Jaguar will take orders for the XKR Portfolio beginning this month. Only 255 copies will be offered for the U.S. market.

Other changes to all XKs for the 2008 model year include new convertible roof colors, available run-flat tires, a new spoiler-mounted radio antenna, and standard polished steel pedals for the XKR. The base XK sticks with the non-supercharged 4.2-liter V-8.
