Jaguar plotted the XKR as a stealthy speeder, which explains the relatively minor cosmetic changes that distinguish it from the XK8. Those distinguishing details: The XKR grille is wire mesh and the crests of its fenders bear louvers. (The twin louvers are located in an aerodynamic low-pressure zone, creating an extractor effect that helps draw air through the radiator pack at an increased rate.) A brief spoiler crests atop the trunk's aft edge, XKR lettering adorns the trunk lid and doorsills, and the traditional Jaguar badges have red backgrounds.

Nothing detracts from the gorgeous shape, however. As time passes, we seem to grow even more fond of the XK silhouette, with its leonine lines and subtle body curvature. It's rolling art - a supermodel translated into sheet metal. There's a distinctly feminine air about the XKR, especially inside, where voluptuous curves dominate the outward view, unlike the Teutonic creases evident from behind the wheel of a Mercedes SL.

While the XKR grabs the headlines, the XK8 has been upgraded for 2000: The anti-lock braking system has been revised to the Electronic Stability Braking System and the front disc brake rotors have been enlarged. Also adding to safety are front seat belt pretensioners that are now electrically actuated. The standard audio system is upgraded to six speakers and a new 320-watt Alpine Premium Sound system is available as an option. New standard equipment includes new alloy wheels, traction control, rain-sensing windshield wipers, a trunk cargo net, de-powered front air bags, and, for the coupe, child seat tether anchors.
