The 1997 XK8 (project code X100) was available in coupé or convertible body styles and with either a supercharged 370hp (276kW) or naturally aspirated 290hp (216kW) engine. The supercharged variant is known as the XKR. The first-generation XK series shares its platform with the Aston Martin DB7. Both cars are derived from the Jaguar XJS, though the platform has been extensively changed, with co-efficient drags of 0.35 and 0.36 for the XK8 coupe and XK8 convertible respectively.
Power and performance
Both the XK8 and XKR are electronically limited to a maximum of 155mph (250km/h), lower than the top speed of its predecessor. The XK8 heralded a change in direction for the company, resulting in the S-Type and X-Type.
Both the XK8 and XKR come standard with 18-inch alloy wheels, and 19 and 20-inch wheels are available for additional cost. A navigation system and self-leveling xenon headlamps come standard with the XKR and as options for the XK8. Jaguar's Adaptive Cruise Control is an optional feature available on both models. Both come with all-leather interior, burl walnut trim, and side airbags. Jeremy Clarkson, during a Top Gear (a UK motoring magazine/TV show) test-drive, likened the interior of the original XK8 to sitting inside Blenheim Palace. In 2005 the grille design of the XKR was refreshed.
