The Jaguar XK (XK, XK8 and XKR) is two door grand touring two-seater manufactured and marketed by Jaguar Cars from 1996-2014 in coupé and convertible bodystyles, across two generations. The XK was introduced at the Geneva Motor Show in March of 1996 and was last manufactured in July of 2014. The first generation was marketed as the XK8, replacing the XJS and was Jaguar's first 8-cylinder model since the Daimler 250, introducing the Jaguar AJ-V8 engine. The second generation XK, noted for its aluminium monocoque bodyshell, was launched in 2006 for model year 2007. Both generations were marketed in performance variants, as the XKR.
The redesigned XK debuted in 2005 at the Frankfurt Motor Show in Germany, styled by Jaguar's chief designer Ian Callum. The X150's grille was also inspired from the famous 1961 Jaguar E-Type.The standard XK model has an unlimited top speed of 158 mph whilst the XKR an unlimited top speed of 174 mph. An even faster variant, the XKR-S model was introduced at the Geneva Motor Show in 2012. The XKR-S gained an additional 40-horsepower over the XKR bringing the 0-60 mph time down to only 4.4 seconds and the top speed up to 300 km/h (186 mph) - making it the fastest Jaguar yet after the Jaguar XJ220. A convertible version of the XKR-S was released in 2012. Production of the XK ended in July 2014 without a replacement model until the subsequent F-Type.
