The Jaguar XK series (XK, XK8 and XKR) is a series of grand tourer cars produced by British car maker Jaguar Cars since 1996. The series was introduced at the Geneva Motor Show on 5 March 1996. The first generation of the series, the XK8, replaced the XJS, and was available as a coupé and convertible. The XK8 was the first 8-cylinder vehicle produced by Jaguar since the Daimler 250, introducing the Jaguar AJ-V8 engine.
The second generation XK was launched in 2006 (as a model year 2007). The new XK introduced an aluminium monocoque bodyshell, and is available both as a two-door coupé and two-door cabriolet/convertible, with just the engine and associated mechanicals being carried forward.
