The Jaguar XK is the second and final generation of the Jaguar XK 2+2 grand tourer manufactured and marketed by British automobile manufacturer Jaguar Cars under the X150 internal designation. The three-door fastback coupé debuted at the 2005 Frankfurt Motor Show with the 4.2-liter V8 engine of its predecessor, and the two-door convertible debuted in 2006 at the North American International Auto Show.
The X150 is noted for its all-aluminium construction and its styling by Ian Callum, with details evoking prominent earlier Jaguar models, e.g., the Sayer nose recalling the XP/11 sports racing prototype of 1953 and adopted for the D-type – and the grill located badge recalling the E-type.
A facelifted XK was launched in 2009 with a new 5.0-liter V8. The production of the XK ended in July 2014 without a replacement model, with a total production of just under 54,000 units.
