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 a limited top speed of 158 mph whilst the XKR a limited 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.
