The XK8 shared its platform with the Aston Martin DB7 which was itself based on the stillborn XJ41/42 project built on a modified XJ-S chassis conceived in the mid-1980s.

Visual differences from the XK8 included a rear spoiler, mesh front grille and hood louvres on the bonnet for improved airflow to the engine.

The models were revised again in spring 2004 and notable changes included new wheel designs, bigger front and rear spoilers and a redesigned grille.

The second generation of the XK debuted in 2005 at the Frankfurt Motor Show in Germany, styled by Jaguar's chief designer Ian Callum.

The XK is an evolution of the Advanced Lightweight Coupé (ALC) introduced at the 2005 North American International Auto Show.

The XK features a bonded and riveted aluminium chassis shared with the XJ and body panels, both a first for a Jaguar grand tourer.

The interior also received some changes, in particular the introduction of the XF style rotary gear selector mated to the new ZF automatic transmission.

The XK received a second and more minor facelift in 2011 with new front bumper and light design,[11] which was presented at the New York Auto Show.
