A series of subtle upgrades has been applied to the 2004 Jaguar XK.

The XK has been given a more contemporary feel with the addition of a revised nose and rear section, complemented by new side sills, wheels and trim. The XKR also gets a new mesh grille, supplemented by a lower 'mouth profile' in the front bumper.

There are also larger exhaust tail-pipe finishers for XK8 models and new quad tailpipe finishers for the XKR. Three new multi-spoke wheel styles are introduced -- 18-inch Aris, 19-inch Atlas and 20-inch BBS Sepang. All XK8 models now have a rear spoiler as standard, while the XKR has a new, larger rear spoiler.

All UK Jaguar XK buyers will have the option of increasing the specification of their car by choosing new Premium and Technology packs. These optional packs combine extras such as reverse park control, sports seats, larger wheels and revised interior trim.

A new automatic speed limiter is added to the wide range of electronic systems already standard across the XK range. From its launch in 1996, the XK8 rapidly became the fastest-selling sports car in Jaguar's history.

A programme of enhanced electronics and other equipment options that focused on safety, comfort and ease at the wheel was implemented in 2001. All XK models were fitted with the Jaguar A.R.T.S. Adaptive Restraint Technology System and Adaptive Cruise Control was an added optional extra.

In 2003 a major update to XK powertrains saw the introduction of larger, more powerful 4.2-litre V8 engines (in 300 horsepower normally aspirated form and a 400 horsepower supercharged version), a six-speed automatic transmission and further key features including Emergency Brake Assist (which increases brake force in an emergency) and Dynamic Stability Control.
