Jaguar has revealed the all-new XK.

When it is launched in early 2006, this first of the next generation of Jaguars will become the sporting flagship of the brand – and is being hailed as the most technically and technologically advanced Jaguar ever.

The new car succeeds the Jaguar XK range introduced in 1996. All-aluminium construction forms a lightweight, stiff and strong car.

Technological highlights include intuitive controls and ‘driver-focussed’ technologies – such as keyless entry, push button start and active lighting – enhance driver enjoyment

The car launched with latest generation naturally aspirated 4.2-litre Jaguar AJ-V8 engine, developing 300bhp controlled via a new Jaguar sequential shift six-speed automatic transmission system incorporates steering wheel-mounted paddles for manual gear changes.

This gives the XK a 0-60mph from standstill time of 5.9 seconds and completes quarter mile sprint in 14.4 seconds – less than half a second off the pace of the previous 400bhp supercharged model. Top speed is an electronically limited 155mph.

A convertible model will also be available with details announced later this year.

The all-new XK’s bodyshell is 31% stiffer than the previous XK’s and offers a 10% improvement in power to weight ratio. The all-new XK is up to 90% stiffer and 180kg lighter than key rivals, with a kerb weight of just 1595kg.

Jaguar's chief engineer Mike Cross, in charge of the all-new XK’s vehicle dynamics: "What the team has looked to engineer is a sports car with true all-round ability. That means it must be fast, outstandingly agile, and truly exciting to drive. It has to go quickly, stop quickly, and do everything in between in the way a Jaguar should. Yet it’s also a rational choice – the all-new XK will deliver a balance of superb driving dynamics and comfort that is the epitome of sophisticated sporting luxury."
