The British firm’s new 500bhp super saloon made a number of high speed runs up the famous hill, with veteran test driver Mike Cross behind the wheel.
Jaguar officials are still cagey about confirming the XFR’s existence, describing the disguised saloon as a ‘sports prototype’. But sources close to the XFR project hinted that a production model could be expected in March 2009.
The Jaguar XFR will be powered by a new direct injection, supercharged 5.0-litre V8 with 500bhp on tap. Expect scorching performance as a result; the XFR capable of dismissing 0-60mph in around 4.5 seconds and pressing on to a limited top speed of 155mph. Gaydon’s also expected to offer an option to remove the limiter, so 180mph+ will be possible.
The R will have a lower ride height and stiffer springs than today’s sportiest XF, the SV8. But that model will remain on sale to satisfy drivers who want a more comfortable chassis. The XFR will be the hardcore model.
Cosmetic changes include more vents and grilles to aid cooling, more aggressive bumpers and 20-inch alloys. Although Jaguar has agreed supplies of a new eight-speed ZF auto ‘box, at launch the XFR will only be available with the familiar six-speeder.
