Turning to XF

14 May 2008 - 11:00

Seems some people aren't patient enough to wait until next year for the hotted-up Jaguar XF-R to arrive. The Euro-tuners at Arden have had their own shot at beefing up the big saloon, and the result - the AJ 21 - is, well, unmissable.

The XF's 4.2-litre V8 has been bored out to 4.5 litres, raising power to just over 500bhp. Naturally it sits lower on harder suspension, while 21-inch alloys promise to do no favours to your lower back.

You might have noticed the, erm, distinctive bodykit too, with its big front apron and LED running lights at the front, and weird brake cooling ducts ahead of the rear wheels.

An improvement on the subtle, understated stock XF? We'll let you decide.
