Germans have given the 5.0-litre V8 Jaguar F-Type 693bhp and stripes

A German tuning company has given an old British car a lot of power and minimal wheelarch clearance. Welcome to the Arden AJ 23 RS: an even more hardcore version of a fairly hardcore car.

That car being the old Jaguar F-Type. Are we allowed to talk about the old Jaguar F-Type? Feels a touch seditious to look upon the Jag’s delightful lines when all talk is focused – rightly so – on the future and the incredible Type 00.

But that Type 00 exists because despite everyone loving the old F-Type, not enough people bought one. So here we are. This one’s naturally packing a lot more power from its supercharged 5.0-litre V8 engine courtesy of some new software.

Arden has also modified the supercharger drive for more boost pressure, and bolted on a special 'valved' exhaust system. Considering the regular F-Type V8 sounds incredibly naughty, one can only imagine what noise this summons from the deep.

And there is much deep. Power jumps up to 693bhp and 644lb ft of torque, sent to either the back wheels or all of them (depending on spec), via an eight-speed auto.

Arden’s dropped the F-Type by 30mm by deploying lowered KW coil springs – it mentions ‘stance’ more than handling, so sure, why not – and has slotted in 21in one-piece lightweight alloys. Behind that, you can option up full-on carbon ceramics, or better steel units that offer a considerable upgrade on the F's regular stoppers.

It’s also slotted on a new front apron, new side skirts, a ‘powerful’ rear bumper, and stripes. Stripes make all the difference. This is the finished car, but you can cherry pick whatever upgrades you desire on this still-desirable old British car.
