Following on from its brilliant take on the XKR, German tuning-house Arden has taken Jaguar’s latest XF saloon and created a machine even more impressive than its past works. Dubbed the Arden AJ21, the modified XF features a stronger engine, extensive aerodynamic modifications and a revised interior.

The new AJ21 receives a completely new front-end design with an enlarged radiator grill finished in stainless steel mesh as well as oversized air vents for cooling of the engine and braking system. The aerodynamic lift at the front axle is reduced with help of the lower lines of the new front spoiler, improving road-handling at higher speeds. Other features include integrated LED daytime running lights and new side sills with functional air inlets for improved cooling of the rear brakes. Up back is an aggressive diffuser melded into the rear bumper as well as a discrete decklid spoiler.

Arden offers performance modifications for all four engines offered by Jaguar in its XF saloon, from the 2.7L V6 diesel up to the supercharged 4.2L V8. The top of the line kit is based on the same supercharged 4.5L V8 from Arden’s previous AJ20 XKR. The engine uses a specially made crankshaft, along with new con rods and pistons to help achieve a 300cc increase in displacement over the standard motor and develops a peak output of 500hp and 640Nm of torque.

Other performance mods include a custom sports suspension set-up and light weight forged alloy wheels measuring 21 inches in diameter.

The interior can be fitted with a range of materials, from high-grade wood to carbon-fiber for the trim inserts, and a variety of upholstery choices in either leather or Alcantara are available to give the interior that extra touch.
