Arden’s Jaguar XF Based AJ 21 with up to 550 HP

Arden has finally released real life images and mechanical details on its latest creation, the Jaguar XF based AJ 21. The top of the line version of the AJ 21 gets a supercharged V8 engine stroked out from 4.2-liters to 4.5-liters delivering an output of about 550 HP, which should be more than enough to take the “wildcat” into M5 territory.

Although that’s the Jag to go for, the German tuning firm also offers a 4.5-liter version for both the naturally aspirated and supercharged 4.2-liter V8 engines, increasing output by 80 HP to 380 HPand 500 HP respectively. In the case of the 2.7-liter V6 diesel engine, Arden’s tuning kit bumps power from the standard 207 HP to 250 HP. Other modifications include a specially developed custom sport suspension from Arden combined with light weight 21-inch alloy wheels. -Continued

The Jaguar XF’s exterior has received an extensive treatment that includes a full bodykit with a new front bumper with larger air vents and integrated LED daylights, new side sills that incorporate functional air inlets for better cooling of the rear brakes, a relatively discreet rear lid spoiler and a rear diffuser. Look a bit closer at the front end and you may notice the jaguar ornament on the hood along with the revised the radiator grille which is now more oval-shaped.
