The XJ gets a subtle exterior tuning and some additional power under the hood for the 5.0 liter V8 supercharged model
The Arden XJ 22 comes with an understated body kit which includes a mesh grill made of stainless-steel, LED fog lights and the new Arden hood ornament.
Arden also supplies its own sport suspension, stainless-steel quad sport exhaust and performance brakes.
Under the hood, Arden is outputting 605 PS (445 kW) from the 5.0 liter supercharged V8 engine - promising a 0 to 100 km/h sprint of 4.9 seconds. That's up a substantial amount from the series 375kW (510 bhp) and 625 Nm.
The German tuner also supplies new 21-inch alloy wheels and some interior upgrading which includes a leather or Alcantara upholstery with carbon, chrome or wood trimming and a new dynamic interior lighting system.
The tuning package is also available for the XJ 3.0L V6 diesel, although Arden doesn't specify any engine tuning for that model.
