The XJ gets a subtle exterior tuning and some additional power under the hood for the 5.0 liter V8 supercharged model.
German tuner Arden does the Jaguar XJ 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.
