Arden has already a tradition in modifications for the latest XK model from Jaguar. For the XK AJ 20 Coupe, Arden tuning means bigger displacement engine and offers pure, unadulterated Jaguar enjoyment plus that distinguishing Arden touch.
Jaguar fits the XK as standard with a powerful 4.2 l V8 with 298 bhp and 303 lbs-ft. Arden rebuilds this eight-cylinder engine from scratch and sharpens the claws of this big cat by increasing its displacement. The displacement increase to 4.5 l is achieved by fitting a crankshaft specially produced for Arden, along with new con rods and pistons.
Arden optimises the lubrication and the cooling and, in doing so, guarantees a long service life of the components, as it also does through its more than 20 years of experience in the field of Jaguar engine tuning. In conjunction with the modified intake and exhaust systems and sports catalytic converters, the fully recalibrated EMS produces an emphatic but harmonious power boost, whilst retaining the original exhaust gas classification.
Drivers’ eyes light up even brighter when they see the Arden’s compressor version, which puts the Krefeld tuning specialist one step ahead of the British manufacturer, since Jaguar doesn’t currently offer a supercharged engine. Arden elicits an impressive 480 bhp and an awesome torque of 640 Nm at 3,850 rpm from its supercharged 4.5 l V8 engine. The supercharged XK accelerates 0.5 seconds faster to 60 mph than its Arden naturally aspirated counterpart, and as much as a clear 1.4 seconds faster than the production version. The top speed is 177 mph.
With the XK AJ 20 Coupe, Arden contrasts the more delicate appearance of the production version with a muscular look. At the front, the coupe is given an impressive "face" by fitting the Arden front spoiler featuring large air inlets. New side sills, also incorporating air inlets, continue the front design and make the car look lower to the road. Arden swaps the side vents in favour of its own, colour-contrasting versions. Cooling openings in the right and left-hand side of the bonnet (also colour-contrasting like the side vents) create a more sporty appearance. The rear end constitutes the logical conclusion defined by the front design.
Like the front section, the rear apron also features cooling openings. To effectively reduce the lift and to make the XK more sure-footed, Arden equips its XK AJ 20 Coupe with a rear spoiler, which blends perfectly into the basic design. A must for every Jaguar enthusiast is the patented Arden bonnet ornament, whose base has been specially angled for the new XK. It is characterised by its attention for detail and both its visual and technically perfect craftsmanship. Its anti-theft system prevents it from being stolen and it is TÜV approved. Consequently, in the event of a collision, it gives way and, in the case of a more severe impact, it even comes away completely, thus minimising the risk of injury.
The Arden XK features new 21" wheels (FA: 9 x 21" with 255/35R21", RA: 10 x 21" with 295/30 R 21") produced using state-of-the-art machines in the exclusive and further advanced Arden "Sportline" design. In conjunction with the Arden set of suspension springs or a sports suspension, they constantly optimise the road contact and successfully round off the appearance of the Arden XK AJ 20 Coupe.
Arden has also proven to be an expert when it comes to the interior. For instance, the in-house upholsterer and Arden designer joiner’s workshop are responsible for numerous styling components. Anyone who prefers the famous British noblesse can order high-grade wood interior trim inserts. Motor racing fans will opt for sophisticated carbon-fibre trims to adorn the cockpit. Upholsteries in leather or Alcantara lend the car an extra special luxurious atmosphere.
