Arden has grown to become a specialist in the tuning of Jaguar products
The package includes a range of performance and styling upgrades - not that the 5.0-liter supercharged V-8 powered XKR was lacking in performance already, or in style. Under the hood, Arden’s engineers have managed to liberate some horses from the engine thanks to a new exhaust system. Featuring sport catalysts the new exhaust lifts power by 30 horsepower, bringing the final power output to a Lamborghini Gallardo Superleggera-toppling 540 horsepower. At the same time the torque figures are pushed up from the standard 461 pound-feet to 498 pound-feet of torque, enough to propel the Arden XKR Convertible to a top speed of 200 mph flat.
In terms of styling upgrades, Arden customizes the XKR Convertible with a new chrome grille up front, and modified air intakes. At the rear, a new diffuser houses the custom-installed quad-exhaust pipes from the new exhaust system. At the corners, 21 inch Sportline alloy wheels that also featured on Arden’s previously tuned XKR Coupe can be found. Other upgrades for the Coupe, such as big brakes, a leather sports steering wheel and a lowering system will likely be available for the Convertible as well, although Arden hasn't given any official word to that matter yet.
