Arden, an expert in tuning high-end British cars, released details of their upgrade package for Jaguar’s powerful convertible, the XKR-S. The package includes both visual upgrades, and a performance kit that boosts the output of the Jag’s Supercharged V8 engine.

Arden’s treatment for the engine increases the power from the standard 550 horsepower and 680 Nm, to a massive 645 horsepower and over 800 Nm of torque. That will make the already vivid performance of the XKR-S much more exciting.

On the styling front, some dental work in from of mesh grilles plus red lipstick and a new chin spoiler give the old gal a whole new look, while new side skirts and revised rear bumper with four large tailpipes make it look sporty. 21-inch Arden wheels are also included.

For the interior Arden provides different wood and carbon trims, leather and Alcantara upholstery, and and aluminum sport pedals.
