The Jaguar XKR Convertible has been tweaked by German tuner Arden.
The 2010 model XKR Convertible gains 29bhp and 37lb ft of torque, meaning a total output of 532bhp and 498lb ft of torque.
In addition, the speed limiter has been removed (but no top speed is quoted) and a sport suspension kit with stiffer shock absorbers has been fitted.
Other changes are cosmetic: the front grille and air intakes have been replaced with handmade, chrome-plated stainless steel grilles, and there's a new rear diffuser that houses the new sport exhaust system. The car also runs on 21-inch Sportline alloys.
No prices have been released.
