Making its worldwide debut in Geneva, the Jaguar XKR-S is ultimately an upgraded special edition version of the standard XKR Coupe that will be produced in a mere 200 units, all of which will be available only in Europe. Whilst the XKR-S retains the XKR’s powertrain – 420Hp 4.2litre supercharged V8 matted to a 6-speed auto gearbox with manual paddle shifts, thanks to a recalibrated engine management and improved aerodynamics, the XKR-S reaches an electronically limited top speed of 174mph (280km/h) – 19mph (30km/h) faster than the XKR. 
Furthermore, Jaguar’s engineers enhanced the XKR’s driving dynamics by revising the suspension with bespoke springs, dampers, anti-roll bar and recalibrated Computer Active Technology Suspension (CATS). The XKR-S also features an Alcon R Performance braking system with red monobloc six-piston callipers and 400mm brake discs at the front, 350mm at the rear.
Appearance-wise, finished in an “Ultimate Black” metallic color the XKR-S is distinguished by the revised front air-splitter and side sill-extensions, revised rear spoiler and rear bumper with unique diffuser panel and unique 20" lightweight Vortex alloy wheels. –Continued after the jump
