Making its debut at the Geneva Motor Show 2011 (with the convertible coming in 2012), the XKR-S is the most extreme expression yet of Jaguar's passion for building beautiful, fast cars. For the first time with a series production car, Jaguar gains entry to the exclusive '300km/ h club' thanks to the effortless performance of the supercharged 5. 0-litre AJ-V8 engine. A revised fuelling map means the direct-injection powerplant now produces 550PS and 680Nm of torque. Extensive recalibration has ensured that power delivery and performance are seamless, contributing to a 0-60mph time of 4. 2 seconds. The Performance active exhaust encourages and rewards the enthusiastic driver with dramatic, motorsport-inspired aural feedback. The XKR-S also required aerodynamic modifications to achieve its 300km/ h top speed in the unruffled manner expected of a Jaguar and has been designed solely with an eye for purity of line and singularity of purpose. As the XKR-S approaches its top speed, there is a requirement to channel air cleanly over, around and under the car in order to maintain stability and ensure balanced downforce front and rear. An overall reduction in lift of 26 per cent has been achieved.

This stunning example arrives with black leather recaros with reims blue stitch, brake upgrade program, heated front windscreen, heated steering wheel, keyless entry, power 16-way passenger seat adjustment, SVR carbon fibre rear spoiler, 186mph speed limitation, suede cloth XKR-S steering wheel, body styling kit sport, grey embossed brake calipers, digital audio broadcast, R performance exhaust pipe, metallic finish foot pedal, R-S leather edged floor mats, black gloss grille, premium sound system, rearview camera, gloss black side vents, sport-tuned suspension, auto-dimming rearview mirror, Bluetooth, gloss black tailgate, cruise control, engine torque 680 newton metre, interior contrast piping, reverse parking aid, ebony seatbelts, upgraded sports front knuckle, 8 high series radio speakers and blue stitching.

The interior of the Jaguar XKR-S offers that same excitement that the exterior does, matching the drive to offer a pure, exhilarating experience for both driver and passengers. Opted from factory with the black leather recaro seats with blue stitch detail and carbon look leather detailing, black leather dash, carbon look leather door card inserts, flint grey carpets with Jaguar mats, black leather centre armrest and drivers tunnel that surround the centre console. The interior space is finished off in fantastic fashion by the piano black centre console and the XKR-S exclusive dashboard insert.

The styling of the XKR-S is dramatic in every sense, despite being designed to ensure the greatest possible performance Jaguar has done its usual trick and made a truly stunning X150. Created through several hours of wind tunnel testing the flagship XKR undertook several exterior modifications to ensure it was the ultimate car. Presented in Jaguar's famous Polaris White and optional dark blue roof the XKR-S looks truly staggering. Further exterior details come in the form of the XKR-S exclusive fixed rear spoiler with carbon centre piece, the colour coded oval air intakes, lower front splitter which was all designed to created greater high speed stability. The XKR-S also has wider sills than the standard XKR and also comes with the colour coded bonnet vents and that quad exhaust at the rear that makes such a great soundtrack.
