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.
