Making its debut at the 2011 Geneva Motor Show, the Jaguar 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 '300kph 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.
