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 ‘300kph club’ (186mph) thanks to the effortless performance of the supercharged 5.0-litre AJ-V8 engine. A revised fueling map means the direct-injection powerplant now produces 550hp and 502 lb/ft of torque.
Extensive tuning has ensured that power delivery and performance are seamless, contributing to a 0-60mph time of 4.2 seconds. The active exhaust encourages and rewards the enthusiastic driver with dramatic, motorsport-inspired aural feedback.
The AJ-V8 joined this illustrious list from the moment the first one was fired into life but in
the XKR-S it is presented in its most potent form to date. Now in its third iteration and with the addition of supercharging, the all-aluminum four-cam powerplant delivers not only extreme performance but also improved efficiency thanks to the technologies incorporated into it, including spray-guided direct injection (SGDI) and dual independent variable cam timing (DIVCT).
Nestling in the ‘V’ of the cylinders is a Roots-type twin vortex supercharger and two intercoolers that help provide the XKR-S with such urgent motive power. This sixth-generation forced induction unit is 20 percent more thermodynamically efficient than its predecessor, while the intercoolers feature their own water-cooling circuit to reduce the temperature of the pressurized air to optimize power and efficiency.
