The fastest Jaguar ever

Jaguar announced that during a secret speed trial at the legendary Bonneville Salt Flats in Utah, an XFR prototype recorded a stunning top speed of 225.675mph (363.188km/h), making it the fastest Jaguar ever.

The car - powered by the all-new AJ-V8 Gen III engine - beat Jaguar's previous speed record of 217.1mph (349.4 km/h) set in the XJ220 in 1992.* Paul Gentilozzi – the owner of Rocketsports Racing who successfully led the Jaguar XKR to five series victories between 2001 and 2006 in the Trans Am series in the USA - drove the car on the record-breaking run.

Running with minor aerodynamic and safety modifications to meet the requirements for a Bonneville run, the 225mph top speed was achieved with additional horsepower liberated by a remapped ECU, a modified air intake and exhaust system and revised supercharger settings. No internal engine components were changed and the six-speed automatic transmission was standard, including the gear ratios.

Jaguar has also revealed the new XKR and XFR at the 2009 North American International Auto Show - two cars that are true to the heritage of Jaguar's legendary performance, delivering a superb balance of high performance, dynamic ability and refinement.
