2010 Jaguar XFR achieves top speed of 225 mph at Bonneville Salt Flats
Wednesday, January 14th, 2009
The latest Jaguar XFR, which was created to compete with the Bmw M5, Mercedes-Benz E63 AMG and the Audi RS6, claims that there is performance behind its appearance.
From a speed test at the Bonneville Salt Flats in Utah, the XFR clocked in at a top speed of 225.675 mph (363.188km/h) making it the fastest Jaguar since the XJ220 supercar hit the 217.1mph (349km/h) mark back in 1992 making it the fastest car at the time.
The top speed was achieved through a remapping of the ECU, revised air intake and exhaust system and modified supercharger settings with minor aerodynamic and safety enhancements just to conform to a Bonneville run. The engine was virtually untouched and the six-speed auto transmission was standard to the model, as well as gear rations. The standard Jaguar XFR has a top speed of 155 mph (250 km/h) which is electronically restricted. source
