XFR fastest Cat yet

Published:

AS PART of the promotion of its new flagship performance XF model, Jaguar has revealed that, during a secret speed trial at the legendary Bonneville Salt Flats in Utah, an XFR prototype recorded a top speed of 225.675mph, making it the fastest Jaguar ever.

The car – powered by an all-new V8 engine – beat Jaguar’s previous speed record of 217.1mph, set in the XJ220 in 1992.

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.

The new XFR is powered by an all-new supercharged five-litre V8 engine developing 510 horsepower. The XFR can accelerate from standstill to 60mph in just 4.7 seconds and is capable of reaching an electronically limited 155mph.
