Detroit NAIAS 2009: Jaguar XFR hits 225.675 mph at Bonneville

Jaguar announced that during a secret speed trial at the Bonneville Salt Flats in Utah, a Jaguar XFR prototype recorded a top speed of 225.675 mph, making it the fastest Jaguar ever - of course as you can see from the picture the running prototype had some minor aerodynamic and safety modifications to meet the requirements for Bonneville.

Power comes from the same supercharged 5.4L AJ V8 GEN III seen in the production model. Paul Gentilozzi, owner of Rocketsports Racing drove the XFR to its record-breaking run beating Jaguar’s previous speed record of 217.1 mph.

Modifications to the Bonneville model included a remapped ECU, modified air intake and exhaust system and a revised supercharger setting. If you plan on buying the production 510-hp Jaguar XFR that hits dealer ships later this year - don’t plan on topping the electronically limited top speed of 155 mph. Just enjoy going from 0 to 60 mph in 4.7 seconds.
