Official: Jaguar XFR is the fastest Jaguar ever, previews XFR S special ed
Secret speed trials on the Bonneville salt flats in Utah confirm that the Jaguar XFR is the fastest car that Jag has ever built, clocking a top speed of 225.675mph. And it previews a special XFR S coming in late 2010 too
"The Jag XFR is officially rapid"
In preparation for the run, the XFR was given an aerodynamic makeover, including the addition of a massive rear wing and a parachute just in case it all went wrong.
While the car’s engine internals and gearbox were left standard, a revised air intake, exhaust system, a beefed up supercharger and remapped ECU liberated 600hp from the car’s V8.
Just like the Jaguar XKR S, this leaves the door open for the rumoured Jaguar XFR S that Jaguar sources have alluded to being built in limited numbers towards the end of the car's life, arriving in late 2010.
For now, credit is due to Paul Gentilozzi, a Jaguar racing specialist who also owns motorsport preparation company Rocketsports Racing, who undertook the record-breaking XFR run.
He smashed the existing company record of 217.1mph set in the Jaguar XJ220 in 1992.
