Recently introduced Jaguar XFR is now officially the fastest Jaguar in the history as it hits 225 mph at Bonneville Salt Flats speedway, Driven by racer Paul Gentilozzi. The only modifaications included removing speed limiter (well of course!) and adding a rear wing to keep the car on the ground while going that fast. XFR broke the record of 220mph set by a 90s XJ220.
