Significantly, the XFR, powered by the all new AJ-V8 Gen III engine, has dethroned the XJ220 which in 1992 set a speed of 349.4km/h.
With minor aerodynamic modifications and changes for safety, the XFR managed to crack 363.188km/h - quick in anyone's language. To enable it to breathe a little better, it was supplied with a remapped ECU, some intake and exhaust changes, and revised supercharger settings.
However, internal engine components were untouched, and the gearbox, along with ratios, was unfettled.
Paul Gentilozzi, owner of Rocketsports Racing who won five series in Trans Am between 2001 and 2006, piloted the car on its record-breaking run.
Gentilozzi said: "During my career, I've raced worldwide from the southern tip of New Zealand to Le Mans. Along the way, I have been privileged to drive and own so many exciting cars but I've never driven one that was as exciting to drive fast as this Jaguar."
