Jaguar XFR Prototype does 225mph at Bonneville

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.

No offense, Jaguar...but "additional horsepower liberated by a remapped ECU, a modified air intake and exhaust system and revised supercharger settings. " does not a production car make. Still, impressive speed.
