Jaguar to Show Hopped-up XKR, 225-mph XFR at Goodwood

At this week’s Goodwood Festival of Speed in the U.K., Jaguar will show off two modified versions of new cars.
The Bonneville XFR Prototype is the fastest Jaguar ever. A regular XFR is electronically limited to just 162 mph, but the prototype hit 225 mph at the Bonneville Salt Flats in Utah. To make the power needed for the high-speed run, the XFR scored a new intake and exhaust, modified supercharger, and remapped ECU, although the six-speed automatic transmission was untouched. The body received “minor aerodynamic and safety modifications.”
Also present will be the Goodwood Special XKR. Based on a 2010 XKR, the Goodwood Special gets lime green paint with funky "XKR" graphics, 21-inch wheels, lowered suspension, and a “louder” exhaust. There are also graphite accents on the headlights, mirrors, and front grille inserts. Somehow we doubt we’ll see these options in a Jaguar dealership.
Jaguar will also bring three historical race cars: the XJ13, the 1957 Long Nose D-type, and the C-type.
