Jaguar finally released more specs and details on its high-performance XKR 75, which is scheduled to make its much heralded debut at the 2010 Goodwood Festival of Speed on July 2. The special edition XKR 75 super coupe celebrates Jaguar’s 75 years in the auto industry.

As the name suggests, only 75 units of the car will be produced. The new special edition XKR 75 is powered by a 5.0 liter supercharged V8 which received a power boost as it is now capable of generating 523-hp and a maximum torque of 483 lb-ft. (655Nm compared to 625Nm on the XKR). With these figures, the car can go from 0 to 62 mph in 4.4 seconds (compared to 4.6 seconds for the XKR). The car’s top speed is electronically limited to 174mph.

As for the exterior styling, the new car features the Stratus Grey finish. The revised aero kit adds a front splitter, side sills extensions, a rear diffuser and larger rear spoiler in order to increase balance and reduce lift. Other new features include red brake calipers that provide contrast to the eye-catching 20-inch gloss Vortex forged lightweight alloy wheels with a dark technical finish and diamond turn. An optional body graphic that runs from the front bumper to the rear haunches completes the new package.

The XKR 75 also gets a revised suspension as well as handling for enhanced agility and precision. Inside, the exclusive add-ons include charcoal leather dressed up with ivory stitching, gloss piano black finish to facia and center console and a Jet suede-cloth headlining.
