The Jaguar XKR Goodwood Special was a special one-off build created last year to explore the harder side of the XKR's character and allow engineers to explore some performance boundaries. While the Goodwood Special never eventuated into the long-rumored XKR-R, the special edition model itself has now entered production as the limited edition Jaguar XKR 75.

Built to mark the automaker’s 75th anniversary, the new Jaguar XKR 75 coupe will be built in a limited run of just 75 cars and will make its world debut early next month at the 2010 Goodwood Festival of Speed.

Jaguar engineers increased the power and torque of the regular XKR’s 5.0-liter supercharged V-8 to 522 horsepower and a stump-pulling 483 pound-feet of torque. While the limited edition model's top speed is electronically limited to 174 mph, the XKR 75's 0-60 mph acceleration time is reduced from 4.6 to 4.4 seconds compared to the regular XKR.

The increase in power is matched with revised suspension and handling upgrades, as well as a revised aerodynamic body pack with a front splitter, side sills extensions, a rear diffuser and larger rear spoiler. The XKR’s computerized Active Differential Control also adjusts to reduce steering sensitivity at very high speeds, further improving stability and driver control.

Other touches include red brake calipers, 20 inch forged alloy wheels, and an optional body graphic that runs along the side of the car. Inside, there’s charcoal trim with piano black touches.

This year’s Goodwood Festival of Speed kicks off on July 2.
