With its aggressive stance, classic lines and deep-throated growl, it'd take a really breathtaking array of exotic machinery to let a car like the Jaguar XKR go by unnoticed. Unfortunately for Jaguar, that's exactly what rolls up Lord March's lawn every summer for the Goodwood Festival of Speed. The stoic British marque has a long history of participation in the event, and came this year with its 225mph XFR and a host of rare classics. But apparently eager to make its mark, Jaguar turned up with a special-edition XKR, painting it a retina-burning shade of lime green with orange decals, just to make sure it got noticed.
The Goodwood Special upgrades the stock XKR with a lowered suspension, retuned exhaust, 21-inch alloys and satin graphite trim replacing the chrome. But the real treat is under the hood, where Coventry's finest have squeezed out a further twenty ponies from the supercharged 5.0-liter V8 for a total of 530 horsepower and 515 lb-ft of torque. Considering that the (anything but) ordinary 510 hp version rockets to 60 mph in just 4.6 seconds, the extra power promises to take the sport coupe into even more rarified territory. Unfortunately for the time being the Goodwood Special remains a one-off, but Jaguar is reportedly keeping its ear to the ground for enough feedback to offer a limited production run.
