Performance-minded Chicago Jaguar enthusiasts might have another model to yearn for come this year’s Goodwood Festival of Speed, assuming recent Web chatter is accurate.

The new jaguar in Chicago in question is rumored to be an extreme version of an already-potent 2010 XKR coupe sporting the brand’s 510-hp supercharged 5.0L AJ-V8 with a few alterations on hand. A couple of the features will include a throatier exhaust system and a similarly intimidating front fascia with a new satin graphite grille.

“The car is called the Goodwood Special XKR, and has been designed to explore the harder side of the XKR’s character, and explore some of the performance boundaries,” said Jaguar’s head engineer Mike Cross to Piston Heads.

Jaguar’s award-winning vehicles are well-known around the world. Jaguar is the world’s leading producers of beautiful fast cars. The exciting new range of premium luxury vehicles available for the Chicago certified preowned Jaguar dealership will include the Jaguar XF Chicago, XFR and XKR.

Let me be one of the first to say that I would do whatever it took to get behind the wheel of a new Jag, especially one as striking as the 2010 Jaguar XF Premium sedan. If you’ve driven a Jaguar XF sedan once, be it the base XF, the tested XF Premium, or the exotic XFR, you’ll gladly drive one again.

The trick for luxury brand Jaguar, and its many rivals, is to heed government pressure to maximize fuel efficiency without weakening their base characteristics.

When referring to the rear-wheel-drive XF Premium, its apparent Jaguar’s designers tried to deliver more fuel economy, without sacrificing beauty, power and speed. The XF Premium comes with a new 5-liter, 385-horsepower V-8 engine to satisfy motorists craving power.

The car is a timeless piece of artwork on wheels, a luxury car that maneuvers toward honoring practicality while maintaining its aesthetic appeal and menacing charm.
