Jaguar XKR - Review: Anybody with a pulse will feel it quicken when gazing upon the 2007 Jaguar XKR. From the fender vents to the hood louvers to its tight proportions, its sleek lines promise performance. Looks have never been Jaguar’s shortcoming, but previous XK’s delivered an underwhelming driving experience that failed to deliver on the styling’s promise. This new XKR largely changes that. Its supercharged powertrain is a masterpiece, the suspension is a good compromise between handling and that silky Jaguar ride, and from the driver’s seat there are few cars that fill the high-performance GT role as well as this car. Despite this, we were distracted by several refinement shortcomings in the XKR that buyers may not accept on a $90,000 car.
