Autocar has given Jaguar XFR 5 stars

The Jaguar XFR is a crushingly effective super saloon. Its 503bhp supercharged V8 has relentless pace, and it's the prettiest car in its class.

The XFR builds on the now familiar XF saloon recipe but is powered by a 503bhp direct injection supercharged V8. It also gets substantial chassis changes, including different spring rates, a newly developed continuously variable electronic damping system and a new electronically controlled rear differential.

Inside there are further additions such as special dials, dark wood and more heavily bolstered, but extremely comfortable, seats.

The supercharged V8 in the Jaguar XFR is an absolutely magnificent engine. It makes the car almost indecently quick.

The new XFR also benefits from enhancements to the steering over the standard car.

The visual changes are subtle but effective. There’s a redesigned, XJ-esque front end with a more aggressive look and added air intakes. It also gets flared sills, a discreet boot lid spoiler and standard 20-inch alloy wheels.

The Jaguar XFR is the British company’s rival to the BMW M5 and the Mercedes E63 AMG.
