Geneva Preshow: New Hardcore Jaguar XKR-S with 550HP V8

Exactly one year after the introduction of the updated XKR, Jaguar is returning to the Geneva Motor Show with its most potent mass production car ever, the new XKR-S which comes with an uprated supercharged V8 engine, overhauled suspension and new aerodynamic enhancements.

The XKR-S is fitted with modified version of Jahuar's 5.0-liter supercharged V8 producing 550-horses and 680Nm (501 lb-ft) of peak torque, an increase of 40HP and 70Nm over the standard car. That's enough power to offer the XKR-S a top speed of 186mph (300km/h) and a 0-60mph (96 km/h) sprint time of 4.2 seconds, with 0-100mph dismissed in just 8.6 seconds.

According to Jaguar, the new XKR-S is also the only car in its class that emits less than 300g/km CO2.

Alongside the engine upgrades, the British firm's engineers also made changes to the suspension and reprogrammed the Adaptive Dynamics system, while the XKR-S rides on a new set of lightweight alloy wheels shod in performance tires.

As you can see from the pictures, the XKR-S is distinguished by a new aerodynamics package with a more aggressive looking front bumper, re-profiled side skirts, additional air vents on the hood and bumpers, a large rear wing and a redesigned rear bumper housing a diffuser and quad tail pipes.

“The XKR-S is a bold and exciting new model for Jaguar,” said Adrian Hallmark, Jaguar’s new Global Brand Director. “We expect to attract both loyal and new Jaguar driving enthusiasts who still want the comfort, opulence and class only a Jaguar can offer, combined with inspirational performance.”

Jaguar said it will release full details and images the XKR-S at the Geneva Show on March 1.

Jaguar XKR Goodwood Special with 530HP V8: New Photo Gallery

If you made it to this weekend's Goodwood Festival of Speed (July 3-5), there's no way you could have not noticed Jaguar's special edition XKR. The one-off performance model that was purposely built for the event was painted in an extremely distinct lime-green color while the coupe also featured special exterior graphics in gray and orange.

Other styling tweaks that differentiate this model over the standard 2010 XKR facelift include the 21-inch alloys and the satin graphite detailing to the front grilles, door mirrors, rear signature blade, side window surrounds, headlights and bonnet louvres.

What's more is that Jaguar's engineers fiddled around with the XKR's supercharged 5.0-liter V8 that in standard form makes 510HP and 625Nm or 461 lb-ft of torque launching the sports coupe from standstill to 60mph (96km/h) in 4.6 seconds. In the XKR Goodwood Special, output is lifted to 530 horsepower and torque to 700Nm or 516.2 lb-ft.

The special edition XKR also features a lowered suspension and a tweaked exhaust system for a louder and more intimidating sound. Jaguar said that that the XKR Goodwood Special is a one-off model but we gather that if there's enough interest, the British automaker may launch a limited run series in the near future.
