Jaguar's XKR is already plenty quick, what with 510 hp on tap and an electronically limited top speed of 155 mph. But buyers hankering for a faster pussycat will love what the automaker has in store for the 2011 XKR Coupe.
The updated XKR Coupe will now be available in what Jaguar calls the "Speed Pack." As its name suggests, the option is all about pushing the speedometer needle past 155. The secret, it seems, doesn't lie with brute power -- output from the supercharged 5.0-liter V-8 remains 510 hp and 461 lb.-ft. of torque. Instead, Jaguar says it was able to push the top end to 174 mph simply by recalibrating both the engine and transmission controls.
In order to help keep the XKR glued to the ground at such speeds, the Speed Pack adds a unique body kit designed to improve the car's aerodynamics. The tall front fascia gains a modified splitter, while the rear spoiler grows in size. An active rear differential is now standard equipment -- Jaguar claims it helps reduce steering sensitivity when at higher velocities -- as are 20-inch aluminum wheels.
In typical Jaguar fashion, the Speed Pack also adds some cosmetic flair to the performance package. XKR Speed Pack models get a chrome finish to the window surrounds, mesh grille inserts, fender vent trim, and the trunk applique. Customers can choose from one of six colors, and if so desired, a side stripe -- somewhat reminiscent of those applied to the Porsche 911 GT3 RS -- is optional.
For those who desire a little more luxury within the cabin, customers can also spring for the "Black Pack" (white car), available only on XKRs equipped with the Speed Pack. The Black Pack trims the window surrounds and grilles in a piano black finish, while adding charcoal leather to the interior.
Look for the 2011 XKR Speed Pack to make its world debut at the 2010 Geneva motor show in March. Although we've yet to hear from Jaguar regarding the Speed Pack's availability in North America, at the very least, look for a slightly modified 2011 XKR -- complete with red brake calipers and run-flat tires -- to arrive this fall.
