Showcasing a new range of both performance and personalization potential for this scintillating Super Cat, the 2011 Jaguar XKR Special Edition will get star billing on the automaker's stand in Geneva. A stylish combination of two new Euro-spec option packages and some select extras turn it into the fastest and arguably most-striking XK variant produced to date.

What sets the 2011 Jaguar XKR Special Edition apart from its baseline XKR kin?

For openers, the car incorporates bits from both the new Speed Pack and the Black Pack upgrades. Although the eponymously named go-faster kit doesn't change the 510-horsepower or 461 lb.-ft. of torque generated by its standard 5.0-liter supercharged V8, it recalibrates the computer controller on the engine and six-speed automatic transmission and allows this ultra-XKR's electronically-limited top speed to rise from 155 to 174 mph. To keep it better grounded at those higher velocities, the Speed Pack also includes a revamped front splitter and a larger rear spoiler. While Jag mandates that all Speed Pack XKRs be confined to Ultimate Black, Polaris White, Salsa Red, Liquid Silver, Lunar Grey, Kyanite Blue and Spectrum Blue, each will also come with body-colored side sills and rear diffuser plus added brightwork on the grille elements, window surrounds, Power Vents and decklid. To finish the look, red brake calipers carrying an "R" logo peer out from behind special 20-inch Kasuga alloy wheels.

Available as an option for those seeking to endow their velocity-enhanced XKRs with a bit higher profile as they go streaking off into the distance, the Black Pack add-on brings its own cosmetic upgrades to the mix. Here, exterior colors are further restricted to Ultimate Black, Polaris White or Salsa Red, and most of the chrome trim gets redone in gloss black, which also is used on its 20-inch Kalimos alloy wheels. Inside, all Black Pack XKRs get trimmed in Charcoal leather hides accented with Dark Oak, Dark Mesh Aluminum or Piano Black dash and door trims.

Regrettably, Jaguar says it has no plans to bring either the XKR Special Edition or either of these specific upgrade packages to the U.S. However, it did confirm that a special "North America-only performance-oriented Limited Edition XKR" is in the works and will likely contain at least some of the elements found on the Geneva car. It's due to arrive here later this year to help support the automaker's 75th Anniversary celebration. Stay tuned.
