It’s hard to imagine ways to improve the sexy, speedy Jaguar XKR, but Jaguar seems to think it can. As proof, it has developed two option packages for the new 2011 XKR: the Black Pack and the Speed Pack. Check both boxes, and you get the 2011 XKR Special Edition. The optional Speed Pack starts with a less-restrictive top-speed governor, raising terminal velocity to 174 mph from 155 (both electronically limited). No changes have been made to the direct-injection engine. Styling changes include a new front splitter, side-sill extensions, a body-color rear diffuser, a taller rear spoiler, and chrome-finished hood nostrils and window trim. Red brake calipers are visible within spokey 20-inch “Kasuga” wheels that bear a strong resemblance to those on the Bentley Continental Speed. Finally, the Speed Pack can only be ordered on cars rendered in Ultimate Black, Polaris White, Salsa Red, Liquid Silver, Lunar Grey, Kyanite Blue, or Spectrum Blue.
