As we have mentioned it before, Jaguar is gradually killing off the XK class, with no replacement planned for at least the next five or six years. They are giving the car a proper sendoff though, in form of a limited edition of 50 special XKR models, available only in the United States.

The Jaguar XKR Final Fifty Edition – how long it took for Jag to come up with that name, by the way – is inspired by the final edition of the iconic E-Type. In1974. Fifty E-Type roadsters were made, 49 in black over cinnamon trim and one in British Racing Green. The Final Edition XKRs, though, will only come in black.

They do, however, get some exterior and interior appointment to be distinguished over normal models, including louvered hood from the limited-production XKR-S GT model, a special badge on the center console and an inscribed doorsill treadplate.

Performance-wise, Jaguar XKR Final Fifty Edition comes as standard with both the Dynamic Pack and Performance Pack, meaning you get an aero kit consisting of side sills, a rear diffuser and larger rear wing, and that the top speed limiter has been loosened a bit. So the 510 horsepower supercharged engine can now take you up to 174 mph.

Other highlights of the Final Fifty include Adaptive Dynamics suspension with 10mm lower ride height, ‘Vortex’ 20-inch forged wheels, active exhausts, and special leather treatment with Diamond Sewn stitch patter.

There will be 25 Coupe and 25 Convertible Jaguar XKR Final Fifty Edition, and they will go on sale in America this summer.
