A good number of the updated Jaguar XKR's supplied action shots show the coupe sideways with a cloud of smoke in pursuit. While this alludes to variety of improvements for the 2010 model year, the most noteworthy must be the new engine -- a 5.0L V-8 with a Roots-type supercharger. Also on the new 2010 Jaguar XFR, the V-8, with 510 hp and 461 lb-ft of torque, eclipses the previous-gen 4.2L by 90 hp. Jaguar increases its performance claims as a result, dropping the 0-to-60-mph acceleration to 4.6 sec from 4.9 sec. A loss of one mpg in highway fuel economy is the only downside to the newfound power; the 2010 XKR returns 15/22 city/highway mpg.
The "JaguarDrive Selector" -- the much-ballyhooed silver shift dial that rises out of the center console in the XF -- makes an appearance for the first time in the 2010 Jaguar XK-Series lineup. Along with the new shifter come an electronically controlled suspension and differential systems. The former analyzes pitch and roll rates and compensates for them with dampening adjustments, as much as 100 times a second.
The 2010 Jaguar XKR retains its lightweight yet rigid all-aluminum monocoque chassis and comes in coupe or convertible form. And lest we forget, that optional convertible top will open or shut in 18 seconds. So this summer, when the 2010 XKR hits the market, look forward to a nice bit of fresh air in the cabin during all your sideways shenanigans.
