Finally, an engine update! Gone are the days when the performance was limited due to the 4.2 liter supercharged V8. The new XKR is updated with a 5.0 liter supercharged V8. (510bhp and 461lb-ft vs. 385bhp and 380lb-ft). And I think that Jaguars are one of the best looking cars in the world. More info here.
