LP640 price :
Engine comes as the major difference inbetween XK & XKR. Though it has a same kind of V8 engine, XKR has an addtionaly supercharger because of that Jaguar XKR can generate 420 horse power while Jaguar XK generates 300 horse power. Both cars have same 250 km/h speed limit.
But thers is a small minor risk in this car, because the speed is not enough downforce holding the car to the road. But somehow Ferrari 599 manages to have enough downforce and the special is this car isn't using spoilers or Wings to manage it.
