Jaguar adds more power to the XF’s current range topper and a new topper to the XF’s current range.
It hasn’t even been on sale for a year, but Jaguar is already upgrading the power of its 10Best-winning XF for 2010. Apparently, Jaguar has deemed the 420 hp and 5.0-second 0-to-60-mph time of the supercharged XF insufficient. To fix this “problem,” Jaguar is introducing a 5.0-liter version of its familiar 4.2-liter V-8 and a new top version of the XF dubbed XFR.
