Just check out the details. A supercharged, 5.0-liter with direct-injection developing 510 hp sits under the hood. That impressive output is routed through a beefed up version of the superb six-speed ZF automatic transmission with paddle shifters. Mix in new adaptive dampers supplied by Bilstein and trick electronic rear differential that transfer 90% of torque across the rear axle and Jaguar has a car that should worry the BMW M5 and Mercedes E63 AMG. Jaguar chassis guru Mike Cross helped make the present XF Supercharged a very special car to drive (and a 2009 All-Star) and he gave us a confident smirk when we asked him how much better the R version is to drive. We can't wait to have a go later this winter.
