Oozing luxury and completely redesigned for 2011, the XJ Series has -- as its flashy edition -- the athletic XJL Supersport. The "L" identifies it as a long-wheelbase version, and the "Supersport" means it contains the explosive 510-horsepower, supercharged, 5-liter V-8 mated to a six-speed, driver-shiftable, automatic transmission.
Jaguar gives a zero to 60-mph time of 4.7 seconds and a top speed of 155 miles per hour. Despite this being the sportiest XJ, Jaguar pulled out all the stops to make it uber-opulent. Leather-covered semi-airline seats, wood accents and a leather headliner only top the grocery list of luxury and high-tech features.
