Jaguar have released details on its 2008 XJ Series sedan ahead of its official release at the Geneva Motor Show next week. The car features a few minor design changes, unfortunately no changes have been made to the engine. The front end has been revised with a new air inlet below the grille and new fog lamps in a redesigned bumper. The seats have also been redesigned giving passengers in the rear more leg room. Three new colors are now available as well as three new wheel designs. It will be available for purchase this spring.
