MG Rover Group is promising to reveal a "new high performance sports car" at next week's British motor show in Birmingham. The car should, of course, be the production version of the Qvale Mangusta-based luxury sports model first shown in 2001 as the MG X80 concept. MG Rover says the latest version is re-designed and lighter with more power. The company claims to have targeted the driving enthusiast with "extreme levels of performance with great potential for both road and track".
