Pontiac re-defined the 2+2 idea with the Sunfire concept sports coupé. This hot-looking little four-seater features a set of unique door openings which use one-and-a-half doors on each side to facilitate access to the rear seats while allowing normal front seat entry and exit.

It is powered by a front-mounted 16-valve dual overhead cam 2-litre engine that delivers 190 hp and 205 ft/lb of torque. It also features fully independent suspension, anti- lock brakes and five-speed automatic transmission. The body is hi-tech carbon fibre and uses 20-inch front wheels with 21-inch rear wheels. The interior features all the latest electronics including a HUD, or Head Up Display.
