The Pontiac Stinger concept introduced in 1989, featured all-wheel drive, carbon fibre body panels and, with the exception of the windshield, removable glass panels. The distinctive aerodynamic grey-and-green body could be transformed from two-door enclosed transportation to an open-air vehicle for all-season fun, utility and convenience.
Pontiac’s concept vehicle for 1989 was aimed directly at the youth market and called "Stinger". As an all-season multipurpose prototype, the Stinger rode on a short wheelbase chassis, and the two-tone, green and gray carbon-fiber body could be modified from a closed coupe to an open air fun-in-the-sun driving. The windshield and glass panel doors could be removed, and a 170 horsepower, 3.0-liter 4-cylinder engine propelled the all-wheel drive system. Mated to the Super-Duty-based engine was a Hydra-Matic gearbox. When needed, the pneumatic suspension would raise the car 4-inches.
