Pontiac Grand Prix

Overview
The 1988-1996 Pontiac Grand Prix is a First Generation W-Body car. It replaced the rear-drive G-body Grand Prix. The Cutlass Supreme was only available as a 2-door and featured high-tech electronic instrumentation and a sleek, sporty appearance. The Grand Prix was marketed toward a younger target market than its sister cars, the Oldsmobile Cutlass Supreme and Buick Regal. The standard Grand Prix powerplant was a 2.8L multi-port fuel injected V6 producing 130HP and 160 ft-lbs of torque. In 1990, a 4-door Grand Prix was introduced.
