The Pontiac Bonneville Hardtop is a saloon (sedan) with 4 doors and a front mounted engine which transmits its power through the rear wheels.
Powering the Pontiac Bonneville Hardtop is an overhead valve, 7.5 litre naturally aspirated 8 cylinder powerplant, with 2 valves per cylinder that provides power and torque figures of 360 bhp (365 PS/268 kW) at 4300 rpm and 678 N·m (500 lb·ft/69.1 kgm) at 2700 rpm respectively.
A 3 speed automatic gearbox supplies the power to the wheels.
