1957 Pontiac Bonneville Convertible

To put Pontiac on the same page as Cadillac, the design staff at GM made the 1957 Bonneville. It was a fully-loaded convertible or coupe that came with the fuel-injected V8 engine. Production of the Convertible was limited to one per dealer so it also became the most exclusive model in the 1957 range.

The first production Bonneville was released to the public in January of 1957. This followed a Motorama dream car of the same name which was first shown in 1953. Priced at more then double Pontiac's previous Star Chief Convertible, the Bonneville was very highly optioned. The list included, but is not limited to a power top, power antenna, power steering, power brakes, power windows, eight-way power seats, leather upholstery and a Wonder Bar radio. The only two options were the factory air and continental tire kit.

Despite all the grandiose appointments, the Bonneville was no slouch on the road. It was one of the first cars to use Rochester mechanical fuel injection which was rated as '347/310 HP'. This meant 0 to 60mph in 8.1 seconds and a top speed of 101.6 mph.

Before the redesigned Bonneville hit in 1958 Pontiac produced 630 units.
