The Pontiac Grand Prix was born in model-year 1962.
The first Grand Prix generation lasted through model-year 1968 on GM’s B-body platform, before switching to a stretched platform in 1969 dubbed the G-body.
Through the first two generations, the Grand Prix was always powered by a large V8 engine, ranging on the small end from a 6.4L, 389-cubic-inch V8 that churned out 303 horsepower, up to a 7.5L, 455-cubic-inch big block in the second-gen, early ’70s models. But because of a corporate-wide decision to build engines for lower-octane rated fuels, the second-gen engines were given lower compression ratios, which limited the power they produced from the factory.
The Pontiac Grand Prix remains an iconic piece of American automotive history and beloved by Pontiac enthusiasts.
