Pontiac Grand Prix
The Pontiac Grand Prix is an automobile that was produced by the Pontiac division of General Motors. First introduced as part of Pontiac's full-size model offering for the 1962 model year, the Grand Prix name was also applied to cars in the personal luxury car market segment and the mid-size offering, slotting below the large Bonneville in the company's lineup.
Picking up where the Pontiac Ventura model left off, the Grand Prix first appeared in the Pontiac line for 1962. It was essentially a standard Pontiac Catalina coupe with minimal outside chrome trim and a sportier interior (bucket seats and a center console). The performance-minded John De Lorean, head of Advanced Engineering at Pontiac, contributed greatly to the development of both the Grand Prix and the GTO. Early models had full access to the Pontiac performance option list, including the factory-race Super Duty 421 powertrain installed in a handful of 1962 and 1963 cars.
The full-size Catalina-based Grand Prix did very well through the 1960s, and is often credited with the move towards minimal exterior trim seen in the 1960s. Yet its clear resemblance to the other full-size Pontiacs caused some to consider it a lesser model than the other personal luxury cars. At the same time, the Grand Prix had a much stronger performance image than its competitors.
Revised sheetmetal with more rounded wasp-waisted styling highlighted the 1967 Grand Prix and other full-sized Pontiacs, along with the addition of a new Grand Prix convertible. Also new to the GP were concealed headlights with horizontal mounting (all other full-size '67 Pontiacs retained the vertical headlights for one more year), concealed windshield wipers and ventless front windows on hardtop coupes. Out back were louvered taillights similar to those found on the GTO.
Inside, Strato bucket seats and console were still standard equipment with Morrokide vinyl or cloth upholstery, or a no-cost optional notchback bench seat with either trims. Other changes included a revised instrument panel and door panel trim.
Under the hood, the 389 V8 was replaced by a new 400 cu in (6.6 l) V8 with four-barrel carburetor, dual exhausts and 350 hp (260 kW). Similarly, the 421 V8 was replaced by a new 428 cu in (7.0 l) V8 rated at 360 hp (270 kW) or an HO version with 376 hp (280 kW) - both with four-barrel carburetors. Both the 400 and 428 V8s were basically bored out versions of the older 389/421 block but with various internal improvements including bigger valves and improved breathing capabilities.
New this year was a dual master-cylinder braking system and optional front disc brakes along with Rally II wheels. Also new for 1967 was an energy-absorbing collapsable steering column. Plus, Pontiac added an 8-track Stereo tape player.
The Grand Prix convertible would be a one-year only offering and dropped after this one year.
