Grand Prix background and what was new in 1965
The Grand Prix as a model
The Pontiac Grand Prix was first introduced in 1962 as Pontiac’s answer to the Ford Thunderbird, slotted as a luxury, performance, mid-size car, between the larger Bonneville and the smaller Tempest in the Pontiac lineup.
The 1965 Grand Prix in context
The 1965 Grand Prix was the fourth of the B-body based 1st Generation (1962-1968) with a more rounded body-styling than the 1964. The long, low, clean, wide look of the 1st Gen’s was a break from the bulkier, heavily chromed, larger tailfin cars of the 50’s.
65 vs 64 Front
The “eyebrow” lip over the top of the vertical dual headlights remained but each of the split grilles was divided into three horizontal rectangles with the parking lights contained in the outside one.
65 vs 64 Side
New in the 1965 Grand Prix was a partial covering of the rear wheel wells. Full-length molding was also added on the side panels.
65 vs 64 Rear
The rear fender lint on the 1965 Grand Prix was thinned and the taillights curved to the rear, integrated into the rear fender panel.
65 vs 64 Other
The 1965 Grand Prix featured a new automatic air conditioning option which allowed the driver to set a constant temperature. This system, first introduced by Cadillac in 1964, was available in addition to the regular Cir-L-Aire Conditioning. A front bench seat was also made available in 1965 for the first time. Also in 1965, the engine horsepower, wheelbase and weight all increased.
