Grand Prix background and what was new in 1974
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 1974 Grand Prix in context
The 1974 Grand Prix was the second of the A-body based 3rd generation (1973-1977). With the 3rd generation, the Grand Prix still continued its long hood/short deck design but introduced a fixed rear “opera” window and a concave top edge of the door panels.
74 vs 73 Front
In the 1974 Grand Prix, the front split grille sections were moved closer together and the vertical bars place entirely above the bumper. The headlight bezels were made taller and more vertically rectangular. The turn signals were still cut into the leading endge of the front fenders.
74 vs 73 Side
The side panels on the 1974 Grand Prix changed very little from the 1973.
74 vs 73 Rear
In the rear of the 1974 Grand Prix, the license plate and fuel filler were moved above the bumper and the taillights had a narrower center clear strip and were turned vertically, wrapping up onto the rear deck.
74 vs 73 Other
J (standard) and the sportier, more luxurious SJ styles were offered. With the 1973 OPEC oil embargo, fuel shortages and higher gas prices caused buyers to prefer smaller cars and Grand Prix sales suffered. Production dropped by 35%. Of the 99,817 produced, 13,841 were SJ. The 1974 model also included a federally mandated system that prevented ignition unless the front seat belts were fastened. Due to public backlash, the federal mandate was rescinded within the year.
