Grand Prix background and what was new in 1968
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 1968 Grand Prix in context
The 1968 Grand Prix was the 7th and last of the B-body based 1st Generation (1962-1968). 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.
68 vs 67 Front
The headlights were still hidden as in the 1967 Grand Prix but the front was significantly redesigned with small horizontal, egg crate cross hatching and the chrome beak extending up into the front of the hood. The “GP” logo still appeared on the driver side front grille.
68 vs 67 Side
The “wasp-waisted” rear panels and the full-length molding of the 1967 Grand Prix remained.
68 vs 67 Rear
The rear of the 1968 Grand Prix was significantly different from the 1967, with a down swept deck incorporating a sculpted “V” stylistically like that on the hood. The rear of the 1968 Grand Prix also featured sculpted molding instead of tailfins and L-shaped taillights that were integrated into and wrapped around the bumper.
68 vs 67 Other
The 1968 Grand Prix also featured a new interior and instrument panel design. The 400 cubic inch V8 350 horsepower standard engine (also standard in 67 and 69-70) was the biggest standard engine ever on a Grand Prix but competition and seven years without a major redesign took their toll and production slipped to the lowest level since 1962.
