Grand Prix background and what was new in 1970
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 1970 Grand Prix in context
The 1970 Grand Prix was the second of the “G-body” based 2nd Generation (1969-1972). 2nd Gen Grand Prix’s featured a Duesenberg inspired long hood/short deck design, marketed aggressively by Pontiac as the longest hood in the industry. Given the success of the 1969, very little was changed for 1970.
70 vs 69 Front
The sculpted V on the hood of the 1970 Grand Prix continued to be prominent and the front parking lights were still integrated into the front fender. One change was that the front grille got vertical slats.
70 vs 69 Side
In the 1970 Grand Prix, vertical hash marks were added on the front fenders just behind the wheel wells. The 1970 version also featured flush door handles.
70 vs 69 Rear
There was little change from 1969. Horizontal taillights were still integrated into the fender.
70 vs 69 Other
The 1970 Grand Prix continued to feature the 400 V8 350hp engine introduced in 1967 and the biggest standard engine ever offered on a Grand Prix. The 428 engine upgrades were dropped in favor of a 455, the largest engine ever offered on a Grand Prix. A special, semi-custom version with a Hurst shifter, the “Hurst SSJ” version was also introduced in 1970.
