 Full-sized cars and intermediates reverted from vertical to horizontal headlights while the sporty/performance 2+2 was dropped from the lineup.For 1969, Pontiac moved the Grand Prix from the full-sized lineup into a G-body model of its own based on the A-body intermediate four-door modified from 116 inches to 118 inches wheelbase chassis, but with distinctive styling and long hood/short deck proportions to create yet another niche product – the intermediate-sized personal-luxury car that offered the luxury and styling of the higher priced personal cars such as the Buick Riviera and Ford Thunderbird and the old Grand Prix and Olds Starfire but for a much lower price tag.Pete Estes, who like Knudsen had moved to be general manager of Chevrolet in 1966 and Delorean, general manager of the Pontiac division, needed a car to take the place of the sagging sales of the full size Grand Prix, but the development cost of the car was too much of burden for Pontiac division alone, so Delorean went to his old boss at Chevrolet to gather support for the development cost of the new "G" body Grand Prix.
