1963 Pontiac Grand Prix
The Grand Prix line started as a performance package for the Catalina coupe, which rode on the full-size B-body GM platform. It was distinguished by a unique grille and taillights, bucket seats, center console transmission shifter, and more. John De Loren was head of Pontiac’s Advanced Engineering, and tried to infuse performance into the entire Pontiac line. To that end he even OK’d the “Super Duty” 421ci performance package into a few Grand Prix’s for racing purposes. The clean 1963-1964 models featured smooth, unique hardtops that featured curved rear windows, and expanded on their performance engine options while adhering to luxury offerings for the interior. 1965-66 models continued with GM’s all-new boxed-perimeter B-body frame and shared sheetmetal, as well as continuing the unique stacked headlights, split grille, and performance/luxury image. 1967 saw the addition of the one-year-only Grand Prix convertible, and featured revised sheetmetal featuring hidden headlights with vents in the leading edges of the fenders for parking lights. 1968 saw a more baroque body restyle with a wide grille continuing with hidden headlights and a more formal top. 1969 was the introduction of the new corporate “G-body” which featured dramatically longer front ends ahead of the cowl. The new Grand Prix would have this exclusively for a single year before sharing it with the Chevy Monte Carlo. With a unique upright grille and headlights surrounded by body-color sheetmetal, it made for a dramatic personal luxury car, and sales shot up to over 112,000 units. Though sales slipped in 1970 and 1971, they rose past 90,000 cars in this version’s last year of production in 1972. For 1973 the third-gen based on the new “Colonnade” coupe abandoned the hardtop styling Grand Prix’s were known for to instead embrace the new coupe body adapted for pending federal roll-over safety standards. In spite of competition within Pontiac like the Grand Am, and outside with the Monte Carlo, Grand Prix sales were over 150,000 in 1973. Corporate Average Fuel Economy standards and safety regulations were changing the automotive environment, and the Grand Prix saw horsepower decrease. With GM corporate downsizing in the late-1970s, the Grand Prix followed by adopting the new 108-inch wheelbase A-body. Much more conservative with less sculpturing than the previous A-body, nevertheless sales ratcheted up to over 228,000 GP’s sold, and ended 1979 with a similar production of over 210,000 units sold.
1963 Grand Prix
While Grand Prix’s featured the same new body as other full-size Pontiacs, it got the unique top that eliminated the faux-folds of a convertible for a top with an inward curving rear window. Gone was the body sculpturing, and instead a clean body even eliminating trim presented a much more sophisticated car. A full-width grille in the rear incorporated taillights inside of the fine grille that effectively hid them, for a very sleek, clean look. Two “High Output” (HO) 421ci engines replaced the previous year’s Super Duty. A wide range of options were available, including cruise control and tilt steering for the first time.
