The Most Important Grand Prix Pontiac Ever Built Wasn't the One You Think ! |1973 Pontiac Grand Prix

Everyone remembers the 1969 Pontiac Grand Prix as John DeLorean's masterpiece — the car with the six-foot hood that redefined American personal luxury. But the most important Grand Prix Pontiac ever built was not the one you think. In this video, we tell the full story of the 1973 Pontiac Grand Prix: the car that arrived under impossible conditions, shattered every sales record the nameplate had ever set, and quietly saved the Grand Prix legacy when everything in the industry was conspiring to end it. We cover the complete history of the Grand Prix from its 1962 origins through DeLorean's revolutionary 1969 redesign, then trace the forces that made a total reinvention necessary for 1973 — federal safety regulations, tightening emissions standards, and the end of the muscle car era. We break down the new Colonnade architecture, the styling decisions that kept the Grand Prix's identity intact on a shorter platform, the 400 and 455 cubic inch V8 engine lineup, the story of the Super Duty 455 that was originally planned for this car, the SJ performance package with its Radial Tuned Suspension, and the record-breaking production total of over 153,000 units that justified everything that followed through the rest of the decade. If you think the 1969 is the only Grand Prix worth talking about, this video will change your mind. Topics covered in this video include the history of the Pontiac Grand Prix, the 1973 GM Colonnade redesign, the Pontiac 455 V8 engine, the Grand Prix SJ package, personal luxury coupes of the 1970s, John DeLorean and Pontiac history, classic American muscle and luxury cars, and the 1973 Arab oil embargo's impact on the American auto industry.
