The third-generation Pontiac Grand Prix, introduced for the 1973 model year, was built upon GM's redesigned intermediate A-body platform. Reacting to stringent federal safety and bumper standards, the vehicle grew larger and heavier, incorporating prominent 5-mph bumpers and fixed rear quarter windows while retaining its trademark formal roofline and long hood proportions. Engine options transitioned through various V8 configurations, peaking with massive 7.5-liter powerplants designed to maintain adequate performance despite tightening emissions regulations. Inside, the cabin focused heavily on plush luxury, offering velour or leather bench and bucket seating options, wood-grain dashboard accents, and comprehensive instrumentation. Throughout its lifecycle, the model underwent sequential aesthetic facelifts involving revised grille inserts, rectangular quad headlights, and updated taillight treatments. Primarily marketed across North America, this generation successfully navigated the shifting automotive landscape of the mid-1970s by prioritizing plush ride quality and distinctive styling.
