The grille was slightly revised and new taillights that featured 22 individual lenses were the new visual revisions for the 1973 Charger. Most noticeable, however, was the new roofline around the quarter windows.
For 1954, the Bel Air stayed essentially the same, except for a revised grille and taillight, and a revised engine that had insert bearings and higher oil pressure. The revised engine saw a slight performance increase.
The legendary 426 HEMI was no longer available for the 1972 Charger, and the top-of-the-line performance model R/T was eliminated. Because of economic crises, the Charger began to be marketed as more of a low-end luxury coupe with lower prices and waning power.
