The 1973 Chevrolet Chevelle series had attributes of General Motors’ new mid-size car “Colonnade” design. It was the third generation of Chevelle models, and after three years with slight modifications to any model, the whole line experienced the most far-reaching restyling in its 10-year reign in 1973 to help boost sales.

This model had a semi-fastback roofline that had vaulted door frames and a bulky rear-quarter window, the Chevrolet Chevelle 1973 models looked significantly unlike its previous versions, and the long-standing pillarless hardtop coupe body style was discarded.
The new top-of-the-line Laguna coupes and sedans were joined to the Malibu versions and boosted Chevelle sales. The lagunas had a skin-colored urethane plastic front end boasting a chrome-plated cast grille housing round indicator lights.
The Laguna model was manufactured in two varying station wagon versions, the base model and a Laguna Estate model.
A Super Sport (SS) coupe version remained obtainable, but convertibles were stopped from the Chevelle line. Prospective buyers could order a 1973 SS station wagon – optioned with a 454-cubic-inch V-8 engine, although this mix of sport and down-to-earth wagon qualities would last only for one season.
The Chevelles sold like wild fire: a total of 327,631 were sold for the 1973 model year, an additional 59,108 station wagons. The Malibu versions of the Chevelle persisted in selling by an extensive margin, but the more expensive Laguna coupe and sedan also made decent sales, with 56,036 being snapped up by customers.
Super Sport was obtainable on 28,647 Chevelles, of which 2,500 were powered by the big 454-cubic-inch engine — the last of their type, as it was its final year in production.

The Chevrolet Chevelle 1973 wheelbases were retained at 112 inches for the 2-door models and 116 inches for the 4-doors. But the bodies were an inch wider and five inches more in length. Furthermore, it also possessed new roofline, front and rear ends, which looked noticeably unlike previous years. Every 1973 Chevrolet Chevelle were fitted with frameless door glass, front disc brakes, and fixed, style “B” pillars.
The front suspension significantly improved handling and was replicated from the Camaro/Firebird design. The Chevrolet Chevelle 1973 engine selections ranged from the 250 six to the 454 V8 engine. These engines were dependable for several miles owing to the toughened engine valve seats and hydraulic camshafts and also permitted them to run on the progressively more popular unleaded standard gasoline.

1973 Chevrolet Chevelle SS
The Chevrolet Chevelle 1973 SS option was obtainable for its last year, before being written off at the end of the year model. Adopting either, the 350- or 454- cubic-inch motor, the SS option was obtainable in an extensive range of Chevelle models, as well as some station wagons. Although the power was quite the same from the preceding two years, cost-effective unease and the looming gas shortage caused an untimely end of the SS, and of the Chevelle as a muscle car model.
Also, the major SS engine was a 454-cubic-inch V-8, giving 245 horsepower. Standard Chevelles had a standard 250-cubic-inch six or 115-HP 307-cubic-inch V-8, but the Laguna was fitted with a 145-HP350-cubic-inch engine having a 2-barrel carburetor. That engine and a 175-HP step-up version were also available in other 1973 SS Chevelle models.
There are very few original 1973 Chevrolet Chevelle left in their original state and most of them belong to private collectors or in car showrooms.
