The Chevrolet Chevelle is a medium-sized automobile that was produced by Chevrolet in three generations for the years 1964 to 1978. Part of the General Motors (GM) A-Body platform, the Chevelle was one of Chevrolet’s most successful brands. Body styles including coupes, sedans, convertibles and station wagons. The Super Sport versions were produced during the 1973 model year, and Lagunas from 1973 to 1976. After an absence of three years, El Camino was reintroduced as part of the new Chevelle line. The Chevelle also provided the platform for the Monte Carlo introduced in 1970. The Malibu, the top-of-the-line model until 1972, completely replaced the Chevelle brand for the redesigned and reduced 1978 model.
Third generation (1973–1977):
The most extensive redesign in its 10-year history marked the 1973 Chevelle. Due to concern over proposed Federal rollover standards, convertible and 4-door hardtop models were discontinued, while the 2-door hardtop was replaced by a pillared coupe—named “Colonnade Hardtop”. This body style featured a semi-fastback roofline, frameless door glass and fixed, styled “B” pillars, structurally strong enough to contribute to occupant safety of a roll-over type accident. This move was somewhat controversial with the buying public as hardtops had been a staple of American cars for over 20 years and their presence almost taken for granted. Once the initial surprise was overcome however, the Colonnade models became a huge sales success. The Monte Carlo coupe was the biggest seller of the Chevrolet A-body line (actually designated A-Special), although the bread-and-butter coupes, sedans and station wagons also sold well. Distinctive rear quarter glass on 2-door coupes and new side windows with styled center pillars were featured on 4-door models. Rear windows on coupes no longer opened. In addition to the new roofline, front and rear ends looked markedly different this year as 1973 was the year of the federally mandated 5 mph (8.0 km/h) front bumper, adding to the car’s length. Additional new body features were an acoustical double-panel roof, tighter-fitting glass and flush style outside door handles. Wheelbase dimensions were retained; a sporty 112 inches (2,800 mm) for coupes and 116 inches (2,900 mm) for sedans and station wagons, but bodies were five inches (127 mm) longer and an inch wider with a 1-inch (25 mm) wider wheel track. The station wagon, available in 6 or 9 passenger seating, featured a new counterbalanced liftgate which allowed for easier entry and loading up to 85 cubic feet.
Plans to release the updated A-body lineup was scheduled for the 1972 model year but a strike which occurred at some GM assembly plants delayed the release for a full model year, eventually extending the lifecycle of the 1968-era generation; the redesigned A-bodies were designed in studio where it had more of a European influence – at the time of development John Z. DeLorean was the chairman at the Chevrolet division where he delayed some product releases and extending the lifecycle of some of its products; the redesigned A-bodies had some styling cues lifted from the concurrent second generation F-bodies – the front suspension was integrated into the A-body redesign with output from respective GM divisions (each division had its own sheetmetal design).
1973 models also introduced molded full foam front and rear seat construction, a flow-through power ventilation system, an inside hood release, a larger 22 gallon fuel tank, and “flush and dry” rocker panels introduced first on the redesigned 1971 full-size Chevrolets. Another structural improvement was side-impact guard beams in the doors, as required by new Federal Motor Vehicle Safety Standards. New options included swivel bucket seats with console for coupes and Turbine I steel-backed urethane wheels. A power moonroof was an option in 1973-75. Interior roominess of the ’73 Chevelle was improved, particularly in the rear. Headroom was up slightly and shoulder room gains were by 1.6 inches (41 mm). Rear seat legroom was up 3.5 inches (89 mm) in sedans. Another was a 15.3-cubic-foot (430 L) luggage capacity, an increase of 2.5 cubic feet (71 L) over 1972 models. Still another benefit of the new body designs was greatly improved visibility, up 25% in coupes and wagons, and 35% in sedans. The unusually thin windshield pillars also contributed to much better visibility.
The chassis design was new , with a sturdier perimeter frame, revised chassis/body mounts, larger 8½ inch rear axle, wider 6-inch wheel rim width, revised rear control arm bushings, increased front and rear suspension travel, adjusted shock absorber location, and revised front suspension geometry- The left wheel was adjusted to have slightly more positive camber than the right which resulted in a more uniform and stable steering feel on high-crown road surfaces while maintaining freeway stability. Clearances for spring travel were also revised; the coil springs at each wheel were computer-selected to match the individual car’s weight. Front disc brakes were now standard on all ’73 Chevelles. John Z. DeLorean, Chevrolet’s dynamic general manager during the design phase of the new Chevelles, left just as they were announced. He departed in late September 1972 to start a brief period as vice president of General Motors’s Car and Truck Group. Critics compared the GM Colonnade line favorably to Ford and Chrysler intermediates.
