Chevrolet Chevelle History, 1964–1977: All Three Generations
On this page
The Chevrolet Chevelle had a fourteen-year run, from the 1964 model year through 1977. In that time it was a family sedan, a station wagon, a pickup (as the El Camino), a personal luxury coupe and, most famously, one of the defining muscle cars of the era. This overview walks through the three generations and the market forces that shaped each one.
Why Chevrolet needed a midsize car
By the early 1960s Chevrolet sold the full-size Impala and Bel Air line, the compact rear-engine Corvair and the conventional compact Chevy II. There was a gap in between. Ford had moved into it with the Fairlane for 1962, and buyers wanted something roomier than a compact but easier to park and cheaper to run than a full-size car.
General Motors answered with a new shared intermediate platform for 1964, the A-body. Every GM car division got a version: Pontiac Tempest and LeMans, Oldsmobile F-85 and Cutlass, Buick Special and Skylark, and the Chevrolet Chevelle. The Chevelle used body-on-frame construction with a perimeter frame, coil springs at all four corners, and a 115-inch wheelbase in its first generation.
First generation: 1964–1967
The 1964 Chevelle arrived with a wide spread of body styles: two- and four-door sedans, a two-door hardtop (Chevrolet called it a sport coupe), a convertible, station wagons, and the El Camino car-pickup, which returned for 1964 on the Chevelle platform. Trim levels started with the Chevelle 300 and ran up to the Malibu, which was the upscale series. The Malibu SS (Super Sport) was offered on the sport coupe and convertible and was mostly an appearance and comfort package: bucket seats, console, special trim. It could be ordered with a six or a V8.
Power at launch came from inline sixes and the 283 small-block V8, with the 327 added during the 1964 model year. Chevrolet initially kept big engines out of its intermediate, but the success of the Pontiac GTO, introduced as a LeMans option in 1964, changed the calculation quickly.
The turning point was the 1965 Z16. It was a special-order Malibu SS 396 with a 375 hp version of the new 396 cubic-inch "Mark IV" big block, a boxed frame, heavier-duty suspension and brakes, and unique trim. Only about 200 were built, most of them hardtops, and they were largely placed with influential customers and dealers. The Z16 proved the concept.
For 1966 Chevrolet restyled the Chevelle with more rounded, "Coke bottle" lines and made the SS 396 its own series. From 1966 through 1969 the SS badge on a Chevelle meant a 396 big block was under the hood. The 1967 update brought refinements, including optional front disc brakes.

Second generation: 1968–1972
The 1968 redesign gave the Chevelle the long-hood, short-deck proportions most people picture today. GM split the A-body wheelbase: two-door models rode on 112 inches, while four-door sedans, wagons and the El Camino used 116 inches. The sport coupe gained a semi-fastback roofline.
In 1969 the SS 396 changed from a separate series to an option package that could be added to certain Chevelle and Malibu models. That detail matters to buyers and collectors, because it affects how a genuine SS is identified. Our guide on how to identify a real Chevelle SS explains why.
1970 was the peak. GM lifted its internal rule that had limited intermediates to 400 cubic inches, and Chevrolet responded with the SS 454. The LS5 version was rated at 360 hp and the LS6 at 450 hp gross, the highest factory rating of the classic muscle car era. The 396 was enlarged to 402 cubic inches that year but kept its 396 badges. The 1970 body was squarer and more muscular, with an available cowl induction hood.
The climate changed fast. Insurance surcharges on high-performance cars, rising fuel prices and coming emissions rules all pushed in one direction. For 1971 GM lowered compression ratios across its engines so they could run on lower-octane, low-lead fuel, and Chevrolet began publishing net horsepower figures alongside the traditional gross numbers. The LS6 was dropped from the Chevelle, though the LS5 454 stayed. The SS package could now also be ordered with a 350 small block, so for 1971–72 the SS badge no longer implied a big block. By 1972 Chevrolet quoted net ratings only, which made the engines look dramatically weaker on paper even where the hardware changed little.
Third generation: 1973–1977
The 1973 A-bodies were all new and became known as the Colonnade cars, after their thick, pillared rooflines. True pillarless hardtops and convertibles were gone, in part because of expected federal rollover standards that never fully arrived. The Colonnade coupes used frameless door glass with fixed rear side windows, and all models had to meet new 5 mph bumper rules.
The SS package continued for 1973, its final year on the Chevelle in this era. The new top model was the Laguna, with a body-colored urethane front end, followed by the aerodynamic Laguna Type S-3 coupe in the middle of the decade, a car that saw use in NASCAR. Malibu and Malibu Classic trims carried the volume. Engines ranged from inline sixes through small blocks to the 454 in the early Colonnade years, all with emissions equipment and modest net ratings.
The 1977 model year was the last for the Chevelle name. For 1978 GM downsized its intermediates, and Chevrolet's new smaller car was sold simply as the Malibu.

The Chevelle in the market
The Chevelle sold in large numbers throughout its life. Most were not muscle cars: they were six-cylinder and small-block sedans, coupes and wagons that served as everyday family transportation. That is worth remembering when shopping today, because the high production of ordinary cars is exactly what makes it easy to build a convincing SS tribute from a base car.
Its rivals changed over time. In the muscle market it competed with its own corporate cousins, the GTO, Olds 442 and Buick Gran Sport, plus the Ford Torino and Fairlane, Mercury Cyclone, Plymouth Road Runner and GTX, and Dodge Coronet and Super Bee. In the family market it competed with every intermediate on sale. Chevrolet's strength was choice: the Chevelle could be configured as anything from a stripped six-cylinder sedan to a 450 hp drag-strip car.
The Chevelle today
Today the 1966–1972 cars are the most sought after, especially SS models with documentation, and the 1970 SS 454 sits at the top of the market. First-generation cars have a loyal following for their clean styling, and Colonnade cars remain the affordable entry point, with excellent parts availability shared across the GM intermediate line.
