1966 Oldsmobile Cutlass
General Motors’ push to get into the compact market was spearheaded by Chevrolet with the Corvair Z-body in 1960. In 1961, Oldsmobile got their own compact with the Y-body, which shared similar tooling to the Z-body. Olds shared the Y-body with both Pontiac (Tempest, LeMans) and Buick (Special, Skylark), with some major differences. While the Corvair was a rear-engine platform, and the Pontiac Tempest was a front engine/rear transaxle configuration with a rubber composite driveshaft, the Oldsmobile Cutlass was a conventional layout with a V8 engine up front and live axle rear end. For 1961 there were only two models, a 4-door sedan and station wagon. Late in the model year a 2-door sedan and 2-door coupe were added to the Cutlass line. Then in 1962 a 2-door hardtop and convertible joined the line. Moderately restyled for 1963, an all-new Cutlass based on the GM 115-inch wheelbase intermediate A-body platform was the big news for 1964. While the first gen Cutlass was unibody construction, the 1964 had a separate frame. The “442” high performance version of the Cutlass also debuted this year in response to Pontiac’s GTO. The numbers stood for “4-barrel carburetor/4-speed transmission/dual (2) exhaust.”
Modest Cutlass facelifts marked the remainder of the 2nd gen’s life, before the all-new corporate A-body platform was released in 1968. Larger engines and a general performance image were pushed by Olds, while still maintaining the high style luxury of the standard Cutlass line. The Hurst/Olds (H/O) 442 performance package was also introduced this year.
For 1973 a new larger, corporate A-body eliminated hardtops in anticipation of federal roll-over safety mandates. The new “Colonnade” body featured a semi-fastback top that rolled into a sloping trunk. Federally mandated five-mph front bumpers looked a bit like afterthoughts as GM struggled to keep up with the fast moving government requirements. Only three bodies were available, a 4-door sedan, 2-door coupe, and station wagon. The Colonnade bodies ran from 1973-1977. It was also during this period that as the muscle car market shriveled, Olds cranked up the Cutlass’ luxury features, which saw production numbers continue to climb. In 1976 it was the bestselling car in America, outselling the bread-and-butter Chevrolet. It would continue this distinction into the 1980s
A major downsize occurred for 1978 on all GM A-bodies which besides the Cutlass included the Chevy Malibu, Buick Century and Regal, and Pontiac LeMans. Besides the more traditional three-box sedans, a “Salon” fastback 2- and 4-door sedan were offered exclusively to both Olds and sister division Buick. Both body styles were sales disasters. The 4-door Salon was dropped after 1979 and the 2-door Salon met the same fate in 1980. By 1982 the Cutlass line became an umbrella for a series of distinctly different lines. A Cutlass Ciera, Cutlass Supreme, and Cutlass Calais were all marketed as distinctly different coupes and sedans in a confusing array of different front-wheel and rear-wheel drive platforms. The Ciera ran from 1982-1996, the Cutlass Supreme A-body from 1980-1988, and front-wheel drive replacement from 1988-1997, and the Cutlass Calais from 1985-1991
1966 F-85 Cutlass
The Cutlass received a major facelift with smoother features and extended sail panels for the top. It also received the accented full-round wheel openings that would distinguish most Oldsmobile products for years to come. A special late year option was the “W-30” fresh air option—the hottest 442, with a special 390hp tri-carb induction available only this one year. Featuring three Rochester 2bbl carbs in a row, it produced 360hp at 400lb-ft of torque. 54 were built for the NHRA’s 50-minimum homologation rule. W-30 would continue to mean top performance for years to come in the Olds portfolio of performance.
