Cutlass Supreme The Oldsmobile Cutlass Supreme was a mid-size car produced by General Motors for the American market. It was always at the top of the Cutlass range. It began as a trim package, developed its own roofline, and eventually was mechanically divorced from the later, smaller Cutlasses.
The Cutlass Supreme name lasted from 1966 until 1997. There was no direct replacement for the Cutlass Supreme itself, although the Intrigue introduced for 1998 was designed in size and price to replace all the Cutlass models.
First Generation
The name first appeared in 1966, the first year of GM's new intermediate two-door hardtop. The Cutlass Supreme was Oldsmobile's version of this bodystyle. It continued so for three years.
Second Generation
In 1970, a change was made. The Cutlass Supreme name was switched to Oldsmobile's equivalent of the downsized Pontiac Grand Prix on the GM A platform, to give the division an entry in the burgeoning market for smaller personal luxury cars. As such, it had a new notchback roofline, while lower trim-line Cutlass coupes had a near-fastback roof. The model remained in this role for virtually all of its production life. Unlike the Grand Prix and the also-related Chevrolet Monte Carlo, which had wholly separate bodies and names from their less expensive siblings, the Supreme used front and rear body parts from the standard Cutlass line and was always marketed as part of it.
Supreme interiors were more luxurious that those of other Cutlass models, with a choice of a Custom Sport notchback bench seat with armrest in Osborne cloth or Moroceen vinyl or, at no extra cost, Strato bucket seats in Moroccen vinyl. Available at extra cost with the bucket seats was a center console with floor-mounted shifter for which the Turbo Hydra-Matic transmission could also be had with the Hurst Dual-Gate shifter commonly found in the division's musclecar, the Oldsmobile 442.
For 1970 and 1971, both the Cutlass Supreme coupe and convertible were available with the Code Y-79 high performance "SX" option package. The "SX" option included several versions of the larger 455 cubic-inch Rocket V8 borrowed from the Olds 442 along with the cutout rear bumper and exhaust trumpets, 442's rallye suspension (optional), distinctive SX badges and other features.
A W31 option added body color bumpers and a rear spoiler, distinctive stripes and badging, and a hotter camshaft with increased lift and duration for the 350 engine.
1972 was the only year in which the Cutlass Supreme notchback hardtop could be equipped with the L75 455 and M20 four speed transmission, and only 77 of these cars were produced. All 1972 L75 455/M20 cars used the larger 2.07 valves and the W30 automatic camshaft. This gave the L75 455/M20 cars 270 net horsepower, as opposed to the TH400 automatic-equipped L75 cars, which produced 250 net horsepower.
Third Generation
In 1973, the Cutlass Supreme, like other GM mid-size cars, was redesigned. Hardtop models were replaced by new "Colonnade" styling with fixed center pillars. Concerns over proposed rollover standards caused many automakers to phase out their pillarless hardtops throughout the 1970s (this included Ford's Torino coupe) and convertibles, and the Cutlass was no exception. Cutlass Supreme coupes had a unique roofline not shared with other Cutlass coupes, as well as unique front end styling. For 1976, a new front fascia design with quad rectangular headlamps debuted. This new Cutlass design was highly successful, becoming one of the best-sellers of the time. The Cutlass line as a whole was America's best-selling car in 1976. By 1977, however, GM had downsized its full-size models, and the Cutlass Supreme was now nearly identical in size to the redesigned Delta 88. That situation would last only that one year, as GM planned to downsize the Olds Cutlass and other intermediates for 1978.
In addition to the Colonnade hardtop coupe, the Cutlass Supreme was also offered in a four-door Colonnade sedan (with six-window styling and frameless door windows) as well as six-and-nine passenger station wagons - the wagons with the woodgrain exterior trim were marketed under the Vista Cruiser nameplate previously used on Oldsmobile's stretched-wheebase station wagons with raised roof and skylights from 1964 to 1972.
The Supreme Colonnade sedan was available in 1973 as the Cutlass Salon, which was an option package that included radial tires, upgraded suspension and reclining bucket seats upholstered in cordoroy trim along with color-keyed wheelcovers - designed as sort of a European-style luxury/touring sedan similar to the Pontiac Grand Am of the same period. For 1974, the Salon package was also made available on the Supreme Colonnade coupe and in 1975, the Salon was upgraded to a separate series available in both sedan and coupe.
For 1976, the Cutlass Supreme Brougham coupe was added to the line, featuring a more luxurious interior trim than the regular Supreme model with pillowed crushed velour upholstery and 60/40 bench seats similar to the larger Ninety-Eight Regency. For 1977, the Brougham was also available as a four-door Colonnade sedan.
