This post is about the 1970-1972 Oldsmobile Cutlass Supreme. For an overview of the Cutlass line, see our post on the Oldsmobile Cutlass.
I have a special place for this model of the Cutlass Supreme. My oldest sister had one of these as her first car. I was only 8 years old at the time, but according to my parents I started becoming a motorhead at 6 months old. I just thought this was the coolest car ever. Even now, some 30 plus years later, I still think this model of the Cutlass Supreme is the coolest car ever. The flowing lines and proportions are just right.
In 1969, the Cutlass Supreme was the top line model of the A-bodied Cutlass series and shared the same body as the regular Cutlass. For 1970 Oldsmobile gave Cutlass Supreme it’s own design, a hartdtop with a notchback roofline. This served as Oldsmobile’s entry into the burgeoning personal luxury market. The Cutlass Supreme would carry on in this role for its production run. Although the Supreme had its own roofline, it shared the front and rear body parts with the standard Cutlass line. In addition to the two-door hardtop (Holiday Coupe), for 1970 the Cutlass Supreme also offered a four-door hardtop (Holiday Sedan) and a convertible bodystyle.
To support its position in the personal luxury market, the Cutlass Supreme interiors were more luxurious that those of the standard Cutlass. The Supreme, had a choice of a custom sport notchback bench seat with armrest in Osborne cloth or Moroccan vinyl. A no cost option extra cost on coupes and convertibles were Strato bucket seats in Moroccan vinyl. With the bucket seat option, the Supreme could be ordered with a center console with floor-mounted shifter. The Supreme with the Turbo Hydra-Matic transmission could also be had with the Hurst Dual-Gate shifter commonly found on the Oldsmobile 442.
The1970 Cutlass Supreme coupe and convertible could be ordered with the Code Y-79 high performance “SX” option package. The SX package included several versions of the larger 455 cubic-inch Rocket V8 from the Oldsmobile 442. The SX also used the cutout rear bumper, exhaust trumpets and rallye suspension. The SX also came with distinctive SX badges.
Changes to the Supreme were minimal in 1971 and 1972. However in 1972 the hardtop could be equipped with the L75 455 and M20 four speed transmission. It is estimated that only 77 such cars were made. The L75 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.
Also available in 1972, was a Hurst/Olds was based on the Supreme two-door hardtop and convertible, powered by both versions of the 455 Rocket offered with a Turbo 400 transmission with Hurst Dual/Gate shifter. The H/O convertible also served as the Indianapolis 500 Pace Car in 1972.
For 1973, the Cutlass Supreme and the standard Cutlass were moved to the new Colonnade A-body platform shared with the Chevrolet Malibu, Pontiac LeMans, and Buick Century/Regal. Something of beauty became common.
