1971 Oldsmobile Cutlass Supreme SX

The full name “Oldsmobile” was first used in 1900. Prior to that, the automobiles were known simply as “Olds”, built by the Olds Motor Works of Lansing.

There are those who claim that it was Oldsmobile that created the first muscle car when it stuffed its hot new fullsize Rocket V8 into its midsize model to create the Olds 88 and Super 88 series back in 1949. But it wasn’t until 1964 that Oldsmobile would return to the concept, encouraged by the success of the Pontiac GTO.

For 1970, option code W-32 created one of the all-time great street-sleepers of the muscle car era. Basically, this code resulted in the 442 drivetrain, which included the 365-horsepower 455 and dual exhausts, stuffed into the new-for-’70 “formal roof” Cutlass Supreme body style. A Turbo 400 automatic was the only trans offered. With Cutlass Supreme styling and the understated SX ornamentation wrapped around a 442 heart, the SX had to be Olds’ ultimate Q-ship. By the way, the SX package became option code Y-79 in 1971, the only other year it was offered.
