- Quick Specs -

The 1970 Cutlass was available in seven body styles: the base F-85 two door sedan, as well as two door hardtops offered in both notchback Cutlass Supreme and fastback Cutlass S and 442 body styles - a practice similar to Ford and Mercury intermediates of that time, which were offered in both notchback and fastback coupes starting in 1968. Also available were a four door hardtop, four door sedan, a convertible and a flat top station wagon called the Custom Cruiser, as well as the fancier Vista Cruiser station wagon.

With GM tossing out the 400 cubic-inch limit for intermediates and the 4-4-2 now coming standard with the larger 455 cubic-inch Rocket V8 from the big Oldsmobiles and previously used in the 1968-69 Hurst/Olds, Olds discontinued the 400 engine entirely and also offered the 455 as an option in the Cutlass S models and the Vista Cruiser wagons. There was an SX option that became available in 1970 and was available only on the Cutlass Supreme hardtop and convertible. The SX cars all had the 455 engine and TH-400 automatic transmission.

The same assortment of three- and four-speed manual transmissions were carried over from previous years with Hurst shifters used on floor-mounted three-speeds and all four-speeds. The two-speed Jetaway automatic transmission was discontinued entirely with the three-speed Turbo Hydra-matic now the sole offering for shiftless driving. Cutlass S coupes with the optional Strato bucket seats and Turbo Hydra-matic could be equipped with the Hurst Dual-Gate shifter (also known as the "His and her-shifter") in conjunction with the extra-cost center console. The Hurst Dual-Gate made it possible to either put the transmission in Drive, and let the transmission decide when to shift. Or it could be placed in a manual mode, much like todays computer controlled automatics.
