context_page_description: The Oldsmobile Cutlass was a range of automobiles produced by General Motors' Oldsmobile division between 1961 and 1999. At its introduction, the Cutlass was Oldsmobile's smallest model; it began as a unibody compact car, but saw its greatest success as a body-on-frame intermediate.
  Introduced as the top trim level in Oldsmobile's compact F-85 line, the Cutlass evolved into a distinct series of its own, spawning numerous variants, including the formidable 4-4-2 muscle car in 1964, premium Cutlass Supreme in 1966, and outright performance Hurst/Olds in 1968, as well as the Vista Cruiser station wagon.
  By the 1980s, Oldsmobile was using the Cutlass as a sub-marque, with numerous vehicle lines bearing the name simultaneously. These included the Cutlass Calais compact, the midsize Cutlass Ciera, the Cutlass Cruiser station wagon, and top of the line midsize Cutlass Supreme.
  The Cutlass was named after the type of sword, which was common during the Age of Sail.
context_section_description: The 1970 F-85 and Cutlass was available in seven body styles, three of which were coupes: a pillared fastback Sports Coupe (in F-85, Cutlass S or 4-4-2 trims), an hardtop fastback Holiday Coupe (Cutlass S and 4-4-2 only), and finally a more formal notchback Holiday Coupe, only offered in Cutlass Supreme trim. This practice was similar to that followed at the time by Ford and Mercury for theirintermediates, which were offered in both notchback and fastback coupes starting in 1968. Also available were a four-door hardtop Holiday Sedan, a four-door Town Sedan, a convertible, a flat-top station wagon called the Custom Cruiser, as well as the fancier Vista-Cruiser station wagon. Counting all trim level and body style permutations, Oldsmobile's 1970 lineup included 15 different intermediate models.
  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 today's computer-controlled automatics.
  A 1970-only offering was the Oldsmobile Rallye 350, a value-priced high-performance model using the 350 engine. It was intended for younger buyers that wanted the performance and looks of a supercar, but might have trouble with the rising insurance premiums associated with 455-engined cars like the 4-4-2. In essence the Rallye 350 was an appearance package (coded W45) tied to mandatory options, and could be ordered on the Cutlass S Holiday or Sports Coupe as well as on the F-85 Sports Coupe. All Rallye 350s were painted in Sebring Yellow with matching urethane-coated bumpers front and rear. The package also included special black and orange decals, blacked out grille and yellow-painted 7" wide Super Stock II rally wheels without trim rings, wearing G70×14" bias-belted Wide Oval blackwall tires. The engine was the L74 air-inducted high-compression 350 cu.in. Rocket V8 engine, fitted with a Quadrajet carburetor and producing 310 hp (230 kW). Required options were the associated "Force-Air" fiberglass vented hood, dual exhaust with 4-4-2-style megaphone outlets, 3.23:1 axle ratio, heavy-duty "Rallye-Sport Suspension" with front and rear stabilizers, sports mirrors and sports steering wheel.
