base Cutlass coupe, while Cutlass S included full carpeting on floor and lower door panels, woodgrain trim, deluxe steering wheel and more luxurious cloth-and-vinyl or all-vinyl bench seat, or optional swiveling Strato bucket seats with vinyl trim that could be rotated 90 degrees for easy exit/entry. Center console with floor shifter was optional with either the 4-speed manual or Turbo Hydra-matic transmissions. 1974 The 1974 4-4-2 received the same facelift as other Cutlasses that year including a revised grille and new flush taillights over a newly mandated rear bumper to match the similarly mandated front bumper introduced in '73. It remained a handling and appearance package available on both base Cutlass and Cutlass S Colonnade coupes. Engine offerings included the standard Rocket 350 four-barrel V8 or optional Rocket 455, which reintroduced the W-30 code that signified the top 4-4-2 engine option package from 1966 to 1972. Power steering and Turbo Hydra-matic transmission became standard equipment on 4-4-2 and all other Cutlass models. The four-speed manual transmission with Hurst shifter was dropped from the option list. GM-specification radial tires were introduced as an option.

It was once again a handling/appearance package on base Cutlass and Cutlass S coupes with content similar to previous years. Radial tires became standard equipment, along with a GM High Energy electronic ignition. All engines were mated to catalytic converters, which required use of unleaded gasoline and spelled the end of true dual exhausts. With economy now a selling point following the 1973–74 energy crisis, the 1975 4-4-2 and most other Cutlass models no longer included a V8 engine as standard equipment. For the first time since its 1964 introduction, the 4-4-2 came standard with a six-cylinder engine, Chevrolet's 250 cubic-inch inline unit which had previously been offered on some Oldsmobile intermediates from 1966 to 1971 and the compact Omega since its 1973 introduction. Also new was a small Oldsmobile-built 260 cubic-inch Rocket V8 specifically designed for fuel economy. The 170-horsepower 350 Rocket V8 was now an extra-cost option along with the 190-horsepower 455 V8. A three-speed manual transmission was reinstated as standard equipment with the six-cylinder engine, with
