sport coupe disappeared for the first time since 1964, only to return in 1972. 1971 Model Year Appearance changes included a black grille with silver surround, silver headlight bezels, round parking lights in front bumper, and horizontal tail lights. Quarter mile performance as reported by Road Test magazine was 15.2 seconds at , and 0–60 mph in 8.9 seconds, using the TH400 automatic transmission. 1972 By 1972, the muscle car era was unmistakably in decline due to the twin blows of rising insurance rates and increasingly stringent Federal emissions standards. The 4-4-2 name reverted to an appearance and handling option package (option code W-29) in 1972 on the Cutlass Holiday coupe, Cutlass S sport coupe and Holiday coupe, and Cutlass Supreme convertible. The W-29 option was not available on Cutlass Supreme notchback hardtops. The 4-4-2 option package, which carried a modest sticker price of $29, consisted of the "FE2" suspension upgrades (heavy duty springs & shocks, front and rear sway bars, boxed lower rear control arms, and 14- by 7-in [356- by 178-mm] wheels), side striping, fender and decklid badging, faux hood louvers, and a unique grille. The rear bumper sported cutouts for exhaust tips, but only when paired with the optional L75 455 CID V8 in place of the standard Oldsmobile 350 V8. Interior trims differed on each 4-4-2 bodystyle, much like the early 1964–66 models. For the base Cutlass hardtop coupe a basic two-spoke steering wheel, vinyl or cloth/vinyl bench seat, and rubber floor mats were standard along; Cutlass S sport coupe and Holiday hardtop coupe featured full carpeting, deluxe steering wheel, courtesy lighting, and bench seats with cloth-and-vinyl or all-vinyl upholstery or optional Strato bucket seats; and the Cutlass Supreme convertible came with more woodgrain interior accents than the "S", along with an all-vinyl notchback bench seat with armrest or no-cost Strato bucket seats; a center console was optional. An AM/FM stereo radio with a tape player was $363. 4-4-2s could still be ordered with the additional W30' option, which included the still-potent L77 455 engine, rated at and s of torque with standard low-restriction dual exhausts. Other notable components of the W30 package included a lightweight aluminum intake manifold, the W25 fiberglass ram-air hood, anti-spin differential with 3.42:1 gears (3.73:1 available), and heavy duty cooling. Due to the low-vacuum at idle, air conditioning was not available, and power brakes were only available with an automatic transmission.
