1991 Oldsmobile Quad 442: The Last Year

This record's own title names the car the "1991 Oldsmobile Cutlass Calais Quad 442," and its own dek states that the front-drive Cutlass Calais Quad 442 used the 2.3-liter Quad 4 four-cylinder. This record's own overview states that a tertiary account describes the 1990-1991 4-4-2 as W-40 and W-41 options on the front-wheel-drive Cutlass Calais, powered by the 2.3-liter Quad 4 four-cylinder at 180 hp for the W-40 and 190 hp for the W-41.¹

This record's own key facts state that no production figure from a citable source was found, with uncited tertiary figures held as leads, and that Oldsmobile's 1991 catalogue describes the Cutlass Calais Quad 442 as a sport coupe with the 180-horsepower, 16-valve High-Output Quad 4 and a sport-ratio five-speed manual, 15-inch wheels having replaced 14-inch wheels in the package from November 1990. They also state that Ate Up With Motor says the Quad 442 sold poorly and was dropped after 1991.²

This record's own engines section documents the 2.3-liter (138 cu in) High-Output Quad 4, a DOHC 16-valve four-cylinder with multiport fuel injection at 10.0:1 compression, rated 180 hp at 6,200 rpm and 160 lb-ft at 5,200 rpm SAE net, standard on the Calais International Series and optional on the Calais S. This record's own transmissions section documents the five-speed manual sport-ratio transaxle paired with the High-Output Quad 4 in the Quad 442 package.

This record's own conflicts section addresses the 1991 Quad 442 engine rating directly: the factory catalogue lists only the 180 hp, 160 lb-ft High-Output Quad 4, while a tertiary source gives 190 hp for a 1991 W-41 package. This record's own treatment shows both, noting that the factory catalogue lists only the 180 hp engine and that the tertiary 190 hp W-41 claim may describe a different or later package the catalogue does not show.¹

This record's own options section documents the Quad 442 Sport Performance Package's contents: a gold stripe, black trim, the High-Output Quad 4, the five-speed manual, a Rallye instrument cluster, 15-inch wheels (14-inch aluminum-styled on early cars), performance tires, a rear aero wing, variable-effort steering, a handling suspension, and a leather-wrapped steering wheel, noting the 1991 catalogue gives no RPO code though the 1990 catalogue lists the package as W40. This record's own prices section documents the package at $1,721, alongside a $11,495 factory price for the Cutlass Calais S coupe (F27), and this record's own production rows document a 6,906-car Cutlass Calais S coupe host-body total shown for scale only, since no Quad 442 installation count was found in a citable source.³

This record's own specifications section documents a 103.4-inch wheelbase, a 179.3-inch length, a 66.9-inch width, and a 52.4-inch height for the Calais coupe, a 2,518-lb base curb weight not stated as Quad 442-specific, and a 13.6-gallon fuel tank. This record's own paint section documents ten Cutlass Calais colors without stating which the Quad 442 package specifically offered, and this record's own unpublished leads flag an uncited Wikipedia claim of Quad 442 production split as 1,160 W-40 and 204 W-41 cars, a figure this record does not adopt for lack of a named source.
