This record's own dek states that the W42 4-4-2 returned on the rear-drive Cutlass Supreme, with a 307 V-8 and a four-speed automatic. This record's own overview states that the 4-4-2 returned as the W42 package on the rear-drive G-body Cutlass Supreme, and that a tertiary account says the name now referred to the four-speed 200R4 automatic and that the 307 V-8 was the only engine.1

This record's own key facts state that 1985 production is disputed between two reference books: the Standard Catalog of American Cars says 3,000 4-4-2 packages (RPO W42) were produced, while Consumer Guide's Complete Book of Collectible Cars gives 3,500 for the 1985 Salon 4-4-2, and that the uncited 3,000 figure in the Wikipedia article matches the Standard Catalog rather than serving as independent confirmation. This record's own conflicts section shows both figures with attribution, marked disputed, and treats the Standard Catalog as the more specific source since it names the RPO code and says the packages "were produced." This record's own key facts also state that Ate Up With Motor puts 1985 production at "about 3,000" without naming a record, leaving the exact figure unconfirmed.2,3

This record's own key facts state that Oldsmobile's 1985 "Three for the Road" folder lists the Cutlass 442 package in white, medium gray metallic, or black over silver metallic with gold stripes, with a 5.0-liter four-barrel V-8 and dual-outlet exhaust, a four-speed overdrive automatic, a 3.73 axle, air rear shocks, and P215/65R15 Eagle GT tires, air conditioning (C60) mandatory. This record's own options section documents the W42 package priced at $1,175 on the Cutlass Supreme coupe, and a separately listed "4-4-2/Olds Package (Salon only)" in Oldsmobile's Cutlass Supreme available-equipment list.

This record's own production rows carry two competing 4-4-2 figures, 3,000 from the Standard Catalog and 3,500 from Consumer Guide, both round numbers with neither book naming a record behind it, alongside a separately scoped 17,512-car Cutlass Salon coupe host-body total shown for scale only. This record's own production notes state that none of these rows may be added together, and that an Oldsmobile production or option-installation report would be needed to settle the 1985 total.2

This record's own prices section documents the 4-4-2 package at $1,175, alongside factory prices of $10,770 for the Cutlass Salon coupe (K47) with the V-6 and $11,060 with a V-8. This record's own specifications section documents a 3.73 axle ratio, P215/65R15 Goodyear Eagle GT tires with white-outlined letters on chrome styled wheels with gold accent, Oldsmobile's own claimed 0-60 mph time of 9.8 seconds "on the test track" rather than an independent test, and 16.2 cubic feet of luggage space.2

This record's own unpublished leads flag an enthusiast source's uncited claim of a $1,275 W-42 option price with air conditioning required at about $600 more, a VIN engine code 9, an LG8 5.0 H.O. engine designation, and an MX0 transmission code; a forum-only claim that 200 of the W42 cars carried the Z49 Canadian export package, 29 of them white; and a Car and Driver test paraphrased by a secondary source at roughly 9 seconds to 60 mph and a 113 mph top speed, not added as a performance row because the magazine itself was not read.1

The numbers

1985 Oldsmobile Cutlass Supreme 4-4-2 — The W42 4-4-2 on the rear-drive Cutlass Supreme, with a 307 V-8 and a four-speed automatic.

Coverage: Partial — researched sections are shown; missing ones are not yet sourced. Researched through 2026-09-23.

Every figure is labeled with how sure we are. Reported means a manufacturer, registry, or reference figure we cite but have not reconciled against factory records ourselves. Disputed means credible sources disagree and both are shown. Rows are separately scoped; don't add them together unless the note says they make up a total.

Key facts

  • Production is disputed between two reference books: the Standard Catalog of American Cars 1976-1999 says 3,000 4-4-2 packages (RPO W42) were produced, while Consumer Guide's Complete Book of Collectible Cars gives 3,500 for the 1985 Salon 4-4-2. The uncited 3,000 in the Wikipedia article matches the Standard Catalog.2,3,1
  • Oldsmobile's 1985 "Three for the Road" folder lists the Cutlass 442 package: white, medium gray metallic or black over silver metallic with gold stripes, 5.0 liter four-barrel V-8 with dual-outlet exhaust, four-speed overdrive automatic, 3.73 axle, air rear shocks and P215/65R15 Eagle GTs, with air conditioning (C60) mandatory.
  • Ate Up With Motor puts 1985 production at "about 3,000" without naming a record; the exact figure remains unconfirmed.4

What was countedCountBasisStatus
Cutlass Salon coupe (K47), all engines and packages (4-4-2 host body)2 Cutlass Salon · 2-door coupe (K47) · not stated Host-body total; the catalogue lists the 4-4-2 package against the Salon in its option prices. Not a 4-4-2 count. 17,512 not stated (catalogue production total), model-year Reported

The two 4-4-2 rows are competing figures for the same cars (see conflicts); the host-body row is separately scoped. None of the rows may be added.

An Oldsmobile production or option-installation report would settle the 1985 total.

Searched 2026-09-29: musclecarclub.com's Oldsmobile 442 page (fetched 2026-09-29) gives 3,000 for 1985 without a source, the same as the Standard Catalog figure and the uncited Wikipedia line, so it does not break the dispute with the 3,500 Consumer Guide figure. Barn Finds repeats the 3,000/4,273/4,208 series and links Wikipedia as its basis. No Oldsmobile record was found.

Where the sources disagree

1985 4-4-2 (W42) production

  • 3,000 packages produced2
  • 3,500 (Salon 4-4-2)3

Both figures are shown with attribution and marked disputed. Both are round numbers and neither book names its record; the Standard Catalog is the more specific (it names RPO W42 and says 'produced'). The uncited 3,000 in the Wikipedia article is probably the Standard Catalog lineage, so it does not count as a second confirmation.
