| Engines | ||||
| LN7 | Engine, 3.0L V6, 181 cu in, multiport fuel injection (VIN L) | 1985–1988 | shared N-body code; cited from the Buick Somerset; optional Buick V6, 125 hp, with the automatic only (Wikipedia's Calais article); Wikipedia's Buick V6 engine article prints LN7 and VIN code L and lists the Calais for 1985–1988; gnttype.org's 1986 and 1987 Buick VIN tables print LN7 on the Somerset rows, sibling corroboration of the code (T3; it names the code on a Somerset, not a Calais, so it does not lift the row); its 1985 table repeats the 1986 table | Single-source |
| LD2 | Engine, 2.3L L4, DOHC, fuel injection (Quad 4) | 1988–1991 | Oldsmobile-built, 150 hp in 1988–1989 and 160 hp from 1990; Wikipedia's Quad 4 engine article lists the Cutlass Calais under LD2 for 1988–1991 and says the engine reached production on the 1988 Calais; the Calais article says the Quad 4 was available on all models from 1988 and lists it from 1987 (1987 is left out because the Quad 4 article dates the engine's introduction to the 1988 model year); not independent of each other; the description says fuel injection without the multiport wording because the Quad 4 article gives no more detail (the merged Pontiac Grand Am doc reads its Quad 4 rows as multiport fuel injection) | Single-source |
| LG0 | Engine, 2.3L L4, DOHC, high output, fuel injection (Quad 4) | 1990–1991 | 180 hp, 5 speed manual only; Quad 442 and International Series; Wikipedia's Quad 4 article lists the International Series for 1989–1991 and the Quad 442 for 1990–1991, while the Calais article's engine list gives the 180 hp engine for 1990–1991 only, so 1989 is left out; not independent of each other | Single-source |
| W41 | Engine, 2.3L L4, DOHC, high output, W41 (Quad 4) | 1991 | 190 hp, Quad 442, 5 speed manual only with a 3.94 final drive; the Calais article's engine list dates the W41 car to 1991 and the Quad 4 article lists the Calais 442 for 1990–1991, so only 1991 is claimed; not independent of each other | Single-source |
| LG7 | Engine, 3.3L V6, 204 cu in | 1989–1991 | shared N-body code; 160 hp, replaced the 3.0L V6; Wikipedia's Buick V6 engine article names the 3300 as LG7 and lists the Calais for 1989–1991, and the Calais article's engine list gives the 3300 for the same years (not independent); gnttype.org's Buick tables do not print it | Single-source |
| Equipment | ||||
| FE3 | Suspension, sport tuned | 1986 | the GT and ES trims; Wikipedia's Calais article says the 1986 GT and ES had the FE3 sport tuned suspension and that the International Series came with the FE3 sport suspension as standard (that sentence is undated, so no later year is claimed); matched to the Calais by the article's text | Single-source |
