Sixth generation

1990–1991

Main article: Oldsmobile Cutlass Calais

The 4-4-2 option was revived on the Quad 4-4-2 front-wheel drive 1990–1991 Cutlass Calais. This model used a 2.3 L LG0 Quad-4 4-cylinder engine with 4 valves per cylinder and 2 camshafts. The engine was tuned with higher output camshafts which produced more top end power at the expense of idle quality. It used a single exhaust with a dual tipped muffler and produced 180 hp (134 kW) with a 5-speed manual transmission.

This version of the 4-4-2 also played upon the "W-30" option code used in past versions of the 4-4-2, the exception being that this model used the option code "W-40". A low production, late 1991 model year version used the option code "W-41"; the key differences of "W-41" package was a 190 hp (142 kW) engine with a different geared 5 speed transmission.

This 4-4-2 model lasted just two years.

Production totals:

1990 "W-40" = 2629

1991 "W-40" = 1160

1991 "W-41" = 204

GM literature referred to the 1992 & 1993 Oldsmobile Achieva SCX as a 4--42, the last time the designation was used. The Achieva SCX used the same 'W41' drive train as the very limited production 1991 4-4-2-W41.
