Cutlass Supreme — W-body (1988–1997)

1991–1996 Single-source

Wikipedia's Cutlass Supreme engine table prints LQ1 for 1991–1995 (210 hp) and 1996 (215 hp), and its text puts the end of the 3.4L option in 1996; its 60° V6 article lists the car under LQ1 for 1991–1996 (not independent); the 1994 power teams page (p.5) prints LQT, so 1994 is cited from the weight page; the 1995 Monte Carlo order guide words the engine 3.4 liter SFI V6, while the weight pages write MFI; shared W-body code; cited from the Chevrolet Lumina kit (1991–1994, 1996) and the Chevrolet Monte Carlo kit (1995)
