Powertrain Options and Availability
Pontiac base SE model comes equipped with the single overhead-camshaft Quad OHC. At introduction, it provides 120 horsepower at 5200 rpm and 140 pound-feet of torque at 3200 rpm. It comes with a manual 5-speed and optional 3-speed automatic. Optional for the SE is a dual-overhead-cam Quad 4, producing 160 horsepower at 6200 rpm and 155 pound-feet of torque at 5200 rpm. The automatic is the only gearbox provided. The Grand Am GT comes standard with a High-Output, double-overhead-cam version of the Quad 4. It pumps out 180 horsepower at 6200 rpm and 160 pound-feet of torque at 5200 rpm. Engineering changes for '93 result in all three 4-cylinder engines losing five horsepower. Optional for both the SE and GT versions is a new V6 powertrain. Paired with a 3-speed automatic, GM's 3.3-liter V6 is the first to appear under the hood of a Grand Am since 1987. It delivers 160 horsepower at 5200 rpm and 185 pound-feet of torque at 2000 rpm. A 4-speed automatic arrives for '94, along with a smaller 3.1-liter V6 replacing the 3.3-liter unit. It generates 155 horsepower at 5200 rpm and 185 pound-feet of torque at 4000 rpm. A revised, 150-horsepower Quad 4 with balance shafts arrives in '95, while for '96 the Quad OHC base engine is replaced with a new 2.4-liter Twin Cam. It produces 150 horsepower at 6000 rpm and 150 pound-feet of torque at 4400 rpm. It's paired with either the standard 5-speed manual or optional 4-speed automatic gearbox.
