Under the hood sits the same overhead-valve 3.8-liter V6 that has powered full-size GM cars since they were switched to front-wheel drive in 1986. However, GM adds more horsepower, with 1992 models featuring a 170-horsepower at 4800 rpm and 220 pound-feet of torque at 3200 rpm. For the sporty 1992-93 SSEi models, Pontiac provides a supercharged edition that delivers 205 horsepower at 4400 rpm and 260 pound-feet of torque at 2800 rpm. Both V6 engines comes paired with an electronic 4-speed overdrive transmission. For 1993, torque on the base engine rises slightly to 225 pound-feet at 3200 rpm, with an all-new engine arriving in 1995. The new unit is a reengineered 3.8-liter, called the Series II 3800 V6. In its new form it delivers 205 horsepower--35 more than before--and 230 pound-feet of torque, up 5 from the previous version. For '94, the more potent 225-horsepower supercharged edition of the V6 is available for those ordering the SSEi Supercharger Package. It provides 275 pound-feet of torque at 3600 rpm. Both engines remain teamed with an electronic 4-speed automatic transmission. For 1996, power for the optional supercharged engine jumps to 240 horsepower at 5200 rpm and 280 pound-feet of torque at 3200 rpm.
