The 900S comes with a 2.3-liter 4-cylinder, previously available only in the Saab 9000. It provides 150 horsepower at 5700 rpm and 155 pound-feet of torque at 4300 rpm. The 900SE 5-door comes with the new V6, a 2.5-liter unit derived from one used by both Vauxhall and Opel. It delivers 170 horsepower at 5900 rpm and 167 pound-feet of torque at 4200 rpm. With both engines, a 5-speed manual is standard and a 4-speed automatic is optional. The automatic is Saab's first 4-speed unit and features electronic controls that provide a choice of "sport," "economy," or "winter" settings. The latter allows the car to start out in third gear, to avoid wheel spin. While awaiting the arrival of new convertible models, Saab continues to sell holdover ragtops with either the 2.1-liter engine or the old 2.0-liter turbocharged 4-cylinder. The 2.1-liter offers 140 horsepower at 6000 rpm and 133 pound-feet of torque at 2900 rpm. Saabs turbocharged 4-cylinder from the '93 model provides 160 horsepower at 5500 rpm and 188 pound-feet of torque at 4300 rpm. Saab is also providing 500 Commemorative Edition versions of these convertibles (both 900 and 900 Turbo models) with special black paint and trim, with the more potent 2.0-liter turbocharged 4-cylinder delivering 185 horsepower at 5500 rpm and 1994 pound-feet of torque at 2100 rpm.
