Powertrain Options and Availability
For its first two seasons, the Storm had a choice of two 1.6-liter engines: a single-cam version in the base model, rated 95 horsepower; or a dual-cam rendition that made 130 horsepower, for the GSi. Three transmissions were available. A 5-speed manual gearbox was standard; 3-speed automatic optional on the base model, but 4 speed automatic on the GSi. For 1992, the GSi traded its 1.6-liter engine for a 1.8-liter, with 10 more horsepower and 18 more pound-feet of torque. The base engine lost five horsepower in 1993.
