STORY
The Geo Storm was a front-drive sport coupe sold from 1990 to 1993 under GM's Geo marque, a rebadged version of Isuzu's second-generation Impulse. The base car had a single-cam 1.6 rated at 95 hp, and the GSi a twin-cam 1.6 with 130 hp. For 1992 the GSi moved to a 1.8 with 10 more horsepower. A hatchback body joined the original coupe for 1991, but only the coupe remained for 1993, the final year, when the base engine fell to 90 hp.
