Year to Year Changes
1991 Isuzu Impulse:
An extended-roof hatchback coupe, with Kammback-like rear styling, joined the original model this year. Antilock braking was optional on the RS edition.
1992 Isuzu Impulse:
A more-powerful engine went into this year's Impulse coupes and hatchbacks. The XS edition got a dual-cam, 1.8-liter 4-cylinder that produced 140 horsepower. It replaced the former 130-horsepower, 1.6-liter powerplant. As before, the RS featured a turbocharged version of the 1.6-liter, rated at 160 horsepower. Otherwise, little changed in what would be the model's final season. The similar Geo Storm continued into the 1993 model year.
