Fuel Economy Overview

The 1984 Isuzu I-Mark achieves an EPA-estimated 35 MPG in combined city and highway driving, with 33 MPG in the city and 38 MPG on the highway. Powered by a 1.8L 4-cylinder engine paired with a manual 4-spd, this subcompact cars .

In terms of environmental impact, the 1984 I-Mark produces approximately 291 grams of CO2 per mile. This figure is measured under standardized EPA test conditions and represents tailpipe emissions only. For context, the average new vehicle sold in the United States produces approximately 400 grams of CO2 per mile, meaning this I-Mark performs better than the national average in this regard.

The estimated annual fuel cost for this vehicle is $2,300, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $750 over a 5-year period. This calculation accounts for differences in fuel consumption efficiency and provides a practical measure of long-term ownership costs attributable to fuel economy.
