Lot CCR79GMC9204: 1979 GMC Jimmy

For a 1979 GMC Jimmy with the 350 cubic-inch V8 engine, you can typically expect:

City driving: 12-15 mpg Highway driving: 16-18 mpg Combined real-world driving: 13-16 mpg

These figures are consistent with EPA data from the era and owner reports. The Jimmy’s full-size SUV design and 4WD system contribute to these fuel consumption numbers, which were competitive with similar vehicles of that era like the Ford Bronco and Jeep Cherokee.

Would you like me to help you find similar vehicles with better fuel economy, or do you have other questions about this Jimmy?
