1991 Mazda Navajo
Fuel Economy Overview
The 1991 Mazda Navajo achieves an EPA-estimated 16 MPG in combined city and highway driving, with 15 MPG in the city and 19 MPG on the highway. Powered by a 4L 6-cylinder engine paired with a manual 5-spd, this special purpose vehicles features 4-Wheel or All-Wheel Drive drive.
In terms of environmental impact, the 1991 Navajo produces approximately 555 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 Navajo has higher-than-average emissions in this regard.
The estimated annual fuel cost for this vehicle is $3,750, based on 15,000 miles of driving per year and current national average fuel prices. Compared to the average new vehicle, you would save $8,000 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.

Adjust the slider to match your daily driving habits. City driving involves stop-and-go traffic under 45mph, while highway driving represents sustained speeds over 55mph.
Aerodynamic Speed Penalty
EPA highway tests average roughly 48 mph. Driving at 75 mph increases aerodynamic drag exponentially. Expect your real-world highway fuel economy to drop by roughly 15-20% at interstate speeds.
