MPG Estimates from Other Drivers
Average user estimates are based on data from My MPG users—drivers like you—rather than official sources. Since the source data cannot be verified, neither DOE nor EPA guarantees the accuracy of these estimates.
- The Average MPG is the fuel economy averaged across all drivers sharing data.
- The Range gives the average MPG for the shared vehicles with the best and worst average fuel economy.
Cost to Drive
Annual Fuel Cost
Annual Fuel cost estimates assume you will drive 15,000 miles each year, 45% of which will be under highway driving conditions (steady speeds with little or no stopping), 55% in city driving (low speeds with lots of stopping), 15,000 annual miles and current national average fuel prices. You may personalize these values to reflect the price of fuel in your area and your own driving patterns.
Cost to Refuel
Cost to completely refuel the vehicle when the tank is 100% empty.
Distance on a Full Tank
The distance the vehicle can go from a full tank down to 100% empty. U.S. or metric units can be displayed depending on the setting in Personalize.
Greenhouse Gas Emissions
This measure shows a vehicle's impact on climate change in terms of the amount of greenhouse gases, mostly carbon dioxide (CO2), it emits. Your choice of vehicle has the biggest impact on your overall contribution to climate change.
We provide two kinds of greenhouse gas (GHG) emission estimates:
- Tailpipe-only CO2 emissions
- Tailpipe and "upstream" GHG emissions (CO2 and other GHGs)
If a vehicle can operate on more than one type of fuel, an estimate is provided for each fuel type.
These estimates include CO2 emitted from the vehicle's tailpipe and are displayed grams per mile. Note: Tailpipe CO2 is estimated using an EPA emissions factor and does not reflect direct test results.
Tailpipe and Upstream Emissions
These estimates include CO2, methane, and nitrous oxide emitted from all steps in the use of a fuel, from production and refining to distribution and final use—vehicle manufacture is excluded. Methane and nitrous oxide emissions are converted into a CO2 equivalent.
EPA Smog Score
The EPA Smog Score represents the amount of health-damaging and smog-forming airborne pollutants the vehicle emits. Scoring ranges from 1 (worst) to 10 (best). This score does not include emissions of greenhouse gases (see Greenhouse Gas Emissions).
Vehicles that receive the SmartWay certification are very good environmental performers relative to other vehicles. They must attain a better-than-average EPA Smog Score and Greenhouse Gas Emission Score.The SmartWay Elite certification is reserved for those vehicles that attain the best smog and greenhouse gas scores.
Annual Petroleum Use
Each vehicle in our Find and Compare Cars section includes an estimate of the amount of petroleum it uses each year. The estimate includes both petroleum consumed by the vehicle as well as petroleum used in manufacture and transportation of the fuel. You can help reduce our dependence on imported oil by selecting a vehicle that uses less petroleum.
Clicking the Personalize button at the bottom of the page allows you to enter information about your annual mileage, the percentage of miles you drive in city vs. highway driving conditions, and your local fuel prices so that we can provide estimates just for you.
Frequently Asked Questions
What's the difference between air pollution and greenhouse gas emissions?
The air pollution score and carbon footprint measure different types of vehicle emissions. Air pollutants harm human health and/or cause smog. Carbon footprint measures greenhouse gas emissions (primarily CO2) that impact climate change.
