Fuel Economy Database: Automobile MPG estimates, 1979-2010 (US DOE / EPA)

Added By mrflip helps consumers make informed fuel economy choices when purchasing a vehicle and helps them achieve the best fuel economy possible from the cars they own. is maintained jointly by the U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy and the U.S. Environmental Protection Agency. The site helps fulfill DOE and EPA’s responsibility under the Energy Policy Act (EPAct) of 1992 to provide accurate MPG information to consumers. provides fuel economy estimates, energy and environmental impact ratings, fuel-saving tips, and other useful information.

How was the data gathered?

The data included in the Department of Energy’s Fuel Economy Guide are the result of vehicle testing done at the Environmental Protection Agency’s National Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan and by vehicle manufacturers themselves with oversight by EPA. All of the data files are comma delimited text files for import into database or spreadsheet tables. The 1998, and 1999, are also available as an excel spreadsheet. The data files have been compressed. A

• A tool to estimate, record and track on-road fuel economy

How are fuel economy estimates obtained?

EPA estimates are based on laboratory tests conducted by manufacturers according to federal regulations. EPA re-tests about 10% of vehicle models to confirm manufacturer’s results. For more detailed information, visit our page on How Vehicles Are Tested.

Why does my fuel economy differ from EPA estimates?

No test can accurately predict fuel economy for all drivers and all driving conditions. Driver behavior, driving conditions, vehicle maintenance, fuel characteristics, weather, and other factors can all affect fuel economy significantly as explained here.

Why don’t you have ratings for large vans, pickup trucks and SUVs?

Vans, pickup trucks, and sport utility vehicles (SUVs) weighing more than 8,500 pounds gross vehicle weight are classified as heavy-duty vehicles. Fuel economy regulations do not apply to these vehicles, so they are not tested. Additional information is available at Which Vehicles Are Tested?
