Fuel Economy Test Procedures and Labeling

The U.S. Environmental Protection Agency (EPA) is responsible for motor vehicle fuel economy testing. Manufacturers test their own vehicles and report the results to EPA. EPA reviews the results and confirms a portion of them using their own testing facilities. To aid consumers shopping for new vehicles, EPA redesigned the fuel economy window sticker posted on all new cars and light trucks starting with Model Year 2013 vehicles to be easier to read and understand. EPA also redesigned fuel economy window stickers for electric and other advanced vehicles. EPA is responsible for providing the posted fuel economy data and does so through the FuelEconomy.gov website. For more information, visit EPA's Fuel Economy website. (Reference 40 CFR 600)
