Quick Facts - EPA Mileage Estimates
The EPA estimated fuel economy numbers are derived from vehicle testing
conducted at the U.S. Environmental Protection Agency’s (EPA’s) National
Vehicle and Fuel Emissions Laboratory in Ann Arbor, Michigan. Vehicle
manufacturers also submit test results based on strict EPA standardized drive
patterns. Each year, the EPA provides the data to the Department of Energy,
which publishes the results at www.fueleconomy.gov.
Some quick facts about EPA estimated fuel economy tests:
Federal law requires EPA estimated fuel economy to be provided on a fuel
economy label affixed to the window of every vehicle (see Figure 1). The EPA
estimates serve as a useful guide for comparing the relative fuel efficiency of
various vehicles and are intended for comparison only. Fuel economy estimates
are determined under ideal laboratory conditions following a standardized test
determined by federal law. Each vehicle must complete tests simulating a driving
routine for:
• City - Low speeds in stop-and-go urban traffic.
• Highway - Free-flow traffic at highway speeds.
• High Speed - Higher speeds; harder acceleration and braking.
• AC - Air conditioner use under hot ambient conditions.
