& Fuel Economy

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.
