Fuel economy numbers are determined by measuring a vehicle’s emissions in laboratory conditions. Each vehicle goes through a controlled series of laboratory tests that are mandated by federal law. The manufacturers themselves conduct these tests, and then report their results to the United States Environmental Protection Agency. These tests occur in state-of-the-art facilities in a highly-controlled environment.
City and highway fuel economy numbers are different because vehicles are, on average, less efficient in the city. The stop-and-start driving that occurs in urban environments are inherently less efficient than highway driving, which is more gradual in comparison. Because of this, the EPA gives each vehicle three fuel economy ratings: A city rating, a highway rating and a combined (45% city, 55% highway) rating.
