Detailed Test Information
EPA tests vehicles by running them through a series of driving routines, also called cycles or schedules, that specify vehicle speed for each point in time during the laboratory tests.
For 2007 and earlier model year vehicles, only the city and highway schedules were used. Beginning with 2008 models, three additional tests are used to adjust the city and highway estimates to account for higher speeds, air conditioning use, and colder temperatures.
EPA has established testing criteria for electric vehicles and plug-in hybrids that are slightly different than those for conventional vehicles.

* A vehicle's engine doesn't reach maximum fuel efficiency until it is warm.
