EPA FUEL ECONOMY

Laboratory fuel economy tests administered by the Environmental Protection Agency (EPA) using simulated weight and drag to re-create real driving conditions. The city fuel-economy test, also used to test emissions compliance , is based on a drive through typical Los Angeles urban traffic of about twenty years ago. Such conditions in LA are no longer present. The highway test uses a higher, steadier speed , averaging 79.5 kph (49.4 mph).
