Corporate Average Fuel Economy

Corporate Average Fuel Economy is a term from the U.S. legislation on motor vehicles.

It is the weighted by market share fleet consumption of vehicles of one manufacturer, calculated in " miles per gallon" (mpg ), of all vehicles (cars and light trucks ), the mass ( "gross vehicle weight rating", GVWR ) of less than 8,500 lbs. (Pounds, about 4000 kg ), and were manufactured for sale in the USA, based on each model year.

The term "fuel economy" ( frugality in fuel consumption) is defined as the average route miles traveled by an automobile per gallon of gasoline ( or equivalent amounts of other fuels ), in accordance with the test regulations of the EPA (Environmental Protection Agency ).

In 1975, the U.S. Congress first put consumption limits for cars and small trucks fixed in response to the oil embargo of 1973. During 2007, the Bush administration refused to allow the state of California and 13 other states to establish stricter consumption limits. Automakers such as GM and Ford then took the view that it was not them be expected to follow two different standards. In March 2009, the Obama administration has intensified the unchanged applicable limits since 1985, and announced in May 2009 to implement the proposed limits of California until 2016. These are about 30% under the current limits.

The list of automobile manufacturers who had to do in 2010 penalties after the CAFE legislation due to high consumption fleet includes Mercedes -Benz, Jaguar, Porsche, Fiat, and Volvo.
