This single-model year standard was issued March 27, 2009, and is about one mpg lower than the fuel economy standards previously recommended under the Bush Administration. "These standards are important steps in the nation's quest to achieve energy independence and bring more fuel efficient vehicles to American families", said Secretary LaHood.
The U.S. Energy Policy Act of 2005 established a federal income tax credit of up to $3,400 for the purchase of new hybrid vehicles, purchased or placed into service after December 31, 2005. [ 1 ] [ 2 ] Vehicles purchased after December 31, 2010 are not eligible for this credit.

Example energy flows for a late-model (pre-2009) midsize passenger car: (a) urban driving; (b) highway driving. Source: U.S. Department of Energy [4] [5] Most of the fuel energy loss in cars occurs in the thermodynamic losses of the engine. Specifically, for driving at an average of 60 kilometres per hour (37 mph), approximately 33% of the ...
Fuel efficiency (or fuel economy) is a form of thermal efficiency, meaning the ratio of effort to result of a process that converts chemical potential energy contained in a carrier into kinetic energy or work.
The following table compares official EPA ratings for fuel economy (in miles per gallon gasoline equivalent, mpg-e or MPGe, for plug-in electric vehicles) for series production all-electric passenger vehicles rated by the EPA for model years 2015, [1] 2016, [2] 2017, [3] and 2023 [4] versus the model year 2016 vehicles that were rated the most efficient by the EPA with plug-in hybrid ...
Small fuel-efficient cars from foreign automakers took a sharply higher share of the U.S. auto sales market. Under the Energy Policy and Conservation Act [ 42 ] the federal government initiated fuel efficiency standards (known as Corporate Average Fuel Economy , or CAFE) in 1975, effective as of 1978 for passenger cars, and as of 1979 for light ...
