In his State of the Union address, President Bush called for reforming and increasing CAFE standards for cars, and for further increasing light truck and SUV standards. CAFE, which is the Corporate Average Fuel Economy (CAFE)
is measured by the sales weighted average fuel economy, expressed in miles per gallon (mpg), of a manufacturer’s fleet of passenger cars or light trucks with a gross vehicle weight rating (GVWR) of 8,500 lbs. or less, manufactured for sale in the United States, for any given model year. Fuel economy is defined as the average mileage traveled by an automobile per gallon of gasoline (or equivalent amount of other fuel) consumed as measured in accordance with the testing and evaluation protocol set forth by the Environmental Protection Agency (EPA).
By relying on new technologies the President believes that the US can significantly improve fuel economy without impacting safety. The goal of the President's energy plan is to reduce fuel consumption by up to 8.5 billion gallons in 2017.
