With the goal of reducing energy consumption in the 1970s and beyond, the U.S. Congress enacted the Corporate Average Fuel Economy (CAFE) program. The CAFE program consists of two components: setting fuel economy standards for cars and light trucks (administered by the NHTSA) and calculating the average fuel economy for automotive manufacturers (the job of the EPA). If a manufacturer doesn’t meet the current year standard, they have to pay a fine. Window sticker EPA fuel economy estimates and CAFE standards are different. The window sticker shows a tank-to-wheel or battery-to-wheel fuel economy, not taking into account the energy to produce and deliver a fuel. The CAFE fuel economy estimate is well-to-wheel, including an adjustment for alternatives that provides a higher miles per gallon of gasoline equivalent (MPGe).
