CAFE (Corporate Average Fuel Economy) standards are mile-per-gallon targets for cars and trucks set by the U.S. government. In 2009, the government set a fuel economy standard of 34.1 mpg for cars and light trucks by 2016. In its final ruling in January, the EPA estimated the fuel economy standards will cost $875 per vehicle. They also could scrap subcompact cars, which are unpopular with U.S. consumers but help meet fuel economy targets. Automakers will still have to meet rising fuel economy standards in China and Europe, so they won't stop making efficient vehicles.
