The End of Fuel Economy Rules: A New Era for American Car Buyers and Manufacturers The United States has a long history of regulating fuel economy standards, dating back to the 1970s when Congress passed the Corporate Average Fuel Economy (CAFE) standard as part of the Motor Vehicle Information and Cost Savings Act.
This landmark legislation aimed to reduce America's dependence on foreign oil by improving the fuel efficiency of new vehicles.
Over the years, CAFE has undergone several revisions, with the most recent updates implemented in 2012 under President Barack Obama's administration.
