The purpose of this legislation, known as the Restoring Affordability in Automobile Manufacturing Act, is to eliminate existing corporate average fuel economy (CAFE) standards. These standards set requirements for the average fuel efficiency of vehicles produced by manufacturers. The bill aims to make automobile manufacturing more affordable by removing these regulations, which some lawmakers believe impose financial burdens on manufacturers. Key provisions of the legislation include the complete repeal of the CAFE standards starting with model year 2029 and beyond.
