The Transportation Department on Sept. 28 released final fuel economy standards that sharply lower requirements for new cars and light trucks, and environmental and public health groups immediately pledged to challenge the rule. The National Highway Traffic Safety Administration projects the standards will produce a fleetwide average of 34.9 miles per gallon by model year 2031, up from 30.1 mpg in model year 2024, according to the Transportation Department's announcement.
