On 7 June 2024 the U.S. Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) issued “new vehicle fuel economy standards that it calculated will save Americans more than $23 billion in fuel costs while reducing pollution. This rule is in accordance with continuous energy security efforts that date back to the 1970s, when the average vehicle got about 13 miles to the gallon.

“In this final rule, fuel economy will increase 2% per year for model years 2027-2031 for passenger cars, while light trucks will increase 2% per year for model years 2029-2031. These increases will bring the average light-duty vehicle fuel economy up to approximately 50.4 miles per gallon by model year 2031, saving passenger car and light truck owners more than $600 in fuel over the lifetime of their vehicles
