What Trump's rollback of fuel economy standards means for drivers

Key Points:

• The Trump administration has rolled back stricter federal fuel economy standards set during the Biden administration, lowering the required fleet-wide average fuel efficiency for new vehicles to 34.9 miles per gallon by 2031, down from over 50 miles per gallon under Biden-era rules.
• This rollback relaxes pollution control requirements and reduces the pressure on automakers to produce electric vehicles (EVs), aligning with a strategy to make gas-powered vehicles more affordable and accessible amid rising oil prices due to the war in Iran.
• The administration claims the changes will reduce new vehicle costs by approximately $1,300, but experts note that fuel costs over the vehicle's lifetime could increase by about $1,600, potentially offsetting upfront savings for consumers.
• Automakers generally favor the rollback as it reduces compliance costs and removes mandates pushing EV production, but environmental groups warn it will lead to higher gasoline consumption and increased emissions, with estimates suggesting up to 5% more gasoline use through 2050.
• Consumers may see some lower-priced vehicle options in the coming years, but with the removal of regulatory incentives and tax credits for EVs, the market will largely depend on consumer demand and automaker choices, with California remaining the only state enforcing stricter standards.
