The Biden administration aims to lower fuel consumption to an average of 58 miles per gallon across the U.S. fleet.
The new fuel-economy standards proposed by the National Highway Traffic Safety Administration would increase cars’ fuel efficiency by 2% per year and light trucks by 4% annually starting with model year 2027.
The new standards complement those of the Environmental Protection Agency’s emissions rules proposed in April that are the strictest on record and push automakers to make the majority of their sales electric vehicles. Many Republican lawmakers are fighting those rules, saying they go too far.
The new NHTSA-proposed Corporate Average Fuel Economy standards would achieve the new average miles per gallon by model year 2032. They include a requirement that heavy-duty pickups and work vans’ fuel economy increase 10% per year from models years 2030 to 2035.
“Better vehicle fuel efficiency means more money in Americans’ pockets and stronger energy security for the entire nation,” said U.S. Transportation Secretary Pete Buttigieg in a press release about the new standards.
