By the 2032 model year, the U.S. government hopes to increase new car fuel efficiency by 18%, resulting in a fleet that gets an average of 43.5 miles per gallon when driven in actual traffic.
The National Highway Traffic Safety Administration, which will finally set the official mileage standards, announced the tentative numbers on Friday.
According to corporate average fuel economy rules put in place by President Joe Biden’s administration, which overturned a reversal by the administration of former President Donald Trump, the fleet of new vehicles must currently average 36.75 mpg by 2026.
According to the highway safety agency, it will make an effort to align its rules with the Environmental Protection Agency’s cuts in greenhouse gas emissions.
However, if there are differences, automakers will probably need to adhere to the strictest standards. Since burning less gasoline is the quickest way to cut carbon emissions, both agencies are essentially in charge of setting fuel economy standards in the confusing world of government regulation.
Acting NHTSA Administrator Ann Carlson stated, “I want to be clear that EPA and NHTSA will work to enhance the effectiveness of both agency standards while lowering compliance costs.
The standards from the agencies should be aligned, according to a significant trade group for the auto sector, which comprises General Motors, Toyota, Ford, Stellantis, and other companies.
According to John Bozzella, CEO of the Alliance for Automotive Innovation, “an automaker shouldn’t be at risk of breaking CAFE rules (from NHTSA) and subject to civil penalties if they comply with the EPA’s yet-to-be-finalized greenhouse gas emissions rules.
However, according to the alliance, the EPA’s anticipated reduction in carbon emissions will necessitate a sharp increase in the sales of electric vehicles, which will not be possible by 2032.
The EPA estimates that if 67% of new cars sold in 2032 are electric, the industry can meet its greenhouse gas emission targets. Currently, 7% of all new car sales are EVs.
According to the NHTSA, their plan would result in a 4% rise for light trucks and a 2% annual improvement for passenger cars’ fuel economy. It suggests an annual improvement of 10% for work vans and pickup vehicles.
With a combination of electric vehicles, gas-electric hybrids, and efficiency enhancements in gas and diesel vehicles, automakers may achieve the standards.
