EPA, NHTSA fail to address high-octane fuel in SAFE Vehicles rule

The U.S. EPA and U.S. Department of Transportation’s National Highway Traffic Safety Administration released the final Safer Affordable Fuel-Efficient (SAFE) Vehicles rule on March 31. The rule sets corporate average fuel economy (CAFE) and CO2 emissions standards for model year (MY) 2021-2026 passenger cars and light trucks. Representatives of the ethanol industry have criticized the rule for failing to provide a pathway to transition to high-octane, low-carbon fuels.
