Lawsuit Filed Against NHTSA's 2027-2032 CAFE Standards

The American Petroleum Institute (API) filed a case against the National Highway Traffic Safety Administration (NHTSA) in the Fifth Circuit Court of Appeals. This lawsuit challenges the newly established Corporate Average Fuel Economy (CAFE) standards for passenger cars and light-duty trucks for model years 2027-2032.

These stringent standards are designed to phase out vehicles powered by liquid fuels, limiting consumer choices and raising vehicle costs amid persistent inflation. API's filing is the third in a series of lawsuits, and it has also contested recent vehicle regulations by the Environmental Protection Agency (EPA).

The rule mandates an increase in fuel economy to 66.4 miles per gallon (MPG) for passenger cars and 46.2 MPG for light trucks by 2032, compared to the current standard of 40.6 MPG by 2024. CIPA also believes such standards are unrealistic and exceed the agency's regulatory authority, potentially jeopardizing the agriculture and energy sectors.
