26 States Challenge Biden Administration's New Fuel Economy Rules

Republican attorneys general argue the mandates will force a costly shift to electric vehicles, impacting consumers and energy security.

The National Highway Traffic Safety Administration's rule requires an average fuel economy of 50.4 mpg by 2031.
Republican-led states claim the rule exceeds the agency’s authority and is legally flawed.
Industry groups, including the American Petroleum Institute, have joined the legal challenge.
Critics argue the rule will increase vehicle costs and strain the electric grid.
The Biden administration defends the rule, citing benefits of reduced pollution and fuel savings.
