The US Department of Transportation finalized a rollback of fuel-economy regulations, reducing General Motors' (GM) compliance costs by $20.4 billion through 2031. Industry-wide savings are estimated at $60.6 billion, with other automakers like Stellantis, Ford, Toyota, and Honda also benefiting. The new rules, set to take effect in December, ease requirements for emissions-reduction equipment and EV production. GM supports the rule's alignment with market realities.
