Recalculating Electric Vehicle Efficiency for Accuracy and Legitimacy Act of 2024

This bill changes how the U.S. calculates electric vehicle (EV) fuel efficiency for regulatory purposes. It requires the Secretary of Energy to annually review and update "equivalent petroleum-based fuel economy values" for EVs based on factors like battery degradation, grid efficiency, critical mineral usage, and real-world driving patterns (e.g., weather impact and charging habits). These updated values must then be used by the EPA when setting average fuel economy standards for all vehicles, directly affecting EV manufacturers and the federal fuel efficiency program. The changes aim to create more accurate comparisons between EVs and gasoline vehicles for regulatory consistency.
