US Government Continues to Target Gas-Powered Cars with New Emission and Mileage Regulations.

The US Energy Department has proposed reducing electric vehicles' (EV) mileage ratings to meet government fuel economy requirements, which could force automakers to sell more low-emissions cars or improve conventional models. The current system has not been updated in more than two decades. Environmental groups petitioned for the change in 2021, arguing that excessively high imputed fuel economy values for EVs means that a relatively small number of EVs will mathematically guarantee compliance without meaningful improvements in the real-world average fuel economy of automakers' overall fleets.
