White House Rolls Back Fuel Economy Standards – Stefan Buchholz DOT com

[T]he Trump administration announced less stringent Corporate Average Fuel Economy (CAFE) standards in an effort to bring down the price of new vehicles. The administration says that rules put in place by the Biden administration broke the law by going beyond the requirements mandated by Congress when the CAFE program was started. The new regulations will require automakers to meet an average fuel-economy figure of 34.5 mpg across 2031-model-year vehicles, instead of the 50.4 mpg that would have been required under the previous regulations. This is a much-needed move as they also recently closed a number of loopholes, such as the assumed fuel-savings credit for engine start-stop technology, that made it more difficult to meet these goals. More so, a recent string of engine and transmission failures from multiple manufacturers shows that meeting fleet standards came at a very significant cost of reduced reliability.
