Automakers selling cars in the United States now have even less incentive to care about fuel economy. As Ars has noted before, the current administration and its Republican allies in Congress have been working hard to undermine federal regulations meant to make our vehicle fleet more efficient.
Some measures have been aimed at decreasing adoption of electric vehicles—for example the IRS clean vehicle tax credit will be eliminated at the end of September. Others have targeted federal fuel economy regulations that require automakers to meet specific fleet efficiency averages or face punishing fines for polluting too much. At least, they used to.
According to a letter seen by Reuters, sent to automakers by the National Highway Traffic Safety Administration, the federal government has decided it will not levy any fines on companies that have exceeded the corporate average fuel economy limits dating back to model year 2022.
