Biden Administration Tightens Mileage Standards to Buoy E.V.s | The new rule requires automakers to achieve an average of 65 miles per gallon across all models by 2031.

Yes it's a little ridiculous. At least the "light truck" mpg requirement is getting increased too, though not as much as the car one:

The new standards require American automakers to increase fuel economy so that, across their product lines, their passenger cars would average 65 miles per gallon by 2031, up from 48.7 miles today. The average mileage for light trucks, including pickup trucks and sport utility vehicles, would have to reach 45 miles per gallon, up from 35.1 miles per gallon.
