U.S. Tightens Car Mileage Rules, Part of Strategy to Fight Climate Change

The new measure requires automakers to achieve an average of 65 miles per gallon for all the car models they sell by 2031.

The new standards require American automakers to increase fuel economy so that, across their product lines, their passenger vehicles 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. Selling electric vehicles and hybrids would help bring up the average mileage per gallon across their product lines.

    I did look into it and yes, it does look like the averaging is done harmonically and not arithmetically. That’s how it cuts the outlier strategy.

    So I guess the theory of gaming the system that hard is not as possible or at least mitigated to an effective degree.

    Still though, even that they’re using harmonic mean doesn’t deviate to far from the reality this regulation was written by industry.
