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.

That’s a reduction from 2.85 gal per 100 miles down to 2.22 or a 22% reduction in fuel consumption.

The standards will also require heavy-duty pickup trucks, such as the Chevrolet Silverado 2500 HD, and large vans, such as Amazon delivery vans, to reach 35 miles per gallon by 2035, up from 18.8 miles per gallon today.

That’s a change of about 5.3 gal per 100 mi to 2.9 gal, or a 45% reduction in fuel consumption.

A Toyota Highlander Hybrid currently gets 35 mpg. To do over 20% less fuel it would need to be super aerodynamic, and lose about a ton of mass. Or it would have to be fully electric - the Rivian R1S gets 70 mpg equivalent.
