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.
We (Canadians) use L/100km more often.
A hybrid sedan might get 3 to 4 L/100km in ideal Canadian conditions using a lot more of the battery, closer to 5 in winter.
Your normal sedan ranges from 5 to 8. (40MPG = 7 L/100km)
An SUV ranges from 8 to 13. (25MPG = 10.9L/100km)
A pick up truck will be from 9 to 16 L/100km. (20MPG = 13.9L/100km)
