Fuel Fact of the Week

Fact #1175: Vehicles Registered in the District of Columbia Averaged 22 Miles per Gallon in 2018

Vehicles registered in the District of Columbia (D.C.) had a higher average fuel economy in 2018 than any state. The average fuel economy of vehicles in each state were calculated by researchers at Argonne National Laboratory using vehicle registration and EPA combined city/highway fuel economy data. D.C. and twenty-four states averaged above 20 miles per gallon (mpg) while the rest of the states averaged from 18.1 to 20 mpg.

Question of the Month

How is fuel economy determined and reported for alternative fuel vehicles?

Last month we learned about how the U.S. Environmental Protection Agency (EPA) determines and reports conventional light-duty vehicle fuel economy ratings. While alternative fuel vehicle (AFV) fuel economy testing is largely similar to that of conventional fuels, the EPA makes some adjustments to account for different vehicle technology and fuel energy content. By tailoring AFV fuel economy testing and reporting, the EPA is able to provide apples-to-apples comparisons and allow consumers to make informed decisions.
