Vehicle fuel economy in the US unchanged in November

ANN ARBOR—Gas mileage of new vehicles sold in the U.S. remained the same last month, say researchers at the University of Michigan Transportation Research Institute.

The average fuel economy (window-sticker value) of new vehicles sold in November was 24.9 mpg—unchanged from the revised value for October.

Overall, fuel economy is down 0.6 mpg from the revised peak of 25.5 mpg reached in August of 2014, but still up by 4.8 mpg since October 2007—the first full month of monitoring by Michael Sivak and Brandon Schoettle.

In addition to average fuel economy, Sivak and Schoettle issued a monthly update of their national Eco-Driving Index, which estimates the average monthly emissions generated by an individual U.S. driver. The EDI takes into account both the fuel used per distance driven and the amount of driving—the latter relying on data that are published with a two-month lag.

During September, the EDI fell to 0.83 (the lower the value, the better) from the revised mark of 0.82 in August. The index currently shows emissions of greenhouse gases per driver of newly purchased vehicles are down 17 percent, overall, since October 2007—but 4 percentage points higher than the record low reached in November 2015.
