Fuel economy up 23 percent since 2007

Dec 06, 2013

Gas mileage of new vehicles sold in the U.S. was 24.8 mpg in November, up 0.1 mpg from the revised October figure, say researchers at the University of Michigan Transportation Research Institute.

Average fuel economy (window-sticker values) of cars, , vans and SUVs purchased last month is up 23 percent, or 4.7 mpg, since October 2007, the first month of monitoring, according to UMTRI researchers 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.

For the third straight month, the EDI tied its best mark at 0.80 (the lower the value, the better) during September, the sixth time that it has registered that low in the past two years. The index currently shows that emissions of per driver of newly purchased vehicles are down 20 percent, overall, since October 2007.
