CHICAGO, Oct. 6 (Xinhua) -- The average fuel economy of new vehicles sold in the U.S. in September remained unchanged at 25.3 mpg, say researchers at the University of Michigan Transportation Research Institute (UMTRI).

Overall, fuel economy is up by 5.2 mpg since October 2007, the first full month of monitoring by UMTRI researchers Michael Sivak and Brandon Schoettle, but still down 0.2 mpg from the peak of 25.5 mpg reached in August 2014.

For model year 2017 vehicles sold from October 2016 to September 2017, the average fuel economy was 25.2 mpg, up slightly from 25.1 mpg for each of the preceding three model years.

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 relies on data that are published with a two-month lag.

The EDI improved to 0.81 in July, down from 0.83 the month before. The index currently shows emissions of greenhouse gases per driver of newly purchased vehicles are down by 19 percent since October 2007.
