The average fuel economy of new vehicles sold in the U.S. in November was 25 mpg — down 0.1 mpg from October, according to Brandon Schoettle and Michael Sivak, researchers from the University of Michigan's Transportation Research Institute (UMTRI).
The value for November is up 4.9 mpg since October 2007, the first month of monitoring, according to the UMTRI report. The value is down 0.5 mpg from the peak of 25.5 mpg reached in August 2014.
The University of Michigan Eco-Driving Index (EDI) — an index that estimates the average monthly emissions of greenhouse gases generated by an individual U.S. driver — worsened to 0.83 in September 2017, up from 0.82 in August (the lower the value, the better).
The EDI indicates that the average new-vehicle driver produced 17% lower emissions in September 2017 than in October 2007, but 5% higher emissions than the record low reached in November 2013.
