The average fuel economy for new vehicles sold in the United States in May has remained unchanged since April at 25.3 mpg, according to Michael Sivak and Brandon Schoettle, researchers from the University of Michigan Transportation Research Institute (UMTRI).
The May value is up 5.2 mpg since October 2007, the first month of monitoring by UMTRI. This value is 0.2 mpg below the peak of 25.5 mpg from August 2014.
The University of Michigan Eco-Driving Index, which estimates the average monthly emissions of greenhouse gases generated by a single driver in the U.S., was 0.85 in March 2017, remaining stable since February 2017. A lower value indicates fewer emissions.
The average new-vehicle driver produced 15% lower emissions in March 2017 than October 2007, but 7% higher than the record low value in November 2013.
