UMTRI: average new car fuel economy in June drops from May; April EDI up
06 July 2015
The average fuel economy (window-sticker value) of new vehicles sold in the US in June was 25.4 mpg—down 0.1 mpg from May, according to the monthly report from Dr. Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI). They suggested the decline likely reflects the increased sales of light trucks and SUVs in June.

Fuel economy is down 0.4 mpg from the peak reached in August 2014. However, vehicle fuel economy is up 5.3 mpg since October 2007 (the first month of their monitoring).
The University of Michigan Eco-Driving Index (EDI)—an index that estimates the average monthly emissions of greenhouse gases generated by an individual US driver—was 0.85 in April, up from 0.82 in March (the lower the value the better). This value indicates that the average new-vehicle driver produced 15% lower emissions in April 2015 than in October 2007, but 9% higher than the record low reached in August 2014.
The EDI takes into account both vehicle fuel economy and distance driven (the latter relying on data that are published with a two-month lag).
