UMTRI: average new vehicle fuel economy in US unchanged in July from June
04 August 2015
The average fuel economy (window-sticker value) of new vehicles sold in the US in July was 25.4 mpg (9.25 l/100 km)—unchanged from that in June, consistent with the increased market share of vehicle in the middle of the fuel-economy spectrum (such as crossovers), according to the latest monthly report from Dr. Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI).
Fuel economy is down 0.4 mpg from the peak reached in August 2014, but 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 0.82 in May, down from 0.85 in April (the lower the value the better).
This value indicates that the average new-vehicle driver produced 18% lower emissions in May 2015 than in October 2007, but 4% higher emissions 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).
