The average fuel-economy (window-sticker) value of new vehicles sold in the US in June was 24.7 mpg—down 0.1 mpg from May, according to the latest monthly report from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI). This slight reduction likely reflects the recent drop in the price of gasoline, they suggested.
Overall, however, the monthly average fuel economy for new vehicles is up 4.6 mpg since October 2007 (the first month of their monitoring).

The average fuel economy of model year 2013 vehicles sold thus far (October 2012 through June 2013) is 24.6 mpg. This is up 1.1 mpg from model year 2012 vehicles.
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—stood at 0.82 in April (the lower the value the better). This value indicates an improvement of 18% since October 2007. The EDI takes into account both the fuel used per distance driven and the amount of driving (the latter relying on data that are published with a two-month lag).
