The average fuel-economy (window-sticker) value of new vehicles sold in the US in August reached a new record high of 24.9 mpg (9.45 l/100 km), according to the latest monthly analysis from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute. This value is up 0.1 mpg from July and up 4.8 mpg since October 2007 (the first month of their monitoring).
The average sales-weighted fuel economy was calculated from the monthly sales of individual models of light-duty vehicles (cars, SUVs, vans, and pickup trucks) and the combined city/highway fuel-economy ratings published in the EPA Fuel Economy Guide (i.e., the adjusted, window sticker ratings) for the respective models.
The average fuel economy of model year 2013 vehicles sold thus far (October 2012 through August 2013) is 24.7 mpg (9.52 l/100 km). This is up 1.2 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 0.81 in June (the lower the value the better). This value indicates an improvement of 19% 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).
