A new report from The University of Michigan Eco-Driving Index:
The average fuel economy (window-sticker value) of new vehicles sold in the U.S. in September was 23.8 mpg – unchanged from August, but up 3.7 mpg (or 18%) from October 2007 (the first month of our monitoring).

The University of Michigan Eco-Driving Index (EDI)–an index that estimates the average monthly emissions of greenhouse gases generated by an individual U.S. driver – stood at 0.80 in July. This value indicates a record improvement of 20% since October 2007. 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).
