The average fuel economy (window-sticker value) of new vehicles sold in the US in August was 23.8 mpg (9.88 l/100km)—up 0.2 mpg from July, and up 3.7 mpg (or 18%) from October 2007, according to researchers at the University of Michigan Transportation Research Institute (UMTRI). The improvement from July to August most likely reflects the increased price of gasoline, they suggested.
The University of Michigan Eco-Driving Index (EDI)—an index that estimates the average monthly emissions generated by an individual US driver—stood at 0.82 in June (unchanged from May but an improvement of 18% 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).
