The average fuel-economy (window-sticker) value of new vehicles sold in the US in May was 24.8 mpg (9.49 l/100 km), according to the latest report from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI). This value is unchanged from the revised value for April, and it is up 4.7 mpg since October 2007 (the first month of the 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—stood at 0.81 in March (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).
