The average fuel-economy (window-sticker) value of new vehicles sold in the US in January reached a record of 24.5 mpg (6.47 l/100km), according to the monthly tally by Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI).
The figure represents an increase of 0.4 mpg from the revised December value and is up 4.4 mpg (or 22%) from the value in October 2007 (the first month of monitoring). The recent improvements reflect the improved fuel economy of the 2013 model year vehicles.
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 0.82 in November. 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).
