UMTRI: average fuel economy of new light-duty vehicles sold in November up slightly from October

4 December 2013

The average fuel-economy (EPA window-sticker) value of new light-duty vehicles sold in the US in November was 24.8 mpg, up 0.1 mpg from the revised October value, according to the monthly report from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute. Vehicle fuel economy is up 4.7 mpg or 23% since October 2007 (the first month of their 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 0.80 in September (the lower the value the better). This value indicates an improvement of 20% 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).

Is the sticker data reliable. Many manufacturers claim 10+% better mpg than users normally do.

In other words, the 24.8 mpg claimed may be under (248 x.9)= 22.3 mpg, with brand new Nov 2013 cars.

The current fleet mpg is still under 18 mpg and closer to 15 mpg for most. .
