UMTRI: average fuel-economy of new vehicles in the US in October rose to 24.8 mpg

The average fuel-economy (window-sticker) value of new vehicles sold in the US in October was 24.8 mpg (9.49 l/100km), up 0.2 mpg from September, according to the monthly analysis from Michael Sivak and Brendan Schoettle from the University of Michigan Transportation Research Institute (UMTRI). Vehicle fuel economy is up 4.7 mpg since October 2007 (the first month of their monitoring).

They observed that the results reflects the net effect of two opposing trends: the improved fuel economy of model year 2014 vehicles, and the decreased demand for fuel-efficient vehicles because of the recent reduction in the price of gasoline.

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 August (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).

24.8 mpg sucks. New car fleet should average at least 35 mpg and we really ought to be at 50 mpg today.


It's good to hear that fuel economy is increasing in US. It is interesting to know though that this is caused by two very opposing trends. I have been doing research recently on fuel economy specifically for our truckers out there. In one of my articles, I have covered the subject on improving fuel economy through proper tire use.
