UMTRI: average US new vehicle fuel economy in September drops

The average fuel-economy (window-sticker) value of new vehicles sold in the US in September was 24.6 mpg (9.56 l/100 km), according to the latest analysis from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute. This value is down 0.3 mpg from August, likely reflecting the recent reduction in the price of gasoline, they suggested.

Despite this drop, vehicle fuel economy is up 4.5 mpg since October 2007 (the first month of their monitoring).

The average fuel economy of model year 2013 vehicles (vehicles sold October 2012 through September 2013) was 24.7 mpg (9.52 l/100 km). This is up 1.2 mpg from model year 2012 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 0.80 in July (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).

With more jobs in USA (except for the next few days due to political R-power play) Americans will buy larger vehicles and fuel economy may go negative for a few months.

A purchase tax based on total vehicle weight and/or liquid fuel consumption + higher gasoline taxes could help?
