UMTRI: average US new vehicle fuel economy drops in September

The average fuel economy (window-sticker value) of new vehicles sold in the US in September was 25.2 mpg (9.33 l/100 km), down 0.1 mpg from August, according to the latest monthly report from Dr. Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI). This decline likely reflects the decreased price of gasoline in September, and the consequent increased sales of pickup trucks, SUVs, and crossovers, they suggested.

Fuel economy is down 0.6 mpg from the peak reached in August 2014, but up 5.1 mpg 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—was 0.82 in July, unchanged from June (the lower the value the better). This value indicates that the average new-vehicle driver produced 18% lower emissions in July 2015 than in October 2007, but 4% higher emissions than the record low reached in August 2014.

The EDI takes into account both vehicle fuel economy and distance driven (the latter relying on data that are published with a two-month lag)




Have more jobs and $$$, will travel more in larger gas guzzling vehicles?

@ HarveyD: This is typical of upturns in the housing market.

Contractors are buying trucks to build houses and consumers are buying SUVs to cart their kids around.


If so, it seems obvious that e-carts are required to move kids around and e-trucks for construction workers and materials?
