UMTRI: new vehicle fuel economy hits record high of 25.8 mpg in August

The average fuel economy (window-sticker value) of new vehicles sold in the US in August was at a record high of 25.8 mpg (9.1 l/100 km)—up 0.2 mpg from the value in July, according to the latest monthly report from Dr. Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI).

Vehicle fuel economy is up 5.7 mpg since their first month of monitoring in October 2007


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 0.78 in June (the lower the value the better).

This value indicates that the average new-vehicle driver produced 22% lower emissions in June than in October 2007. 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).




This is good news but at that slow rate (0.81%/year) it will take another 36 years or 2050 to reach 54 mpg.

The percentage of improved much lighter ICEVs, FCEVs, HEVs, PHEVs and BEVs may have to be increased at a much faster rate.
