UMTRI: November average new vehicle fuel economy in US same as October; September Eco-Driving Index at a record 0.8

The average fuel economy (window-sticker value) of new vehicles sold in the US in November was 24.1 mpg (9.76 l/100 km)—tying the record set in October, and up 4.0 mpg from October 2007, according to the latest tracking figures from Michael Sivak and Brandon Schoettle at the University of Michigan Transportation Research Institute (UMTRI).

This 20% improvement in fuel economy (mpg) corresponds to a 17% reduction in fuel consumption (gallons per mile).

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. This value indicates a record improvement of 20% since 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).

Can we assume that pick-ups and other similar utility vehicles were excluded from this survey?

At 0.8 gal/year fuel consumption reduction rate, USA's average will reach about 27.5 mpg in 2017, 31.5 mpg in 2021, 35.5 mpg in 2025?

The rate of change could accelerate when more HEVs, PHEVs and BEVs and more efficient ICEVs hit the roads.
