US Vehicle fuel economy up for the first time since March  

Posted by Big Gav in

PhysOrg has an interesting graphic showing vehicle fuel efficiency in the US - Vehicle fuel economy up for the first time since March.

Average fuel economy (window-sticker values) of cars, light trucks, minivans and SUVs purchased in August was 23.8 mpg, the fourth-best month on record and an 18 percent increase (3.7 mpg) from October 2007, the first month of monitoring by UMTRI researchers Michael Sivak and Brandon Schoettle. The improvement from July to August—0.2 mpg—most likely reflects the increased price of gasoline, they say.

In addition to average fuel economy, Sivak and Schoettle issued their monthly update of their national Eco-Driving Index, which estimates the average monthly emissions generated by an individual U.S. driver. 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.
