U.S. fuel economy near record high
As we reported early last June, new vehicle fuel economy (window-sticker value) in the U.S. hit an all-time high in May of 25.7 miles per gallon (MPG) as reported by the University of Michigan Transportation Research Institute. June saw a slight dip in fuel economy, off 0.2 to 25.5 MPG.
The institute just released their research for July, showing a modest rebound from June of 0.1 MPG with an average fuel economy of 25.6 MPG, just 0.1 MPG of the record high set in May.
Overall, new vehicle fuel efficiency is up 5.5 MPG since October of 2007, when the Institute first started monitoring and collecting data.
The University of Michigan Eco-Driving Index (EDI) estimates average monthly greenhouse gas emissions from an individual U.S. driver. The lower the index value the better. The EDI consists of fuel economy data and miles driven, the later of which is published with a two-month lag time.
The latest EDI for May indicates the average new car driver in the United States produced 21 percent fewer greenhouse gas emissions in May of 2014 than in October of 2007.
