U.S.: Average mpg of New Cars Falls For the Third Straight Month image

A study made by the University of Michigan shows that the average fuel economy of new vehicles sold in the States in June dropped for the third straight month.

The university’s Transportation Research Institute showed that the average fuel economy for the cars sold last month was 23.6 mpg, down from 23.7 in May and 23.9 in April. The institute began its research in October 2007 and since then fuel economy has increased 17%. At the beginning of 2012 the average fuel economy was 23.6% and it reached a record 24.1% in March, but then started to decrease.

Analysts believe that the decline was due to the tumbling gasoline prices. An AAA report shows that gasoline prices have dropped since April from about $3.92 per gallon to $3.38 per gallon today.

Besides the report about the fuel economy, Sivak and Schoettle released their monthly update of their national Eco-Driving Index, which shows the average monthly emissions generated by each driver in the US, taking into consideration both the distance driven and the vehicle fuel economy. In April the EDI was 0.81, down from 0.83 in March. The lower the value, the better. The study also shows that emissions of greenhouse gases per each newly purchased vehicle are down 19%.
