Researchers at the University of Michigan Transportation Research Institute said that after a three-month drop, the fuel economy for the new cars sold in the States remained the same in July.
For the Light trucks, cars, minivans and SUVs bought in July the average fuel economy was 23.6 mpg, up 17% (3.5 mpg) from October 2007, which was the first month monitored by Michael Sivak and Brandon Schoettle, the researchers from the University of Michigan Transportation Research Institute.
Besides the average fuel economy, the two researchers also released their national Eco-Driving Index monthly update, which shows the average monthly emissions produced by an individual U.S. driver, and takes into consideration both the distance driven and the vehicle’s fuel economy.
In May, the EDI reached 0.82, an increase from 0.81 in April. Since the lower the value, the better, the index clearly shows that emissions of greenhouse gases per driver of the new vehicles has increased in May, but dropped 18% since October 2007.
For July, the unadjusted Corporate Average Fuel Economy performance was 29 mpg, up 17% (4.3 mpg) from October 2007, but the same as in June.
