New-Vehicle MPG Remains Unchanged from January
The average fuel economy for new vehicles sold in February was 25.2 mpg — unchanged from the value that was revised for January, according to the University of Michigan's Transportation Research Institute (UMTRI).
Fuel economy is down 0.6 mpg from the peak reached in August of 2014, but remains 5.1 mpg higher than October of 2007, when UMTRI began tracking the data, according to UMTRI researchers Michael Sivak and Brandon Schoettle.
The University of Michigan Eco-Driving Index — an index that estimates the average monthly emissions of greenhouse gases generated by an individual U.S. driver — was 0.85 in December of 2015, which is 0.03 higher than the value for November of 2015.
This value indicates that the average new-vehicle driver produced 15% lower emissions in December of 2015 than in October of 2007, but 7% higher emissions than the record low reached in August of 2014.
