New vehicle fuel economy increased in March, research shows

Gas mileage highest since July


ANN ARBOR, Mich. – The fuel economy of new vehicles increased in March, according to researchers at the University of Michigan Transportation Research Institute.

The average fuel economy of new vehicles sold last month was 25.2 mpg, compared to 25.1 in February. 

According to researchers, the gas mileage was the highest since last July but the same as three years ago.

The peak for fuel economy was 25.5 mpg in August 2014. The first full month monitored by researchers Michael Sivak and Brandon Schoettle was October 2016. At that time, the fuel economy was 20.1 mpg.

The researchers also monitor emissions generated by drivers.

The Eco-Driving Index takes into account fuel used per distance driven and the amount of driving to determine the average monthly emissions by an individual U.S. driver.

Researchers found that the EDI increased to 0.84 in January, the highest number since April 2016.

They also found that emissions of greenhouse gases from newly purchased vehicles are down 16 percent overall in comparison to October 2007. However, the amount is 6 percent higher than the record low of 0.78 in November 2013.
