The University of Michigan’s Transportation Research Institute said that fuel economy of vehicles in the United States dropped in 2015, compared to 2014.
According to the Institute, the average fuel economy of new vehicles last year fell to 25.3 miles per gallon (mpg), down 0.1 from the value for the vehicles sold in 2014.
In December last year, fuel economy was 24.9 mpg, compared to 25.0 mpg in December 2014, while representing a 0.2 decrease from 25.1 mpg in November 2015.
Fuel economy reached 25.8 mpg August 2014.
“This decline likely reflects the continuing drop in the price of gasoline in December, and the consequent increased sales of pickup trucks, SUVs and crossovers,” UMTRI’s Michael Sivak said in a statement.
As we reported previously, AAA expects no increase in gas prices in 2016, and the average price of a gallon of regular gasoline would stay between $2.25 and $2.45 a gallon. Last year, the average gasoline price was $2.40 per gallon, which allowed Americans save $540 on gas. AAA estimates that gas will continue to be cheaper for much of 2016. According to an analysis, the average gas prices is expected to go above $3 a gallon this year.
Sivak and colleague Brandon Schoettle also issued a monthly update of their national Eco-Driving Index (EDI), which estimates the average monthly emissions generated by an individual U.S. driver.
“The EDI takes into account both the fuel used per distance driven and the amount of driving—the latter relying on data that are published with a two-month lag.”
During October, the EDI rose to 0.84 from 0.83 in September. The index currently shows emissions of greenhouse gases per driver of newly purchased vehicles are down 16%, overall, since October 2007—but 6% higher than the record low reached in August 2014.
