The average fuel economy of new vehicles sold in June dropped slightly to 25.3 mpg.
Calculated from the monthly sales of individual models of light-duty vehicles, which includes cars, SUVs, vans and pickup trucks, the average sales-weighted fuel economy saw an increase from 25.1 mpg in April to 25.4 mpg in May. But as we head into summer, fuel economy has dropped 0.1 mpg with an increased market share of pickup trucks and SUVs. The data comes from University of Michigan Transportation Research Institute’s Michael Sivak and Brandon Schoettle, who have been monitoring the data since October 2007.
The average sales-weighted fuel economy hit an all-time high of 25.8 in August 2014 but is still up 5.2 mpg since the two began monitoring data.
