The average fuel economy of new light vehicles sold in the U.S. in February remained unchanged from January at 25.1 mpg, the University of Michigan Transportation Research Institute said in a report this week.
The research, conducted by Michael Sivak and Brandon Schoettle, found that average fuel economy figures for new light vehicles sold in the U.S. have increased by 5 mpg since October 2007, when the study began.
The average fuel economy of new cars and light trucks -- as reflected in EPA ratings on window stickers -- is down from February 2016, when figures for the month hit a high of 25.2 mpg. The fuel economy value for February is also 0.4 mpg lower than the August 2014 peak of 25.5 mpg.
In a separate study, the institute said its greenhouse gas emissions index for U.S. drivers also was unchanged from November to December at 0.83. That value means the average new-vehicle driver generated 17 percent fewer emissions in December than in October 2007, when the institute began to track the data.
Year-over-year U.S. light-vehicle sales slid 1.1 percent in February, with car deliveries dropping 13 percent and truck volume rising 7 percent. Pickup and crossover demand drove gains across the truck segment, with a nearly 10 percent rise in pickup and crossover sales last month.
While U.S. truck sales continue to grow, they haven’t drastically reduced fuel efficiency ratings of light vehicles. That’s because the fuel efficiency of light trucks continues to increase over time, reducing fuel consumption, Consumers Union, a division of Consumer Reports, reported.
