The average fuel economy of new cars sold in the U.S. last month dropped to 24.6 MPG, down 0.3 MPG from August.

The average sales-weighted fuel economy was calculated by University of Michigan Transportation Research Institute’s researchers Michael Sivak and Brandon Shoettle, which has been monitoring the data since October 2007. The value is calculated from the monthly sales of individual models of light-duty vehicles and the combined city/highway fuel-economy ratings published in the EPA Fuel Economy Guide.

August was an all-time high of 24.9 MPG and the slight decrease in September is mostly caused by the continuing drop of gasoline prices. On the whole, fuel economy is up 4.5 MPG compared to when data was first collected in October 2007. As for the average fuel economy of model year 2013 vehicles, that’s at 24.7 MPG, which is an increase of 1.2 MPG compared to 2012 model year vehicles.
