The Obama Administration’s aggressive fuel economy standards appear to be paying off. A multi-year study from the University of Michigan Transportation Research Institute finds that the average sales-weighted fuel-economy rating of purchased new vehicles in August 2013 reached 24.9 miles per gallon, which is nearly five miles per gallon more than when researchers began collecting data in October 2007.

Model year 2013 vehicles increased 1.2 mpg over model year 2012 vehicles, which marks the biggest yearly increase since tracking began.

To reach their figures, U of M researchers Michael Sivak and Brandon Schoettle calculated the monthly sales of individual vehicles and the combined city-highway fuel economy ratings from the EPA Fuel Economy Guide for each model.

The university has also been tracking greenhouse gas emissions from new vehicles since October 2007 through the national Eco Driving Index. Greenhouse gas emissions from new vehicles has improved 19 percent with an index score down to 0.81 from a base score of 1.

Albeit impressive, these numbers could improve even more thanks to finalized new standards approved by the Obama Administration one year ago that will increase fuel economy for cars and light-duty trucks to 54.5 mpg by 2025.
