The Environmental Protection Agency released their annual report on industrywide fuel economy this week and says that 2013 model year vehicles achieved an average of 24.1 miles per gallon — up 0.5 mpg from the previous year and almost 5 mpg since 2004.
"We are thrilled to see that manufacturers continue to innovate and are bringing technologies to improve fuel economy online even faster than anticipated," said EPA Administrator Gina McCarthy.
Mazda was the top automaker in the report with a fleet average of 28.1 MPG, while Nissan was the leader in the full-line automakers with 26.8 MPG. The Detroit automakers made up the bottom with Ford at 22.2 MPG, GM at 22.0 MPG, and Fiat Chrysler at 20.2 MPG.
The EPA also notes in its report more fuel saving technologies are beginning to appear on vehicles. For example, the report notes that five percent of vehicles that aren't hybrids. This up from none back in 2009.
