Mazda's 28.1 mpg led all major automakers in average fuel economy for the 2013 model year, according to a new EPA report on industrywide fuel economy. Fiat Chrysler Automobiles' 20.9 mpg, meanwhile, trailed the 11 automakers surveyed. The 148-page report notes that all major automakers except sixth-place Toyota and ninth-place Ford saw their averages increase between 2012 and 2013, and the industry's overall 24.1 mpg is the highest average since the EPA began tracking the data in 1975.
Preliminary 2014 model-year data shows Mazda still in the lead, with 28.8 mpg. That beats Honda (27.6 mpg), Subaru (27.5 mpg), Nissan (26.8 mpg), Volkswagen (26.7 mpg), Toyota (25.8 mpg), BMW (26.0 mpg), Daimler (22.8 mpg), Ford (23.4 mpg), GM (22.0 mpg) and FCA (21.1). The overall 24.1 mpg incorporates corrected mileage from Hyundai-Kia, but the EPA didn't include the Korean automaker in its rankings because Hyundai-Kia is under a continuing investigation for the mileage corrections it issued in late 2012.
