For the fourth year in a row the U.S. government is giving Mazda the highest marks for saving drivers money on gas.

The most recent Light Duty Fuel Economy Trends report by the U.S. Environmental Protection Agency says Mazda is the most fuel-efficient auto manufacturer in the U.S. The EPA reports Mazdas fleet-wide adjusted fuel economy performance was 29.6 miles per gallon for model year 2015.  That’s the last year the EPA has information for this report. 

Mazda points out they achieved these results without offering a hybrid or electric vehicle in the U.S. They credit their SKYACTIVE Technology. 

The EPA report projects Mazda will do even better for the 2016 model year.  They give the car company a preliminary fleet-wide adjusted fuel economy rating of 30.7 miles per gallon.  However, the EPA will not have final figures for 2016 until next year’s report.
