EPA Names Mazda Most Fuel-Efficient Automaker


On the heels of the EPA's news that the average fuel-economy of light-duty new vehicles continues to climb, the agency announced that Mazda is leading the charge. It named the Japanese company the most fuel-efficient automaker, with the highest fleetwide adjusted fuel economy of 27.1 mpg for model-year 2012 new vehicles; model-year 2013 figures haven't been finalized yet. 

At the low end are GM and Chrysler, but that's hardly surprising. Mazda's car-heavy lineup features four-cylinder engines; only the CX-9 crossover uses a V-6. GM and Chrysler, by comparison, offer a full suite of V-6 and V-8 trucks and SUVs, lowering their average to 21.7 and 20.1 mpg, respectively.

In second place is Honda with a fleetwide average of 26.6 mpg, followed closely by Toyota at 25.6. What's more impressive is Subaru's ranking of 25.2, notable considering the automaker's across-the-board all-wheel-drive lineup.

Of course the American brands are at the bottom. It's such a shame they can't turn that around! Another win for Mazda; good for them!


Congrats, mazda. The 6 is on my short list among new sedans.


I love Mazdas and congrats. But to be fair the American brands sell a lot of trucks and big SUVs which brings their average down. Mazda doesn't even have a SUV....the CX-5 and CX-9 are CUVs.


True, the American brands do dominate the truck/SUV market. That's been a hot market for a while. I still hope they can get closer to the top some day!

Umm hellooo... Tesla....?


@Bobby - You can't measure fuel effiency in a car that doesn't use fuel.


@Johnny - What is fuel? Fuel is whatever gives energy to run a given item.

Calories = fuel for us.
Electricity = fuel for microwaves, lights, ect.

So Tesla does indeed use fuel and does run out thus has a fuel efficiency number. Might not be MPG but def. does have a numbering system.
