epa mazda holds highest mpg lowest co2 averages for 2013

Mazda’s green vibes must just feel right with the Environmental Protection Agency, as the agency has proclaimed the automaker has the highest fuel economy and lowest greenhouse gas emissions of any automaker in 2013.

Edmunds reports Mazda’s portfolio netted an average of 28.1 mpg and 316 grams/mile of CO2, followed by Honda (27.4/324), Subaru (26.7/332) and Nissan (26.2/339). Nissan also had the greatest improvement in both rankings, jumping up 2.2 mpg and cutting down 30 g/mi of CO2 compared to 2012. All four are set to continue their green ways, as well, with Mazda leading the way again for 2014 at 28.8 mpg/309 g/mi CO2.

At the bottom of the list, Fiat Chrysler Automobiles delivered an average of 20.9 mpg/425 g/mi CO2. Volkswagen AG bested the other German manufacturers with 353 g/mi CO2 and 25.7 mpg, while Hyundai and Kia continue to be footnotes due to an ongoing investigation regarding fuel economy numbers.

As stated earlier, the overall average mpg for 2013 came out to 24.1 mpg, while overall CO2 emissions averaged 369 g/mi. The EPA adds that the number of vehicles topping out at 40 mpg and above jumped from three to 26, and that the top three most fuel-efficient models for 2013 are the Chevrolet Spark (119 combined MPGe), Honda Fit EV (118) and Fiat 500e (116).

    Highest MPG, lowest CO2? Aren't those *the same thing* in this context? It's like saying "the sky is blue, and also the complement of orange".

      If an automaker has diesels or other fuel sources, then CO2 calcs may change.

    More and more in recent years Mazda inhabits the space that Honda once did. Vehicles with sporty driving, efficient, and cutting edge powertrains.

      >>More and more in recent years Mazda inhabits the space that Honda once did. I've noticed that too. In addition, Mazda continues to offer a hatch. Old Honda/Acura had them on the Integra, RSX, Civic, and Accord. One could argue hatches don't sell, but then the Mazda3, Ford Focus, and VW Golf show there is market for them.

    Highest MPG, loudest road noise of any new cars I've driven. These things are related. I love Mazdas and what they stand for, but until they get the road noise down I can't buy another one.

      @Drzhivago138 I say, mightn't that still be rather noisy were you to pull it with your Shire horse?

    Breaking news! Mazda sells ten cars that get weak gas mileage that is slightly better than a fullsize pickup.
