Next-Gen Mazda2 Will Return 70 MPG, Without An Electric Motor

Follow Viknesh

The U.S. is just getting its first taste of the funky Mazda2, a car that has helped rewrite the rulebook on affordable hatchbacks by showing that cheap doesn’t have to mean drab and boring to drive. However, the next-generation of Mazda’s global small car is currently in the works and is set for debut in Japan as early as the first half of next year.

There’s no word on when this version of the Mazda2 will finally reach the U.S. but when it does we can reveal that it will return a fuel economy of 70 mpg--without the aid of any electric motors. This is because the car will feature Mazda’s next-generation of drivetrain, body and chassis technologies, dubbed SKYACTIV.

It will come powered by a SKYACTIV-G engine, Mazda's next-generation direct injection gasoline mill that achieves significantly improved fuel efficiency thanks to a high compression ratio of 14.0:1 (the world’s highest for a production gasoline engine). In addition to the improved fuel economy, Mazda also claims that the higher compression ratio enables more torque, especially at lower to mid-range engine speeds, which should make the car a whole lot more fun to drive around the town.

Also aiding fuel economy will be a new-generation of automatic and manual transmissions. Mazda claims that its new SKYACTIV-Drive automatic transmission leads to a 4-7 percent improvement in fuel economy thanks to improved torque transfer efficiency through a wider lock-up range. A new manual transmission has also been developed, one that features significantly reduced size and weight and reduced internal friction.

Finally, a lighter body design will also help improve the fuel economy of the next-generation Mazda2 even further. The automaker’s new SKYACTIV-Body is claimed to be 8 percent lighter yet 30 percent more rigid than current designs. These gains are mostly achieved through optimized bonding methods and expanded use of high-tensile steel.

The end result of all the advanced technology is a car that Mazda claims will return 70 mpg, making it the world’s most fuel efficient production gasoline car. The only question that remains: How long will it take Mazda take to bring this model over to the U.S.?

  1. Shouldnt be to hard, the V6 camaro has a DI motor making 300hp and gets 30mpg. Make a 4 cylinder that has about 120hp, put it in a small light car and real life 45-55mpg should be doable. Use a smaller version of that (80hp) in a hybrid and maybe hit 65-75mpg.

  2. The quoted 70mpg are referred to the Japanese Cycle where, for example, a Prius get 89mpg.
    Please get your numbers right.

  4. 70mpg is great, but...what's the horsepower and torque? There are a ton of scooters outside my apartment that get 70mpg.

  5. Press releases about future performance are a dime a dozen. Call me when a car that actually gets 70 mpg arrives. Not to mention, a hybrid version of this might get even more amazing mileage.

  8. We need a law approved by congress to eliminate the requirement for smog devices like catalytic converters if a car already has low emissions. Smog devices reduce gas mileage, and several cars in Europe produce almost no emissions without the USA added devices, yet if brought into USA are required to put on catalytic converters. Crazy!

  9. Is this the American gallon or the British gallon. If it is the American gallon I make this 3.4 litres/100km. If it is the British gallon I make it 4.0litres/100km.
    What is the policy of Green Car Reports on quoting mpg??

  10. Is this going to be another Chevy Sprint (http://www.popularmechanics.com/cars/news/fuel-economy/epa-fuel-efficient-cars-chevy-sprint) without the power to get out of its own way?

  11. Hmm 28city, 34MPG highway for the 2014 Mazda 2 with a 100HP 1.5L engine! Less than half of 70MPG!
