    Mazda Sets 30% Increase Fuel Economy Target For Next-Gen SkyActiv

      Mazda has big plans for their SkyActiv powertrains.

    Mazda's SkyActiv powertrains are showing what innovations can do to the good-ole' internal combustion engine. But that doesn't mean the automaker isn't resting on its laurels. Far from it. Automotive News reports that Mazda has some big plans in store for the next two-generations of SkyActiv.

    First up is SkyActiv 2. Mazda has set an ambitious goal of increasing fuel economy by 30 percent. To pull this off, engineers will increase the compression ratio from 14:1 to 18:1. SkyActiv 2 will also employ homogeneous charge compression ignition (HCCI) which uses high compression and temperature to ignite fuel for combustion. Now implementing HCCI does bring forth a set of challenges such as engine cooling and the range of engine speeds for HCCI to operate properly. If Mazda can figure out those issues, the engine will likely go into vehicles before 2020. 2020 is an important year since new European regulations which will cut carbon dioxide emissions standards to 95 grams per kilometer.

    Then there is SkyActiv 3, which is aiming to have the same well-to-wheels carbon emissions as electric vehicles. Mazda will look into ways of reducing losses from exhaust and cooling to help get more energy to the wheels.

    Wonder how much loss of actual performance / engine capability to meet this big increase number. Will be interesting to watch.

    probably none... the goal is to to keep the performance the same but get 30% better mpgs. Just reducing the performance of the engine is cheating.
