Mazda is reportedly working to innovate the traditional hybrid system by developing a new diesel-based powertrain.
Not much is known, though The Japan News reports Mazda’s diesel-hybrid system is destined for Asia and Europe only and could be available as early as 2016 in the Mazda3, also known as the Axela in Japan. Thanks to the use of a diesel motor, the new hybrid system could increase fuel economy by up to 30 percent, offering the equivalent if 94 mpg.
In Japan, the Mazda3 can be had in gasoline hybrid form with a SKIACTIV-G 2.0L four-banger with an electric motor and a CVT transmission. The going mpg rate for that model is the equivalent to 73.5 mpg.
