Mazda has received a tremendous amount of public and industry praise in the last few years, following up the successful introduction of its Skyactiv technology (powertrain and otherwise), with strong products like CX-5, Mazda6 and most recently, the Mazda3. At the Tokyo Motor Show, Mazda has taken yet another step forward with Skyactiv and the 3, showing the compact (called "Axela" in Japan) with an all-new compressed natural gas engine in the Skyactiv-CNG Concept.
Mazda thinks that CNG-powered vehicles are due for an uptick in demand,
and the company believes this new powertrain will add valuable breadth
to the Mazda3 range. The CNG Concept is actually a duel-fuel vehicle,
capable of running on either natural gas or gasoline. In fact, we're
told that the high compression ratio (14:1) inherent in
Skyactiv-technology gasoline engines makes conversion to CNG
Perhaps more interesting is the unveiling of Mazda's first-ever hybrid
powertrain, aptly named Skyactiv-Hybrid. The new system, which is only
slated for the Japanese market at this point, connects an electric motor
to a 2.0-liter four-cylinder gas engine, using it to assist at low
engine speeds and under low-load conditions. The electric motor is
supplied by a nickel-metal hydride battery of unstated capacity.
The end result of the Skyactiv-Hybrid in the Mazda3 is fuel consumption
estimated at 3.2 liters per 1,000 kilometers on the lenient Japanese
cycle, or something like 74 miles per gallon, and total system output of
around 134 horsepower (136 PS).
