Mazda3 Skyactiv-CNG Concept
Last week, Mazda CEO Masamichi Kogai said that the company had no plans for a production Wankel rotary anytime in the near future, though the company most identified with the engine that goes "hmmmm" will continue to do research on rotaries. Now, at the Tokyo Motor Show, Mazda is showing that its future powertrain plans include diesel, natural gas and hybrid drives.
The Mazda3 SKYACTIV-CNG Concept is a dual fuel vehicle that has tanks for both gasoline and compressed natural gas. It used a modified version of Mazda's 2.0 liter four that's currently available in the Mazda3. The Mazda3 is sold as the Axela in Japan and the company is also introducing the Axela SKYACTIV-HYBRID. The 2.0 L four cylinder hand has had the compression ration increased to a whopping 14.0:1 and it and a 84 HP electric motor drive the front wheels through an electronically controled CVT.
Like the Toyota Prius it used NiMH batteries and like the Prius it has a total of 134 HP. Fuel efficiency based on Japan's JC08 standard is rated at 72.4 MPG. Finally, Mazda is announcing that the SKYACTIV-D 2.2 clean diesel engine, soon to be available in the U.S. in the Mazda, will be offered in Japanese domestic market versions of the CX-5 and the Mazda3. It will be interesting to see what kind of torque-steer the Mazda3 can develop with 310 lb-ft of twist.
