Mazda has announced plans to show a CNG version of the all-new Mazda3 next month at the Tokyo Motor Show.

Approximately two weeks ago Mazda revealed a hybrid version of the Axela/Mazda3 Hybrid and now they are previewing a CNG concept Mazda3 which will be showcased towards the end of November at the Tokyo Motor Show. The concept will feature a dual fuel system so it will be able to run not only on gasoline but also on compressed natural gas.

Mazda says only minor modifications were necessary for the conversion since the firm's SKYACTIV-G gasoline engine already has a high compression ratio which is necessary since CNG engines burn fuel at a higher pressure. The Japanese marque mentions CO2 emissions should drop by 20 percent compared to the regular gasoline-powered Mazda3 which can be had in hatchback and sedan body styles.

Mazda hasn't said a word about putting the CNG version on sale sometime in the future but it's likely to happen since the company acknowledges demand for CNG-powered cars has risen over recent years.
