Mazda3 to showcase CNG, Hybrid versions in Tokyo

Mazda has made huge gains in its competitive set with the introduction of its Skyactiv technologies, and the Japanese automaker appears to have no plans on slowing down. While we're still waiting for the Mazda6 Skyactiv-D diesel to go on sale in the US, Mazda announced that it will debut new Skyactiv-Hybrid and Skyactiv-CNG versions of the Mazda3 (standard US-spec model shown above) at next month's Tokyo Motor Show.
Matching up with what we heard earlier in the summer, the Mazda3 Skyactiv-Hybrid is intended for Japan only, but there are no details about this system regarding fuel economy, electric components or specs. Likewise, there are no details for the Mazda3 Skyactiv-CNG Concept, which is a bi-fuel version of the car running on both gasoline and compressed natural gas. As this car's name suggests, the CNG model is a concept vehicle, and there is no indication that Mazda plans offering such a model here in the US.
In addition to these two vehicles, Mazda will also have an Atenza (Mazda6) on display showing off some vehicle-to-vehicle (V2V) safety systems, called the ASV-5 (Advanced Safety Vehicle). Scroll down for Mazda's official press release.

Mazda's next-gen SkyActiv engines will drop spark plugs in favor of high compression

Homogeneous charge compression ignition, or HCCI, is the black art of internal combustion engines that aims to produce diesel-like fuel efficiency for the cost of gasoline. Although some of its competitors have developed and subsequently given up on the tech, Mazda confirmed that the next-generation of SkyActiv engines will employ HCCI technology, improving fuel economy by 30 percent and at the same time reducing exhaust emissions. According to Nikkei, a new SkyActiv family of engines is set to debut under the hood of the next-gen Mazda3 sometime in 2018 before making its way into other vehicles. In simple terms, an engine that uses HCCI burns the air/fuel mix using pressure instead of with spark plugs, just like a diesel. At 14:1, Mazda's gasoline engines already have some of the highest compression ratios out there, but a move to HCCI means cranking up the compression to 18:1. While the tech sounds relatively straightforward, using HCCI means dealing with a number of side issues. It's one of those "on paper" ideas that compounds problems when put into practice. Heat, revs, and fuel must all be carefully managed as gasoline doesn't burn the same way as diesel. Mazda is mum on details, but the automaker seems confident that the issues have been sorted. If the new engines do indeed make it to market with HCCI, Mazda will have out-engineered GM, Daimler, and Hyundai, all of which have tried and failed to develop HCCI engines in a cost-effective package. With the market moving towards electrification, it's interesting to see Mazda still focusing so heavily on traditional internal combustion gasoline engines. It's an indication of where they see the market heading for the next few years. Although the automaker has been hesitant to move forward with hybrid and electric powertrains, Nikkei also reports that Mazda will begin mass production of EVs in 2019. Related Video:

Mazda plans a new crossover for 2021

If Mazda is going to increase sales, it's going to need more crossovers. According to company CEO Masamichi Kogai, a new crossover that won't cannibalize sales of the CX-3, CX-5, and CX-9 is coming in 2021, to be built at the new U.S. factory Mazda is building in partnership with Toyota. The plant will be able to build 150,000 vehicles per year, and that full capacity will be reserved for the new CUV. With 112,235 units sold, Mazda's best-selling vehicle in the United States last year was, not surprisingly, the CX-5. With that in mind, it seems a safe bet that the new crossover will be a replacement for the discontinued CX-7 to slot above the CX-5 and below the CX-9. Kogai told Automotive News that the vehicle will be designed for America and built exclusively in the States. "We are actually going to introduce a totally new and different type of SUV," said Kogai. We don't know exactly what that means, but we hope the new model line follows Mazda's tradition of crossovers that are more fun to drive than their main competitors. Related Video:
