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:

2019 Mazda6 Skyactiv-D diesel caught in spy photos

We get it – we're a little sick of getting a few years of assurances that Mazda's much-anticipated diesel engine is just around the corner. First, it was going to go in the 2014 Mazda6, then it was delayed. More recently, Mazda told us it'd first land in the CX-5 – and in fact, there's a part of the Mazda USA website devoted to the diesel crossover, which makes it seem more legitimate than previous pronouncements. But the fact of the matter is, there's some unforeseen hiccup in the government approval process for this engine, likely centered around emissions standards, and it seems to be dragging on. But this Mazda6 was spotted at an EPA facility in Michigan, which gives us some hope that perhaps the company is rounding the final base on the approval process. It looks very much like an American-spec Mazda6 to our eyes ... except for the strange, possibly temporary exhaust outlets, which might be required for EPA testing. The rear looks like a current-look car, rather than the revised 2018 styling that will get the 2.5-liter turbocharged gas engine. Since the Mazda6 was originally supposed to get the Skyactiv-D engine, we can only assume that if it's at an EPA facility, Mazda is hoping to bring it to market here – likely sometime after the CX-5 goes on sale. If Mazda can get approval, it'll be another point of differentiation between the Mazda6 and its competitors – there's no currently-approved diesel sedan that's a direct match. The smaller Cruze and larger, more expensive offerings from BMW and Jaguar are about it. The fuel economy guide (PDF) produced by the EPA back in late 2017 lists both the CX-5 and the Mazda6 as having diesel engines, but neither are rated, and as we know at this point, neither are on sale or have an official timeline for doing so. We can assume anything with an application in progress made it on the list, whether approval would be granted or not. It seems unlikely at this point that Mazda would abandon the Skyactiv-D in America. It's a solid part of their strategy, although a product roadmap released a few months ago shows that Mazda expects diesel sales globally to taper off after 2020, to be supplanted by plug-in gas hybrid, EV, and fuel cell vehicles. But between now and about 2030, pure diesel cars are expected to be a small but significant portion of Mazda's product mix. We hope this means we'll see the CX-5 emerge from the approval process and hit dealer lots soon, to be followed by the 6.
