Mazda3 diesel under consideration for US, hybrid not so much

It's been a long time coming, but we finally clapped our eyes on the real deal, officially official 2014 Mazda3 in hatchback form yesterday. Yet there's a lot more to learn about this next-generation version of what has always been one of our favorite compacts. We know that the US version will come with one of two Skyactiv engines, but what about alternatives? Will there be any... or will the gasoline-fed four-cylinders be powerful and frugal enough to carry the day?
According to Automotive News, the answer is a definite maybe. Mazda North America CEO Jim O'Sullivan has told the trade publication that his employer will consider adding the company's well-liked 2.2-liter Skyactiv diesel powerplant to the model down the road. However, the company first wants to see how the engine fares with American consumers in its big-brother Mazda6 sedan, a model that goes on sale later this year. As for a potential Mazdaspeed3 successor, mum is still the word.
Anything else? Uncharacteristically, Mazda will build a hybrid model of its new 3. We say "uncharacteristically," because the Japanese independent has long shied away from gas-electric powertrain tech. In fact, it's gone so far as to boldly announce its aversion to the technology, with auto show banners proclaiming "Not Electric. Not Hybrid. Not A Drag To Drive." Despite all that, this new generation of Mazda3 will in fact be the company's first full hybrid production model. According to AN, however, O'Sullivan says that the company has "no plans" to sell it in the US.

Mazda engineers say current Skyactiv-X might not suit U.S. market

We've been watching Mazda roll out the 2.0-liter four-cylinder Skyactiv-X engine in Japan and Europe, waiting our turn. When European authorities released fuel economy information for the high-tech motor last June, we wrote, "Mazda has yet to make an official decision on timing for the U.S market's launch of the engine." Automotive News spoke to Mazda engineers in charge of the powertrain, and based on the answers AN got, the question might not be when we get the Skyactiv-X, but if. Seems that the automaker now isn't certain whether the cost/benefit analysis for the U.S. market favors the engine, and there's concern the 2.0-liter might not be powerful enough for us with its current output of 178 horsepower and 186 pound-feet of torque. At the moment, our Mazda3 is served only with a 2.5-liter Skyactiv-G engine producing 186 hp and 186 lb-ft., not too far ahead of the Skyactiv-X. The Skyactiv-X would return better fuel economy, but requires a noteworthy price premium over the Skyactiv-G. The Truth About Cars says the Skyactiv-X has become the top-seller in the Japanese-market Mazda3, even though it costs 27% more than the base, 2.0-liter Skyactiv-G for a 9% improvement in fuel economy. Mazda's not sure U.S. customers would care much for that kind of math. Engineer Yoshiaki Yamane told AN, "Maybe U.S. customers require more power, because fuel economy is not the top requirement." There isn't much Mazda can do about the tech-heavy engine's cost, since pricey equipment like the high-pressure fuel injection and combustion systems, supercharger, three-way catalyst, and 24-volt mild-hybrid system provide the mileage gains that are the engine's reason for being. Instead, engineers are researching the system's effects with larger displacements. If it works as desired, a larger and more powerful Skyactiv-X could come to the U.S. on the large-vehicle architecture Mazda's developing for new sedans to arrive in a couple of years. That's the hope, at least. Remember, Mazda's Skyactiv-D was meant to go into the 2014 Mazda6, but didn't because Mazda said it needed more time to find "the right balance between fuel economy and Mazda-appropriate driving performance." After five years of "Soon," the engine showed up on the 2019 CX-5 that starts at $42,045. Based on that template, it could be awhile before we know how the U.S.-market Skyactiv-X story ends.

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:
