Why Mazda’s Skyactiv-X compression-ignition engine is a smart hedge bet

Mazda has cracked the code on a compression-ignition engine, called Skyactiv-X (which utilizes SCCI, or Spark Controlled Compression Ignition). That's a neat engineering accomplishment, sure, but why is the tiny company investing big dollars in fancy tech that's frustrated the much larger companies who've investigated it? In this case, Mazda is peering into a crystal ball to consider how best to flow with a few troubling tides. One is the premature handwringing about the death of the internal combustion engine, another is Europe's swing away from diesel engines. Skyactiv-X seems, at this juncture, a hedge bet against both aspects. EV infrastructure lags massively behind our petroleum infrastructure — no shock there. Mazda claims the tech will net 20-30 percent gains in fuel efficiency over its current gasoline engines and about matching its diesel engine. And that's without any onboard hybrid tech, so that staves off the inevitable necessity to fully adopt electrification for a while — this is assuming that, at some point, it won't be practical to sell a non-hybrid or non-EV. At what date that happens is open to debate, but as I said above, technology like this kicks that decision point down the road a bit. Mazda is here translating research dollars into time, allowing its engine factories a few more years of probably profitable production of internal-combustion engines before retooling, and before somebody needs to pour a massive amount of money into a broad EV charging infrastructure to replace gas stations. None of this is happening fast enough for a wholesale transition to EVs anytime soon. So, that's one bet hedged. The next is Europe's declining interest in diesel engines for mainly health reasons. Just about a week ago, The New York Times posted an excellent primer on this issue, which is somewhat controversial in Europe. Germany's auto industry, a huge portion of its economy, is heavily invested in diesel tech and seriously opposed to proposals in Britain and France to eliminate the technology, which creates unhealthy diesel particulate emissions. The German industry is hoping Band-Aids like pollution-reducing measures will help them, but after a massive and widespread emission cheating scandal, its credibility is at a nadir. It seems like consumers have sensed which way the wind is blowing, and it has hurt sales. The NYT reports that diesel sales in Germany alone — remember, bastion and originator of diesel technology — are down 13 percent.

Ruminations in winter | 2016 Mazda MX-5 Miata long-term update

Winter is an odd time for our 2016 Mazda MX-5 Miata Club long-term tester. In the summer, the track beckons. Fall and spring bring top-down adventures at sunset. But our Miata is a little out of its enthusiast element when the weather is harsh and our moods grow as gray as a January day in Michigan. Sure, there's the occasional snowstorm, and equipped with winter tires the Miata can be a fun toy. But what about when it's just cold and dreary? We had a lot of time to reflect on our MX-5 these past few months, and we still managed to find enjoyment in the little things - even though admittedly this is not the time of year when the Miata shines. For starters, we taught associate video producer Amr Sayour how to drive a stick shift with the Miata. With its agreeable clutch and short throws, the six-speed manual was the perfect learning instrument for Sayour. His teacher, Adam Morath, actually had to show him how to stall. Arguably, learning to drive a manual isn't a little thing, but it was these run-of-the-mill events that showcased the Miata could be more than tolerable in winter. Associate Editor Joel Stocksdale used it for a 500-mile roundtrip to pick up a new pet and found it was a little tight for dog and driver. Though Stocksdale still enjoyed the sports-car feel, he came to the conclusion that "Miata is always the answer, but not always the best one." We also quickly realized the MX-5 isn't a great commuter car, nor did we expect it to be. It's low to the ground. It's loud. The small cabin has a greenhouse effect, and the windows fog easily. "If you have a Miata, it will creak and rattle in the winter. A lot. Nothing out of the ordinary here - this is a convertible with a lot of flexy parts - but something the casual shopper might not be aware of," Editor-in-Chief Mike Austin noted. Still, he found ways to have fun. "On the upside, winter tires = low-speed power oversteer." We had a lot of time to reflect on our MX-5 these past few months, and we still managed to find enjoyment in the little things. Speaking of those snowshoes, Stocksdale said they made our Mazda a "perfectly acceptable winter ride." Keeping the traction control on, he navigated his neighborhood roads in packed snow with little trouble. Like Austin advised, be aware of the ground clearance; Stocksdale got hung up in deep snow while attempting to scale his driveway.

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.
