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.

2019 Mazda MX-5 Miata's more horsepower will cost less money

Mazda has already announced a power upgrade for the 2019 MX-5 Miata roadster after engineers tweaked the Skyactiv-G 2.0-liter inline-four for 17 percent more power and higher fuel efficiency than the outgoing 2018 model. Now we know the starting price for the soft-top version: $26,625, including destination charge, which is a $915 drop from the lowest-priced 2018 model. As is standard across the Miata lineup, output increases by 26 horsepower to 181 hp, with torque nudging up 3 pound-feet to 151 lb-ft at 4,000 rpm. Other new features also track with the changes previously announced for the 2019 Miata RF, including the telescoping steering wheel and standard rearview camera. But the soft-top version gets an available brown soft top for an extra $200 for the Grand Touring trim (a black soft top is standard), new package options at each trim level and optional traffic-sign recognition and smart city brake support, which offers automatic emergency braking at low speeds. Also new is that steering column, which is made of aluminum to save weight. Mazda will keep the six-speed manual as an option for all three trim levels, with an available six-speed automatic with paddle shifters and Sport driving mode. Standard features include LED head- and taillights, 16-inch wheels, Mazda Connect infotainment with a 7-inch touchscreen monitor, Bluetooth phone pairing and audio streaming, and keyless entry. Jump up to the Grand Touring trim starting at $31,675 and get 17-inch dark silver wheels, body-color interior trim, auto on/off headlights, auto-dimming driver's side mirror, rain-sensing windshield wipers, heated, leather-trimmed seats and a nine-speaker Bose Premium audio system, among other things. Mazda is also offering a $550 GT-S Package on the Grand Touring model with the six-speed manual, a front shock tower brace, limited-slip rear differential and Bilstein dampers. MX-5 Club models start at $30,485 and come standard with the GT-S Package goodies when equipped with the manual transmission. Automatic versions get standard heated cloth seats with contrasting red stitching, body-color interior trim, black 17-inch wheels, front air dam and rear lip spoilers.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.
