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.

This is the 2017 Mazda MX-5 RF targa-roof fastback

We knew Mazda was going to introduce a new Miata variant ahead of the 2016 New York International Auto Show, but the smart money was on a power retractable hardtop version that largely mirrored the last-gen car's folding number. So it was a surprise when the new 2017 Mazda MX-5 RF – retractable fastback – drove onto the stage sporting wild buttresses and a hide-away targa roof panel. The buttresses lift up and swallow the rear window and roof panel in a matter of seconds, and then the buttresses snug back down. This leaves a hoop spanning the buttresses, but at least it's done up in black to be less visually apparent. The result is more of a targa roof experience, rather than the previous PRHT which gave occupants essentially the same experience as the soft-top with the top down. No matter. The result is stunning, and will differentiate the RF even more from the standard MX-5. Mazda designers took extra care to make sure the interface between the MX-5's dramatic fenders and the trailing edges of the roof support provided enough visual drama. Mission accomplished, we'd say. We can't take our eyes off that part of the car. View 13 Photos As you might expect, mechanical changes seem to be minor, although we'll be asking for detailed specs. Both the 1.5- and 2.0-liter engines will be available globally, but only the 2.0-liter Skyactiv-G engine will be sold in the US. The roof can be operated at up to 6.2 mph. Mazda claims the truck space is unaltered from the soft-top model. We don't yet know how much, if any, the RF's mechanism adds to the bantamweight roadster, nor the premium it'll command. Expect those details closer to launch. Related Video:

Premium design and diesels: Mazda may be the next VW

At the Chicago Auto Show, we had a chance to sit down with Jacob Brown, a Mazda PR representative, and Jacques Flynn, a lead exterior designer at the company, to talk about design and where the company is going. One of the themes of our discussion was the company's desire to move its lineup toward a more premium, upscale feel and image – both in terms of vehicle design and powertrains. We realized the company may be looking to take a page from Volkswagen's American playbook, positioning itself as a prime purveyor of affordable, upscale – and most importantly, fun to drive – automobiles. In the case of design, Flynn talked about how Mazda's KODO design language is going to evolve; that the goal is to simplify and refine the look. We discussed the CX-5 as an example of this evolution. Flynn pointed out that the goal was to add more refinement and simplicity, and showed how Mazda achieved this on the CX-5 by straightening the curves from the previous model to give it more visual length and a more taut shape. The grille also was given more depth and detailing, which isn't simplified per se, but does provide a more premium look. View 9 Photos Mazda's upcoming diesel engines are another piece to Mazda's premium puzzle. The company will finally offer a diesel on the CX-5. While Mazda planned not to use urea-injection, it finally resorted to the system so the engine could both meet performance benchmarks and emissions standards. In addition to the efficiency of the engine, Brown said that diesel engines have a premium nature for buyers. This is due in part to the luxury automakers that mainly offer them in the US, such as BMW and Mercedes-Benz, and to the fact that the technology will add some cost to the product. If all of this sounds familiar, it's because you know these characteristics used to describe Volkswagen: a company known for upscale, affordable cars, providing great driving dynamics – and formerly, for efficient and fun-to-drive TDI diesel engines. While we didn't touch on the driving experience of modern Mazdas in our interview, you can simply look at any of our reviews to see that we generally like what the company builds. The only downside is that we may have to wait a while for some models, and others may never show up here. Brown and Flynn both said that the Mazda2 is unlikely to be offered in the US as anything other than the Toyota Yaris iA, since it's hard to convince people that a subcompact is premium. No surprise there.
