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.

Mazda's Tokyo concepts have us wishing for more Mazdaspeed

It's been a while since we've seen any new Mazdaspeed machinery, and we're sorry to report that today isn't the day the wait ends. But if you want to see what they might look like based on Mazda's latest models, the Tokyo Auto Salon will be the place to be in a couple of weeks. Turns out the Zoom-Zoom brand has a whole raft of performance models in store for the aftermarket expo. Most intriguing to our eyes is the trio of Racing concepts – one based on the MX-5 Miata roadster, one on the CX-3 crossover, and one on the Mazda6 sedan. Each is done up in black with full aero kit, new rolling stock, and Alcantara interior. An adjustable suspension is the big change to the MX-5 – known simply as the Mazda Roadster in Japan – which also features red trim. As does the CX-3, while the Atenza (which we know as the Mazda6) goes for a more monochromatic, murdered-out appearance. The rally-prepped Mazda2 (known domestically as the Demio) focuses on a stripped-out interior with bucket seats, racing harnesses and a roll cage. There's a spec racing MX-5 in white livery with roll cage and tow hooks as well to join the Global Cup roadster we've already seen. That also goes for the RX-Vision and LM55 Vision Grand Turismo concepts which have already made the rounds but will be on display at the Tokyo salon as well. But it's those three Racing concepts that leave us salivating for production performance models to come – and hopefully come to North America in the process. Related Video:

More 2019 Mazda MX-5 Miata 30th Anniversary editions are heading to America

The 2019 Mazda MX-5 Miata 30th Anniversary edition made its debut a few months back at this year's Chicago Auto Show. The special model was limited to just 3,000 units worldwide, with just 500 heading to the U.S. Miata enthusiasts were so excited by the car that the entire allotment sold out within four hours. To help satisfy demand for this limited edition model, Mazda is allocating another 143 cars for the American market, bringing the total number of cars heading to the U.S. to 643. Note, Mazda is still only building 3,000 cars total. The 30th Anniversary Miata is available as both a roadster and the retractable hardtop Miata RF. All of them will be painted Racing Orange and will be fitted with RAYS ZE40 17-inch forged alloy wheels, orange Brembo brake calipers and Recaro seats. The cars also come with a Bose audio system, Apple CarPlay and Android Auto. The cars still retain the 2019 Miata's updated 2.0-liter inline-four making 181 horsepower and 151 pound-feet of torque. Cars equipped with the manual transmission get a limited-slip differential, Bilstein shocks and a front shock tower brace. This special edition isn't cheap. The manual soft top starts at $35,915, and the manual RF starts at $38,515. Adding an automatic ups the price by $499 on the soft top and $400 on the RF. That's up from $27,080 for a base roadster and $32,945 for a base Miata RF.
