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.

NHTSA releases updated Takata airbag recalled cars list, but it still has errors

Unfortunately, the government's list still contains errors.
The National Highway Traffic Safety Administration has issued an updated list of vehicle models that it's urging owners to repair under the mushrooming Takata airbag inflator recall. The latest version adds vehicles from new automakers like Subaru and Ford that are missing from the original announcement, and it also removes erroneous entries from General Motors, leaving only the 2005 Saab 9-2X (a reskinned Subaru WRX), and the 2003-2005 Pontiac Vibe, a joint project with Toyota.

Mazda planning more powerful MX-5?

The new Mazda MX-5 will be available with a 1.5-liter four with 129 horsepower or 2.0-liter with 155. And while either engine may seem a tad on the small side for a sports car, they keep perfectly in line with what the Miata is all about. That doesn't mean, however, that more powerful options aren't under consideration. Speaking with Motoring.com.au at the launch of the new MX-5, Mazda's global PR chief Kudo Hidetoshi revealed that two options are under consideration. One would be a larger engine, and the other a turbocharged version of the existing 2.0. The former option would deliver the extra punch while keeping things naturally aspirated and free from turbo lag, but could throw off the weight balance Mazda has worked so hard to preserve. The more likely option, then, would be the turbocharged route that would allow the Zoom-Zoom brand to keep the roadster light and nimble, while still delivering an extra boost. Neither would be without its challenges, but if overcome, the resulting high-performance model could be sold as a Mazdaspeed model in some markets and as an MPS version in others. And, even if such a performance roadster were to get the go-ahead for production in some markets, there's no guarantee that it will be sold in the United States. Here's hoping. Related Video:
