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 Miata could get retractable hardtop in New York

The upcoming New York Auto Show just got a little more exciting because Mazda could debut the latest MX-5 Miata with a power retractable hardtop there. The best evidence comes from Autocar, which has an image of Mazda's invitation. The message promises a "world premiere" in the Big Apple and further teases, "Help us blow the lid off the New York Auto Show." The last Miata PRHT made up 52 percent of the roadster's sales mix in the US, so creating another one is an easy decision for the company. According to Autocar, expect the new roof mechanism to be lighter and more compact than the previous design. It would still add some weight compared to the cloth top, but customers would get the added insulation and security from the hardtop. With the NC PRHT as a guide, don't expect many changes for the new other than the roof. The 2.0-liter four-cylinder with 155 horsepower and 148 pound-feet of torque with either the six-speed manual or automatic should still make for an exciting drive. The hardtop just makes life a little more comfortable if you have to deal with rain or snow for part of the year. We can't wait to see it. Related Video:

2019 Mazda CX-5 Review and Buying Guide | The driver's choice

The 2019 Mazda CX-5 stands out in an ever-expanding field of similarly sized compact crossovers. There are several good options for shoppers looking to replace the traditional family sedan with something that sits up a little higher and offers some added utility via a reasonably sized open cargo area instead of a closed-off trunk. But if you really enjoy spending time behind the wheel, there isn’t a small crossover that can match the Mazda CX-5Â’s blend of excellent driving dynamics, practicality and affordability. For that reason, weÂ’d suggest that everyone shopping in this segment should take the CX-5 for a test drive. WhatÂ’s new for 2019? The CX-5 gets its first significant update since being completely redesigned for 2017. There are two new engine choices. A 2.5-liter turbocharged four-cylinder is the more powerful option the CX-5 has always needed, while the new 2.2-liter diesel engine is the answer for those who want better fuel economy. Every CX-5 benefits from a retuned suspension setup and MazdaÂ’s G-vectoring Control Plus system, which are intended to improve the 2019 CX-5Â’s handling. A revised infotainment system loses its touchscreen capability but now offers Apple CarPlay and Android Auto capability (it is not, however, the all-new and greatly improved system found in the Mazda3). Also new for 2019 is a top-spec Signature trim level that adds a layer of wood and chrome trim to the interior to go along with attractive brown leather upholstery and a 360-degree camera monitor. A set of 19-inch Dark Silver aluminum wheels and unique badging round out the noteworthy Signature upgrades. WhatÂ’s the CX-5's interior and technology like? The CX-5 boasts a handsome, upscale design with materials to match. The cabin conveys the more premium vibe that Mazda is increasingly shooting for – it also makes a more emotional connection than the typical cardboard box on wheels. Its top two trim levels, Grand Touring Reserve and Signature, boast seats that are heated all around and ventilated up front, covered in high-quality leather with contrast French stitching. There's stitching on the dash too, though it goes through rubbery stuff. The padded and stitched pleather on the doors and center console are a nicer touch, as is the subtle dark wood and alloy trim – especially the air vents that seem to jut out from within the dash.
