How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

2020 Mazda CX-3 adds active safety features plus Apple CarPlay, Android Auto

The CX-3, Mazda's smallest crossover offering, shrinks its showroom footprint for 2020, as the brand makes room for the newly introduced CX-30 just above it in the lineup. The 2020 CX-3 is cut back from three trim levels to just one, although that single offering is bolstered with additional standard equipment including Apple CarPlay and Android Auto, which come to the CX-3 for the first time. Even more significantly, Mazda is adding as standard a batch of active-safety features that includes forward collision warning with automatic emergency braking and pedestrian detection, lane departure warning, adaptive cruise control with stop-and-go, and automatic high beams—formerly an option package costing $1,100. Blind-spot monitoring and rear cross-traffic alert were already standard and continue. The 2020 CX-3 also gains automatic climate control, a head-up display, rain-sensing wipers and LED exterior lighting. For all that, the 2020 CX-3's prices rise just $250 over the 2019 CX-3 figures. The starting figure for the 2020 Mazda CX-3 Sport is $21,685 with front-wheel drive or $23,085 with all-wheel drive (including $1,045 destination). The other news for the 2020 CX-3 is that the Touring and Grand Touring trims have been dropped. Which means that the features exclusive to those trims, such as leather seating surfaces, a power sunroof, heated seats, a heated steering wheel, and a power driver's seat, are no longer offered. Buyers seeking those niceties perhaps are now expected to step up to the CX-30 — although it's not a big leap, with the CX-30 starting at $22,945.

Why is it called Mazda CX-30? Plus other questions answered

GENEVA — Mazda just introduced its latest crossover, the CX-30, and it left us raising an eyebrow. It's planned for a global release, including the United States, and it's supposed to slot between two compact crossovers that one might not think had room for another model. Plus it has a name that doesn't fit Mazda's typical nomenclature. So we thought we'd take a little time to explain some of those things, starting with the name. Mazda arrived at the CX-30 name because of a self-created problem: the Chinese Mazda CX-4. The CX-4 name would be perfect for the CX-30, since it would fall right between the CX-3 and CX-5 where it's positioned. But with the name taken, and evidently no plans to discontinue, replace, or rename that Chinese model, Mazda needed something else, and fractions and decimals weren't on the table. So appending a zero was the plan. Talking with a Mazda representative, there were hints, though no concrete confirmation, that this naming scheme could possibly spread throughout the Mazda line. There would be advantages to such a system, such as bringing the CX-30 into line with other Mazda products, but it would also provide room for other in-between models named CX-35, CX-25, etc. Now for the size. Mazda says it fits between the CX-3 and CX-5, both of which will be sold alongside it for the foreseeable future. But is it closer to one than the other? Length-wise, the CX-30 is 4.7 inches longer than the CX-3 and 5.9 inches shorter than the CX-5. It's also an inch wider than CX-3 and 1.8 inches narrower than CX-5. Interestingly, the CX-30 and CX-3 are the same height, which is 5.9 inches shorter than the CX-5. The CX-30 does have a bit more ground clearance than the CX-3, but only by a few hundredths of an inch. To add some context outside the Mazda brand, the CX-30's size also puts it on par with crossovers such as the Mitsubishi Eclipse Cross, Subaru Crosstrek and Jeep Compass. All of those are sort of in-betweeners themselves. By contrast, the CX-3 is one of the smallest subcompact crossovers and aligns more closely with a Hyundai Kona. In other words, there actually was a segment gap Mazda could fill as the CX-30 fall pretty squarely between the CX-3 and CX-5. As such, we also imagine that pricing will fall between the two. The CX-3 starts at $21,435 and the CX-5 at $25,395. So about $23,000 seems reasonable for the base Skyactiv 2.0-liter engine, and probably more for the Skyactiv-X engine.
