Mazda-Toyota partnership has us dreaming of a rotary hybrid

As you may have seen, Mazda and Toyota are going to be working a little more closely with each other. In their announcement, the two companies said they'd be building an American assembly plant together, and working on electric vehicle technology. But one of the companies' goals got our mental gears turning: It's listed as "Expand complementary products," and it's left very open-ended. The companies say they "will further explore the possibilities of other complementary products on a global level." These are in addition to Mazda providing the Mazda2 to Toyota as the Yaris iA, and Toyota providing Mazda a commercial van to sell in Japan. So what could these future complementary products be? We have a couple of ideas, one that's ludicrous but awesome (and, sadly, probably won't ever happen), and the other grounded in reality. Let's start with the fun one. What's the one thing Mazda fan has been wanting for years? A rotary sports car, of course! And while Mazda has repeatedly said that it has a small band of engineers plugging away at the spinning triangle problem, the odds of Mazda putting it into production have been slim. The inherent thirst of the rotary would make it tough to introduce when fuel economy regulations have been tightening. Plus, Mazda is a small company that needs to stretch every dollar, and having a one-off engine not based on anything else would be expensive. How could Mazda get around these obstacles? This is where the partnership with Toyota comes in, in our long-shot fantasy. Aside from having deep pockets, Toyota has a wealth of knowledge in the realm of hybrids. Thus, why not a rotary hybrid? Electrifying their oddball motor would fix two issues. One is obviously the fuel economy, since the gas engine wouldn't have to run all the time. The other is in providing torque. Rotaries infamously have little torque, especially down low, so adding an electric motor would allow this hypothetical rotary sports car to have a grunty low end, while still providing the Everest-high redline rotary fans like. The idea would be sweetened with the solid-state batteries that Toyota is developing, which could provide lots of electricity without weighing a ton. The rotary-electric mashup notion isn't totally alien to Mazda, either, since the company created an electric Mazda2 with a rotary engine for a range extender — albeit for different reasons. The company even filed a patent for the rotary range extender recently.

The Mazda MX-5 Miata is truly a four-season sports car

For all intents and purposes, the Mazda MX-5 Miata is a product of California. I know it says Hiroshima on the shipping container, but the car belongs to the Golden State as it was dreamt up in Irvine and honed its driving skills on the roads near Santa Barbara. And logic would dictate the Miata would be useless in any situation other than direct sunlight. That's what drivers from other states would think, anyway. It's the time of year when those of us from the west coast fly out to places where it's snowy and icy and everyone laughs at us because the cold and white stuff essentially shuts us down. Make fun of Californians driving in the rain or freaking out when the outside temperature dips below 55 degrees. What can we say, we're just out of our element. Perhaps, then, it's surprising the Miata handles snow a lot better than I do. I found this out when Mazda sent me to Crested Butte, CO, for a little fun on a frozen track. Yes, there was a lot of sideways action, but it had more to do with the two California residents inside than with the car. The company really invited journalists to Colorado to get an idea of how its all-wheel-drive crossovers perform when things get snowy and icy. But the real show was watching how we navigated the autocross course they set up for the rear-drive Miatas that Mazda brought along. The Miata had a good heater, but it was my laughter caused by immense admiration that kept me from freezing my fingers off. Armed with a set of Bridgestone Blizzak winter tires, the Miata performs just about how you'd expect it to – if you're light on the gas and quick with the steering and have a good amount of patience in you. It all works well if you're a pro driver, less so if you're not a frequent track visitor, regardless of the weather. But fortunately we were using the fourth-generation Miata, which has to be the most forgiving sports car ever. On pavement, it behaves like a compact hatchback. Put it in sixth and it's relaxed and compliant, with a ride that doesn't beat you up and an engine that knows when you just want to get where you need to go. Provoke it, however, and it rewards you with predictable responses from the controls. It does the same thing on ice, if you have a firm grasp on how a car responds to the frozen stuff. Starts are tricky, even in second gear, if you underestimate the power from the 2.0-liter four.

Mazda hard at work on Skyactiv 2 engine technology

As Mazda continues the current rollout of its still-new Skyactiv technology, the automaker is already looking at improving its family of engines for even better fuel economy and emissions reductions. Automotive News reports that with stricter fuel economy and emissions regulations planned for 2020 and 2025 in Europe, Mazda will likely release engines with next-generation Skyactiv 2 technology by the end of this decade, and Skyactiv 3 units just five years later.
The latter is expected to focus on improved engine cooling and lessening energy losses, but the big news in AN's report is that the next-gen Skyactiv 2 engines will use Homogeneous Charge Compression Ignition, or HCCI. This type of ignition is very similar to how a diesel engine operates (with high compression and using the compression stroke for fuel combustion rather than spark plugs), a method said to provide a cleaner and more efficient fuel burn - to the tune of a 30-percent improvement in fuel economy compared to current Skyactiv engines. Other automakers, including Hyundai, have already announced they are developing HCCI powerplants with similar technology and characteristics, so Mazda likely won't be a lone wolf here.
Equipped with HCCI technology, Mazda figures to be able to compete with larger automakers in terms of fuel economy and emissions without resorting to hybrid powertrains, continuously variable transmissions or automatics relying on more forward gears (eight or more) for optimal efficiency. Some of the challenges of HCCI, according to AN, include the need for better engine cooling, risk of misfire at high and low rpm and uneven engine performance based on fuel properties.
