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.

An early gas-electric hybrid was developed by...Exxon?

We're not sure which aspect of Exxon's 1970s-era efforts to develop advanced and electrified powertrains is the most ironic. There's Exxon, that of the Valdez oil spill infamy, being on the leading edge of hybrids and electric vehicles. There's a boat-like Chrysler Cordova getting 27 miles per gallon. And there's the central role a Volkswagen diesel engine plays in that hybrid development. It's all outlined in an article (linked above) by Inside Climate News, and it's an amusing read. Flush with cash and fearing what it thought was peak oil production in the 1970s, Exxon funded a host of new ventures divisions geared to find alternatives to gas-powered powertrains. In the early 1970s, Exxon lured chemist M. Stanley Whittingham to develop what would become a prototype of a lithium-ion rechargeable battery. Then, in the late 1970s, Exxon pioneered the concept of using an alternating-current (AC) motor as part of a gas-electric hybrid vehicle. The company retrofitted a Chrysler Cordova (yes, that's the model Ricardo Montalban used to hawk) with a powertrain that combined 10 Sears Die-Hard car batteries, an alternating current synthesizer (ACS), a 100-horsepower AC motor, and, yes, a four-cylinder 50-horsepower Volkswagen diesel engine. The result was a rather large two-door sedan that got an impressive 27 mpg. And while US automakers didn't see the potential in the early concept, in 1980 Exxon and Toyota began collaborating on a project that would involve retrofitting a Toyota Cressida with a hybrid engine. That car was completed in 1981, and may have been one of the seeds that eventually helped sprout the concept of the Toyota Prius. Soon after rebuilding the Cressida, Exxon would get out of the advanced-powertrain-development business, as oil prices began to fall in the early 1980s, spurring cost-cutting measures. Cry no tears for the Exxon, though, as what's now known as ExxonMobil is the largest US oil company.

Automakers not currently promoting EVs are probably doomed

Okay, let's be honest. The sky isn't falling – gas prices are. In fact, some experts say that prices at the pump will remain depressed for the next decade. Consumers have flocked to SUVs and CUVs, reversing the upward trend in US fuel economy seen over the last several years. A sudden push into electric vehicles seems ridiculous when gas guzzlers are selling so well. Make hay while the sun shines, right? A quick glance at some facts and figures provides evidence that the automakers currently doubling down on internal combustion probably have some rocky years ahead of them. Fiat Chrysler Automobiles is a prime example of a volume manufacturer devoted to incremental gains for existing powertrains. Though FCA will kill off some of its more fuel-efficient models, part of its business plan involves replacing four- and five-speed transmissions with eight- and nine-speed units, yielding a fuel efficiency boost in the vicinity of ten percent over the next few years. Recent developments by battery startups have led some to suggest that efficiency and capacity could increase by over 100 percent in the same time. Research and development budgets paint a grim picture for old guard companies like Fiat Chrysler: In 2014, FCA spent about $1,026 per car sold on R&D, compared with about $24,783 per car sold for Tesla. To be fair, FCA can't be expected to match Tesla's efforts when its entry-level cars list for little more than half that much. But even more so than R&D, the area in which newcomers like Tesla have the industry licked is infrastructure. We often forget that our vehicles are mostly useless metal boxes without access to the network of fueling stations that keep them rolling. While EVs can always be plugged in at home, their proliferation depends on a similar network of charging stations that can allow for prolonged travel. Tesla already has 597 of its 480-volt Superchargers installed worldwide, and that figure will continue to rise. Porsche has also proposed a new 800-volt "Turbo Charging Station" to support the production version of its Mission E concept, and perhaps other VW Auto Group vehicles. As EVs grow in popularity, investment in these proprietary networks will pay off — who would buy a Chevy if the gas stations served only Ford owners? If anyone missed the importance of infrastructure, it's Toyota.
