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.

Final decision on Toyota/BMW sports car due by year end

BMW and Toyota signed a memorandum of understanding to share technology and build a sports car way back in 2012, and months later, they made that partnership official. This oft-rumored model from two auto industry titans still hasn't hit the road, and the time has come to make a final decision about its future. Thankfully, the model's fate is just a few months from being known. "By the end of the year we will approve whether or not we will make it," a Toyota spokesperson said about the sports car project, according to Automotive News Europe. "The whole study before that, on what kind of platform, on what kind of architecture, that's been progressing quite well. We haven't yet decided to give the green light to the project, but it's coming up." The collaboration is supposed to result in jointly developed fuel-cell tech, composites, and research into lithium-air batteries. Little is officially known about what Toyota and BMW are planning for the sports car project, but there are plenty of rumors about what's in store. Both automakers are supposed to get their own version of the vehicle. Some reports say the Japanese model will be the revival of the Supra, and the Bimmer-badged one might end up being a replacement for the Z4. The potential powertrains have been suggested as a German-sourced, turbocharged inline six with rear-wheel drive and a super-capacitor-powered plug-in hybrid with all-wheel drive.
