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.

Why Toyota's fuel cell play is one big green gamble

Imagine going to the ballet on Saturday evening for an 8 pm performance. The orchestra begins warming up shortly before the show, but it turns out the star performer isn't ready at the appointed time. The orchestra keeps playing, doing its best to keep the audience engaged and, most importantly, in the building. It keeps this up until the star finally shows and is ready to dance ... which turns out to be ten years later. That's a Samuel Beckett play. It's also how many observers, analysts, alt-fuel fans and alt-fuel intenders feel about the arrival of hydrogen fuel cell vehicles (FCVs) – the few of them who are still in the building, that is. Toyota's hydrogen development timeline rivals that of the US space program. In fact, within the halls of Toyota alone, research on FCVs has been going on for nearly 22 years, meaning that one company's development timeline for FCVs rivals that of the US space program – it was 1945 when Werner von Braun's team began re-assembling Germany's World War II V2 rockets and figuring out how to launch them into space and it wasn't until 1969 when a man set landing gear down on that sunlit lunar quarry. The development of the atom bomb only took half as long, and that's if we go all the way back to when Leo Szilard patented the mere idea of it, in 1934. Carmakers didn't give up on hydrogen in spite of the public having given up on carmakers ever making something of it, so there was a good chance that hydrogen criers announcing the mass-market adoption of periodic chart element number two one would eventually be right. Now is that time. And Toyota, not alone in researching FCVs but arguably having done the most to keep FCVs in the news, isn't even going to be first to market. That honor will go to Hyundai, surprising just about everyone at the LA Auto Show with news of a hydrogen fuel cell Tucson going on sale in the spring. The other bit of thunder stolen: while Toyota's talking about trying to get the price of its offering down to something between $50,000 and $100,000, Hyundai is pitching its date with the future at a lease price of $499 per month ($250 more than the lease price of a conventional Tucson), free hydrogen and maintenance, and availability at Enterprise Rent-A-Car if you just want to try it out. We've seen and driven Toyota's offering and we all know its success doesn't depend on cross-shopping, showroom dealing and lease sweeteners.

Carmakers, NHTSA to unveil auto-emergency braking agreement tomorrow

Happy St. Patrick's Day Eve. Tomorrow, there will be green beer, corned beef and cabbage, and automatic emergency braking for all. Weird combo, we know. But on St. Patty's we can expect an official announcement from a pact of automakers making auto-braking systems standard equipment by 2022. That's per a report from Reuters, which cites three sources familiar with the plans. Originally announced in September 2015 by 10 automakers and the National Highway Traffic Safety Administration, the agreement is expected to be even larger when the details are unveiled tomorrow. According to Reuters, the manufacturers of 99 percent of the US domestic market's vehicles will be represented by the new agreement. It's believed that standard AEB systems could prevent thousands of accidents across the country. Expect more on the official announcement when it's made. Related Video:
