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.

Fuel cells will flop outside Japan, says VW

"It may fly within Japan, but not globally," VW's Shoji said.
It's long been battered into our beleaguered auto writer brains that the ultimate future source of motivation for tomorrow's cars and trucks is not gasoline, diesel, electricity, natural gas, propane or solar power - it's the hydrogen fuel cell. It's been the Next Big Thing since the start of Next Big Things.

Toyota Harrier gets a whale of a facelift [w/video]

Historically, the Toyota Harrier has been a doppelgänger for North America's Lexus RX - at some points, it was little more than a badge-swap and a few options away, at least aesthetically. That appears to be changing with this just-revealed new generation at the Tokyo Motor Show.
That's because this two-row, five-seat Toyota is in possession of a bold new look, dominated by a jutting, baleen-like grille edged in chrome, along with new headlamps and fascia. The greenhouse has likewise been revamped and gotten more pointed at the rump, which has new taillights, a resurfaced tailgate and a faux rear diffuser. Were it to be ported over to North American Lexus dealers intact, the Harrier's look would be jarring in light of the brand's spindle-grille-based design language, so we suspect that if the RX gets any of these updates (it was just refreshed for 2013), it will strike out on a different path visually.
Unlike the US RX, the new Harrier will rely on smaller-displacement four-cylinder engines, namely a 2.0-liter paired with a continuously variable transmission or a 2.5-liter four backed up by an electric motor. We'd like to see a smaller-displacement option for the US RX (it presently runs with 3.5-liter V6 engines in both gas-only and hybrid guise), but suspect it won't arrive until the next all-new model.
