Green self-driving cars take center stage in Tokyo

Visions of cars that drive themselves without emitting a bit of pollution while entertaining passengers with online movies and social media are what's taking center stage at the Tokyo Motor Show. Japan, home to the world's top-selling automaker, has a younger generation disinterested in owning or driving cars. The show is about wooing them back. It's also about pushing an ambitious government-backed plan that paints Japan as a leader in automated driving technology. Reporters got a preview look at the exhibition Wednesday, ahead of its opening to the public Oct. 30. Nissan Motor Co. showed a concept vehicle loaded with laser scanners, a 360 degree camera setup, a radar and computer chips so the car can "think" to deliver autonomous driving. The Japanese automaker called it IDS, which stands for "intelligent driving system." Nissan, based in Yokohama, Japan, said it will offer some autonomous driving features by the end of next year in Japan. By 2018, it said vehicles with the technology will be able to conduct lane changes on highways. By 2020, such vehicles will be able to make their way through intersections on regular urban roads. Nissan officials said they were working hard to make the car smart enough to recognize the difference between a red traffic light and a tail light, learn how to turn on intersections where white lane indicators might be missing and anticipate from body language when a pedestrian might cross a street. Nissan's IDS vehicle is also electric, with a new battery that's more powerful than the one currently in the automaker's Leaf electric vehicle. Although production and sales plans were still undecided, it can travel a longer distance on a single charge and recharge more quickly. A major challenge for cars that drive themselves is winning social acceptance. They would have to share the roads with normal cars with drivers as well as with pedestrians, animals and unexpected objects. That's why some automakers at the show are packing the technology into what looks more like a golf cart or scooter than a car, such as Honda Motor Co.'s cubicle-like Wander Stand and Wander Walker scooter. Instead of trying to venture on freeways and other public roads, these are designed for controlled environments, restricted to shuttling people to pre-determined destinations. At a special section of the show, visitors can try out some of the so-called "smart mobility" devices such as Honda's seat on a single-wheel as well as small electric vehicles.

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.

GM repairing 40,500 Pontiac Vibes as part of Toyota airbag recall

General Motors has confirmed to Autoblog that the Pontiac Vibe is included in Toyota's just-announced recall action. The Vibe and the Toyota Matrix share a large number of parts, including the affected cable to the airbag.
"About 40,500 Pontiac Vibes from the 2009-2010 model years are included in the Toyota recall. Toyota designed and engineered the Vibe for Pontiac. GM will service customers with these vehicles when Toyota makes the parts available," said GM recall spokesperson Alan Adler to Autoblog in an email.
The recall covers 1.3 million Toyota units in the US, including 2009-2010 Corolla, Matrix and Tacoma, the 2008-2010 Highlander, the 2006-2008 Rav4 and 2006-2010 Yaris, plus the addition of the 2009-2010 Vibe. The models all have their airbag module attached via a spiral electrical cable. The connections on this cable can be damaged when turning the steering wheel. Once broken, the airbag deactivates and the airbag warning light comes on. Toyota has an improved part, but it's still making preparations to begin repairs. It will begin notifying owners soon.
