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.

Toyota expands airbag recall to 2.27M vehicles worldwide

Was your Toyota inspected under the company's recall campaign for faulty airbag inflators last year? You might have another trip ahead to have it repaired again. The automotive giant says that it found "the involved serial numbers provided by the supplier were incomplete, and did not include all of the potentially involved inflators," according to its official announcement. That means more replacements are needed.
Toyota's April 2013 inflator recall covered the Corolla, Matrix and Tundra from the 2003 and 2004 model years, the Sequoia from 2002 to 2004 and the Lexus SC 430 from 2002 to 2004. At the time, the company said it would need to inspect about 510,000 vehicles in the US but only expected to replace around 170,000 inflators.
However, the latest announcement increases that figure to about 766,300 vehicles in the US. Toyota spokesperson Cindy Knight told Autoblog that the new amount is the combination of owners who need to have their vehicle looked at again and those who didn't come in for the initial recall. The company learned about the problem when Takata, the supplier, provided it with an improved list of the faulty part's serial numbers. According to The Detroit News, the latest recall affects about 2.27 million vehicles from them worldwide. Knight said owners would receive notification of the problem around the end of the month but repairs would come in phases because the automaker doesn't have all of the necessary parts at the moment.

Toyota to buck engine downsizing trend, may go larger and turbo-free

Turbocharging isn't really Toyota's specialty, and the Japanese automaker isn't being shy about acknowledging it. Koei Saga, a senior managing officer in charge of drivetrain research and development, says that eschewing turbos and increasing displacement of engines using the Atkinson cycle can produce better power gains without sacrificing fuel economy, Automotive News reports.
Toyota is investing heavily in larger-displacement Atkinson-cycle engines in addition to turbocharged engines, but Saga doesn't think the automaker will use turbocharging across many product lines. He apparently remains unconvinced that the technology "makes the world better."
In Toyota's eyes then, Atkinson cycle engines do make the world better, and here's how. Their pistons complete four processes - intake, compression, power and exhaust - in one revolution of the crankshaft, and the power stroke is longer than the compression stroke. Traditional Otto cycle engines require two crankshaft revolutions to accomplish those same four operations and have equal-length compression and power strokes. Atkinson cycle engines are more efficient, but less power dense, though increasing displacement can offset that shortfall.
