Toyota will steer clear of driverless cars

Toyota executives say the company's primary focus is on safety. At least for the time being, that means the company won't pursue development of a driverless car.
Speaking at the company's advanced safety seminar in Ypsilanti, MI, Thursday morning, Seigo Kuzumaki, Toyota's deputy chief safety technology officer, said that Toyota envisions a future driving environment that optimizes the best of both humans and computers, not choosing one over the other.
"Toyota's main objective is safety, so it will not be developing a driverless car." - Seigo Kuzumaki

Toyota issues multiple recalls for 6.4 million vehicles worldwide

It looks like 2014 may go down as the year of recalls. We were already at a record pace, and now it seems Toyota is recalling 6.39 million vehicles worldwide, including about 30 of its models for a variety of problems. None of the faults have caused any injuries or fatalities, but there have been two reports of fires caused by a defective engine starter motor.
Toyota's numbers show 1.772 million vehicles being recalled in the US, but that includes some overlap because the Yaris is being repaired for multiple faults. According to The Detroit News, there are 2.36 million affected models in all of north North America, 1.09 million in Japan and 810,000 in Europe, plus smaller numbers in other regions.
Among the vehicles recalled in the US are 1.3 million units of the 2009-2010 Corolla, Matrix and Tacoma, the 2008-2010 Highlander, the 2006-2008 Rav4 and 2006-2010 Yaris. The problem is that the driver's airbag module is attached via a spiral electrical cable. The connections on the cable can be damaged when the steering wheel is turned, which deactivates the airbag and causes the airbag warning light to come on. Toyota is replacing the cable with an improved part, but it's still making preparations to begin the repair. The company is sending affected owners notifications in the mail. According to The Detroit News, an unspecified number of Pontiac Vibe vehicles are also included in this recall because it shares the part with the Matrix.

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.
