Toyota Recalling Millions Of Cars Over Multiple Concerns

Toyota Motor Corp. is recalling nearly 1.8 million vehicles in the U.S. for various safety problems, including air bags that may fail to deploy. The Japanese automaker announced the U.S. recall Wednesday as part of a broader recall of 6.39 million vehicles - and 27 Toyota models - globally. In the U.S., the recall includes: - 1.3 million vehicles with faulty electrical connections that could cause the air bags to deactivate. Included are the 2009-2010 Corolla, 2009-2010 Matrix, 2008-2010 Highlander, 2009-2010 Tacoma, 2006-2008 RAV4, 2006-2010 Yaris and 2009-2010 Pontiac Vibe. If the air bags deactivate, they could fail to deploy after a crash. - 472,500 small cars with defective springs in the front seat rails, which could prevent the seats from locking in place. Included are the 2006-2010 Yaris hatchback, 2007-2010 Yaris sedan and the 2008-2010 Scion XD. Toyota said it is currently working on remedies for the problems. Dealers will replace the defective parts for free when replacement parts are available. The Pontiac Vibe, which is made by General Motors Co., is included in the recall because Toyota designed and engineered it for GM when the two companies shared a factory in California. GM says 40,500 Vibes will be recalled, and says GM dealers will make repairs when Toyota sends them the parts. The air bag issue is unrelated to a separate GM recall of 2.6 million vehicles for an ignition switch defect that can also deactivate the air bags. The Vibe isn't included in that recall. Toyota said no injuries or crashes have been reported related to the recalls. By region, the recall affects 2.3 million vehicles in North America, 1.09 million vehicles in Japan and 810,000 vehicles in Europe. Other regions affected by the recall include Africa, South America and the Middle East. The recall is one of Toyota's largest since 2009 and 2010, when the company issued a series of recalls totaling more than 10 million vehicles for various problems including faulty brakes, sticky gas pedals and ill-fitting floor mats. Toyota is under pressure to announce recalls quickly after a U.S. government investigation found it hid information about past defects. Last month, the company agreed to pay $1.2 billion to settle that investigation. It also paid fines totaling $66 million to the U.S. government for delays in reporting unintended acceleration problems.

Toyota, Honda, Nissan and more collaborating to increase fuel efficiency

Toyota, Honda, Mazda, Nissan, Subaru, Mitsubishi, Suzuki and Daihatsu have announced an alliance that will see a push to improve fuel economy from both gas-powered and diesel-powered engines by as much as 30 percent before the end of the decade.
The newly assembled Research Association of Automotive Internal Combustion Engines put the roughly $20-million project together, with the Japanese government committing to half the cost while the eight manufacturers will chip in the rest.
According to Automotive News, the automakers will team up and share basic research on internal-combustion engines in a bid to cut costs. Eventually, the results of the research will find its way into a production vehicle, although it's unclear just when we'll see the fruits of this partnership on the road.

Toyota finds 10% MPG improvement in hybrid PCU

Keeping up its from-all-angles approach to efficiency, Toyota has found yet another way to eke out up to ten percent more precious MPGs in its hybrid vehicles, this time electronically. The automaker has announced the development of new silicon carbide (SiC) power semiconductors for use in power control units, which it will begin testing on Japanese roads within the next year. The PCU using the silicon carbide compound offers less electrical resistance, which improves efficiency when passing current between the battery and electric motor. It also loses less power after shutting off, and can operate at a higher frequency. The net power loss of the new PCU is just one-tenth of the current silicone-only version (the latter accounting for 20 percent of total electrical power loss in today's hybrids). The result, so far, is a claimed five-percent improvement in fuel economy in test vehicles, with the potential of ten percent by the time the new SiC power semiconductor comes to market. Additionally, the carbide wafers allow for smaller a power module, coil and capacitor, thus allowing the entire PCU to be 80 percent smaller (see the side-by-side comparison in the accompanying photo, which you can click to enlarge). We've got a while to wait before we start to see the carbide technology to start making a real-world impact. Toyota aims to begin using the SiC units in 2020. By then, with improvements in the company's other key efficiency factors - engine technology and aerodynamics - cars like the Prius will likely see significant gains in fuel economy.

Toyota Develops 'Diamond-like' Computer Chips to Boost Hybrid Mileage May 20, 2014 Toyota City, Japan – Toyota is using one of the hardest materials in nature after diamonds to develop a semiconductor chip it hopes will improve the fuel efficiency of its hybrids, such as the Prius, by as much at 10 percent. The company and its partners announced today that they have developed a silicon carbide (SiC) power semiconductor for use in automotive power control units. Toyota plans to begin test-driving vehicles with the technology on public roads in Japan within a year. The chips, made from carbide - one of the hardest materials in nature, theoretically have superior characteristics such as one-tenth the electrical power loss and 10 times the drive frequency. Toyota said the chips would also allow it to reduce the size of current automotive power control units by 80 percent.
