Honda, Nissan, and Toyota expand Takata recall by millions worldwide

Honda, Nissan, and Toyota are expanding their global Takata airbag inflator recalls to cover millions of additional vehicles. Toyota alone is adding about 5 million vehicles to its campaign globally, and over 600,000 of those are in the US, according to Automotive News. Nissan's expansion includes an estimated 1.56 million cars worldwide, including about 326,000 in North America, but the exact models from the company are not yet known. According to Automotive News, Honda has also announced plans to increase the scope of its campaign but hasn't yet disclosed specific models, total numbers, or their location. Company spokesperson Chris Martin tells Autoblog that none of these vehicles are in the US, though. In the US, Toyota is replacing the driver's side front inflators on 160,000 examples of the 2004 and 2005 RAV4 nationwide. It's also swapping out the front passenger side parts for 177,000 units of the 2003 and 2004 Tundra (pictured above) and 2004 Sequoia. The automaker is also expanding its regional recalls in high-humidity areas to include the passenger-side inflators of 300,000 more vehicles. In total, the affected models are 2005-2007 model-year Corolla, Matrix, Sequoia, and Lexus SC; plus the 2005-2006 Tundra is included, as well. All of the states that are covered by this campaign are listed in Toyota's announcement, below. In a statement to Autoblog, Nissan said that it's currently working with the National Highway Traffic Safety Administration on this campaign. "We expect to have a more formal statement and additional information by Friday, May 15," the company said. TOYOTA EXPANDS TAKATA AIRBAG SAFETY RECALLS TORRANCE, Calif., May 12, 2015 – Toyota Motor Sales, U.S.A., Inc. today announced that it is expanding its recalls involving Takata air bag inflators. First, Toyota will conduct a recall to replace Takata-supplied driver front airbag inflators on approximately 160,000 model year 2004 and 2005 RAV4 sport utility vehicles. The inflators could potentially be susceptible to rupture when deployed in a crash, increasing the risk of injury to vehicle occupants. For similar reasons, Toyota will expand two existing recalls for Takata-supplied front passenger airbag inflators, namely: Toyota's nationwide recall launched in April 2013 will expand to include approximately an additional 177,000 model year 2003-2004 Tundra and model year 2004 Sequoia vehicles.

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.

Toyota hangs on to title of world's largest automaker for first half of 2013

General Motors and Ford can have all the success they please, but it doesn't seem like America's two largest manufacturers are going to topple Toyota in the first half of 2013. According to Reuters, Toyota moved 4.91 million vehicles in the first six months of 2013, representing a 1.1-percent drop from the same period in 2012.
GM is on the rise, though, with a four-percent increase in global sales, to 4.85 million. Volkswagen, still sitting in third, saw a 5.5-percent jump to 4.7 million vehicles in the first half of 2013.
If this pace continues for Toyota, it'll finish 2013 in the top sales spot for the second year in a row. The manufacturer fell to third, behind GM and VW, in 2011 after earthquakes and tsunamis ravaged its production capacity.
