Japan carmakers vouch for safety of some Kobe Steel parts

TOKYO — Four Japanese automakers on Thursday said they found no safety issues with aluminum parts supplied by Kobe Steel Ltd, allaying some concerns that falsified quality data on products from the steelmaker had compromised their vehicles. Kobe Steel shares surged after the car makers' statements, but the steelmaker still has to contend with a U.S. Justice Department probe, while checks continue at hundreds of companies involved in complex supply chains spanning the globe. Japan's third-biggest steelmaker admitted earlier this month it falsified specifications on the strength and durability of aluminum, copper and steel products, along with materials for optical disks. The falsifications stretch back for more than 10 years, a senior executive told Reuters this week. Since then, global automakers, aircraft companies and other manufacturers have scrambled to identify potential hazards in their products. Toyota, Honda, Nissan and Mazda said that hoods and other exterior parts used in their cars which were made from aluminum directly supplied by Kobe Steel were safe. Kobe Steel shares ended the day nearly 7 percent higher but are still down by more than a third since it announced the data falsification. Automakers are still making checks on other parts, including those that they received through their parts suppliers. "We confirmed that the materials satisfy applicable statutory standards, and our own internal standard, for key safety and durability requirements for vehicles," Toyota said in a statement. Toyota, one of the world's largest automakers, identified aluminum plates supplied by Kobe Steel for the hoods and rear hatches of Toyota and Lexus brand vehicles. Though outside the automaker's specifications, they were still safe to use. While Subaru and other carmakers said they were still investigating the issue, the announcements by Toyota, Honda, Nissan and Mazda suggest that Kobe Steel's cheating scandal may have a limited impact on product safety."SERIOUS SITUATION" Nonetheless, the company's fate hangs in the balance while checks are being carried out. It must report to Japan's industry ministry by around the end of next week on any safety concerns and provide a more extensive account of the problems a fortnight later. Industry leaders have reached a consensus that Kobe Steel is in a "serious situation," a senior Japanese manufacturing executive told Reuters.

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 giving away its first hydrogen car in US

California isn't Nevada, but Golden State residents are nonetheless being given a chance to make a small bet on what may be a large prize, courtesy of Toyota. The Japanese automaker will start selling its first hydrogen fuel-cell vehicles on the West Coast late next year, and before that, Toyota would like to pick up some positive publicity by giving America's first one away to one lucky Californian. Toyota is working with the Environmental Media Association, a nonprofit that melds celebrities with sustainability-related causes, on the promotion. The upshot is that folks can go to Bidding For Good and buy a $100 ticket to be eligible for the prize. Heck, people can get a half-dozen ducats for $500. What a deal. The winner will be announced October 18 at Warner Bros. Studios. Last month, Toyota unveiled a television commercial that proclaimed 2015 as the potential turning point for fuel-cell vehicle adoption. Toyota will start selling the FCV in Japan next April for about $69,000. Toyota says the fuel cell vehicle will be able to go about 300 miles on a full tank of hydrogen and, aside from some water vapor, will not have any emissions.

How the West Was Won: Toyota Offers Chance to Be a Fuel Cell Pioneer TORRANCE, Calif., Oct. 8, 2014 – It's hard to be a trendsetter in places like Los Angeles or San Francisco, but one lucky Californian will blaze that trail when they park a new Toyota Fuel Cell Vehicle (FCV) in their garage. Toyota and the Environmental Media Association (EMA) are offering a historic opportunity to own the company's first zero-emission hydrogen vehicle when it arrives in California in late 2015. Toyota is the first major auto manufacturer to give away a fuel cell vehicle to an individual owner. As the infrastructure to support the vehicle is currently only available in the golden state, prize applicants must be California residents. Residents can purchase opportunities to win at www.biddingforgood.com for a cost of $100 per ticket or $500 for six. All monies raised will benefit programs of the EMA, a nonprofit 501(c)3 dedicated to harnessing the power of celebrity and the media to promote sustainable lifestyles. The winner will be announced at the 24th annual EMA Awards, presented by Toyota and Lexus, on Oct. 18 at Warner Bros Studios. The EMA awards honor individuals within the entertainment industry for efforts to promote environmental messages.
