How Toyota's 100-year textile history influenced FCV hydrogen fuel cell car

Turns out, Toyota had a surprising ace in the hole when it came to building the new fuel tanks for the FCV hydrogen fuel cell car, which is coming next year. Well before Toyota became the Toyota Motor Company, it was the Toyota Industries Corporation and it made textile looms. This is important because the main structure of the hydrogen tank is wound carbon fiber. When Toyota set out to increase the strength of the tanks to hold hydrogen stored at 10,000 psi (up from 5,000 in the previous tanks), it was able to draw on its 100-year-old history as it designed its car of the future. "A lot of that textile experience came back when we did the tank wrapping." – Justin Ward "We have a lot of experience with textiles," Justin Ward told AutoblogGreen at the 21st World Congress on Intelligent Transport Systems (ITS) in Detroit this week, "and a lot of that textile experience came back when we did the tank wrapping." On top of being able to hold the higher-pressure hydrogen, Toyota's first attempt to build its own hydrogen tank was six times faster than the industry standard, so it saved time and money as well as working better. The company will also be able to inspect its own tanks. Ward is the general manager of powertrain system control at the Toyota Technical Center and hydrogen vehicles are something he knows a lot about. The reason for the stronger, 10,000-psi tanks is because the 5,000-psi tanks only offered around 180-200 miles of range, even with four tanks in the early $129,000 FCHV Highlander hydrogen prototypes. The FCV only has two, but they will able to deliver the 300-mile range that customers told Toyota they wanted. Dropping the number of tanks not only obviously reduced the cost for the tanks themselves but also the number of valves and hoses and other components you need. Despite the benefits of higher compression, going much higher doesn't make sense. 10,000 psi is the "natural progression," Ward said, because "you start to bump up against compression inefficiencies." Think of an air compressor. When hydrogen is produced at a wastewater treatment plant or a reforming site, Ward said, is it at around ambient pressure (14 psi). That has to be raised, using compressors, all the way to 10,000 psi. "That takes energy," Ward said, "and every doubling of pressure adds another doubling of energy needed, so it starts to add up pretty fast if you go too high." Component specifications are also fine at 10,00 psi, but more difficult at higher levels.

Toyota temporarily idles pair of Indian plants due to labor unrest

The Detroit News reported today that Toyota will restart production at two Indian plants, following a shutdown on Monday.
Factory labor, management and police in Asia engage in the kind of violent altercations that we're not used to, having almost entirely walked away from the overtly brutal relations epitomized by the Pinkerton Detective Agency and the Flint Sit-Down Strike. In India, a plant owned by a Ford transmission supplier plant was shut down in 2009 after incidents between workers and armed men around the same time as Ssangyong workers occupied a factory in South Korea, in 2012 Suzuki Maruti workers rioted over wages around the same time upset employees beat a ceramics factory president to death in retaliation for a labor leader's killing.
Toyota is the latest to company trying to avoid that road. The Detroit Free Press reported earlier this week that it shut down two plants in India after 11 months of acrimonious wage negotiations and arbitration have gone nowhere. Toyota said the plant workers in Bidadi, near Bangalore, had deliberately stopped production at times over the past 45 days and threatened management. The workers said they wanted their wages raised by an amount already agreed to by management, but that management had reneged; news reports weren't clear on the amount, some saying nearly 10,000 rupees ($165 US) more per month, another saying 4,000 rupees ($65 US), but reports agree that Toyota has said it will only go as high as 3,050 rupees ($50 US).

Toyota, Ford and Honda again top Consumer Reports Car-Brand Perception Survey

Consumer Reports has released its annual Car-Brand Perception Survey, and the list looks awfully familiar. The top six brands are identical to last year's results, with Toyota, Ford and Honda continuing to occupy the podium. All told, Toyota walked away with 133 points, putting it 15 ahead of second-place Ford. Honda jumped 26 points this year, narrowing Ford's lead to just four points in total.
Consumer Reports polls buyers from across the country on how they see multiple brands in seven categories, including quality, safety, value, performance, design/style, technology/innovation and environmentally friendly/green. Researchers then combine the findings to come up with the total brand score.
While value and performance remain important to buyers, CR found quality and safety are still on top when it comes to significance. Scion and Mitsubishi found themselves at the bottom of the pack with the worst score of all, tied at just six points. Ram, Fiat and Mini filled out the lowest five with scores of seven, eight and 10 points, respectively.
