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, Honda, Mazda and Nissan recall 3.4 million vehicles for faulty airbags

Most vehicle recalls that take place these days are a result of some problem that happens during the manufacturing process by the automaker, but as we see here, parts suppliers can also factor in to problematic safety issues. Automotive News is reporting that a total of 3.4 million vehicles produced by Japanese automakers between 2000 and 2004 are being recalled globally due to faulty airbags produced by an outside supplier, Takata Corp.
According to the report, vehicles from Toyota, Honda, Nissan and Mazda are being recalled because of passenger front airbags that do not inflate properly. Globally, Toyota is said to be recalling around 1.73 million cars including 510,000 in the US composed of Toyota Corolla, Matrix, Sequoia and Tundra as well as the Lexus SC430 for the 2001 through 2003 model years; this is the second time this year the 2003 Corolla and Matrix have been recalled for an airbag problem. Honda is recalling 1.14 million models, Nissan another 480,000 and Mazda 45,463. The article says that Takata supplied faulty airbags to non-Japanese automakers, but it did not specify which ones.
Honda and Toyota have released information on their own websites about the recall, while Nissan and Mazda have not yet commented. Read official press releases from Honda and Toyota, below, and look for updates as we have word from the others.

Toyota's refreshed Sai is a Lexus HS by any other name

Toyota first launched Lexus in the United States back in 1989, but it wasn't until 2005 that it brought the luxury marque home to roost. But don't think that Toyota didn't find a way of selling many of its premium models in the Japanese Domestic Market in the meantime. The Lexus LS was sold as the Toyota Celsion, the ES as the Vista and Camry Prominent, and the SC as the Soarer. (We could go on, but you get the point.)
These days Lexus sells in markets around the world, including Japan, but Toyota still spins off its own versions of Lexus models to sell domestically as well. Like the new Sai, for example. Sharing its platform, hybrid propulsion and much more with the Lexus HS (which you may remember as the world's first dedicated luxury hybrid until it was pulled from the market early last year), the Sai was introduced to Japan at the same time as the HS was rolled out around the world. Now nearly four years on the market, Toyota has given it a bit of a refresh.
Boasting a far more aggressive front end and a restyled rear, the revised Sai features LED headlights, 16-inch alloys and a higher-quality interior in which JDM buyers will find a new center console and trim, along with an optional 10-speaker infotainment system. Toyota also boasts that the new Sai is made of 20-percent Ecological Plastic and recycled resin.
