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.

Japanese dealer petitioning Lexus for luxury van [w/poll]

Used to be that if you wanted a luxury automobile - especially one to be chauffeured around in - your choices were basically limited to a sedan. It could be bigger or smaller, more or less expensive, depending on your needs and budget, but it was always going to have four doors and a trunk. But these days the rich and famous are looking elsewhere for their commodious forms of pampering transportation. There are, of course, the crossovers and SUVs, which only seem to be getting bigger and more expensive thanks to the likes of the Mercedes-Benz G-Class, Range Rover L and upcoming Bentley sport-ute. But luxury vans are becoming the new big thing.
That's the point that one dealer in Japan is trying to make to Toyota. The dealership owner himself reasons that if he's going out on the town, he's likely to take his chauffeured Lexus LS. But if he's taking a few friends along, even the biggest sedan isn't going to cut it. So he takes a Toyota Alphard (pictured above, also known as the Vellfire), a JDM van that's even bigger than a Voxy/Noah or Sienna but hardly a high-end affair. That's why he's asking Lexus to make a luxury van.
The idea may seem a little far-fetched, but isn't without precedent. It didn't take much for Lexus to transform the Land Cruiser into the LX and thus create its first luxury SUV. And as Mercedes has shown with pimped-out versions of the Sprinter and now with the debut of the new V-Class in Geneva, there's clearly a market for it... in some countries, anyway. The only question in our minds is how long it's going to take other luxury automakers to catch on, because let's face it: the Chrysler Town & Country ain't gonna cut it for those used to be driven around in a Maybach.

Toyota working on cars that hover above the roadway

Toyota is one of the largest automakers in the world, but it's not content simply building and selling conventional cars - it's been at the forefront of numerous advancements in ground transportation. It is widely credited with advancing the cause of hybrid propulsion, and alongside Audi and Google, is among the first automakers seriously testing self-driving cars. We could go on, but the news here is that Toyota is reportedly developing vehicles that hover above the road surface instead of rolling along it.
The news comes from Hiroyoshi Yoshiki, one of Toyota's tech gurus, who revealed at Bloomberg's Next Big Thing summer in San Francisco that the company is working on hovering cars - ones that travel just above the road surface, but don't actually fly in three-dimension space.
According to The Verge, a spin-off of our own sister-site Engadget, Yoshiki refused to elaborate on what the project entails and how far along it is. He was speaking along acting NHTSA chief David Friedman, who lauded such advancements as a "great taste of innovations to come," but stressed the significance of more concrete improvements to conventional automobiles - like inter-car communications to keep vehicles from colliding on the highway - as more relevant to today's industry.
