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 headed to New York with 2014 Highlander, revised Scion tC

Toyota has given us a look at what the company will bring to the 2013 New York Auto Show. Visitors will get to set their eyes upon the all-new 2014 Highlander, and while the automaker isn't saying much in the way of details, we do get the teaser you see above (click to enlarge) to ponder on until next week. The image shows little more than a headlamp and a bit of grille, but gives us the flavor of what the crossover will bring to the table.
Scion, meanwhile, says it plans to dust off the "new 2014 tC sports coupe." While we don't imagine the two door will have undergone a major surgery, we're interested to see what the automaker has cooked up. The tC last endured a redesign in 2011. Check out the brief press release below and look for the vehicles to bow on March 28.Y

Question of the Day: Ever consider driving a minivan?

Since I'm supposed to know something about cars, it happens all the time: friends and relatives ask me advice about what kind of vehicle they should get. Very often, the only type of vehicle that can check every item on their wish list (e.g., hauls lots of people and stuff, gets good fuel economy, has great crash-test ratings, can take four Great Danes camping, and so on) is a modern minivan... and, of course, nobody wants to hear this. I'm not a minivan person, they will wail, and so they end up with a cramped, fuel-swilling SUV or a not-so-space-efficient minivan-in-disguise CUV. So, is it worth becoming one of those minivan people in order to get the incredible usefulness of these masterpieces of vehicle engineering, or do you hold your head high and drive something that doesn't quite meet your needs?
