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 recalls 4,000 Tacoma pickups over valve springs

When you build as many cars and trucks as Toyota does, you're bound to run into the occasional recall. In the past month alone, the Japanese auto giant has recalled over 800,000 Camry, Avalon and Venza models over problems with the air-conditioning units, and 10,000 more before that over windshield wiper issues. Now Toyota has issued another recall notice, but this time for far fewer vehicles.
The recall revolves around the engine valve springs in the 2013 and 2014 Tacoma, specifically those fitted with the standard 2.7-liter four-cylinder engine and not the optional 4.0-liter V6. The issue is that the valve springs are prone to cracking and breaking over time, and results from improper maintenance of the manufacturing equipment used by one of the two suppliers that outfit Toyota with the components in question.
All told, some 4,000 vehicles will be subject to the voluntary recall, the owners of which will receive notice by mail. If you think that could be you and want to get a jump on the problem, you can read the announcement below and call Toyota yourself.

Scion testing updated FR-S

It looks like Toyota is preparing a mid-cycle update for its critically acclaimed GT86, known here in the US as the Scion FR-S or Subaru BRZ. As far as updates go, this one looks to be rather average. Hidden behind the camouflaged front and rear ends, we have new headlights and taillights, which according to our spies looked to be of the LED variety. We wouldn't be shocked to see the GT86 get LED taillights, although fitting the top-of-the-line headlights seems less likely. Supporting that position are the images we have of the actual headlights in action, which don't look quite bright enough to be full LED units. Instead, we'd expect some new form of running light, perhaps with bi-xenon low beams. Aside from the lamps, the front bumper gets a larger, more prominent lower intake, while the rear end sports a redefined bumper that houses larger dual exhaust tips. The size of the spoiler has been increased, too. According to our spies, we should also expect powertrain enhancements – which we can only hope means more power – as well as upgrades to the interior of the GT86. While it's possible that the updates being tested in Germany could be exclusive to the European market, that seems unlikely. We'd expect the same new enhancements to at least find their way to the Scion, if not its Subaru-badged twin. Check out the full battery of spy photos up top. Related Video:
