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 issues multiple recalls for 6.4 million vehicles worldwide

It looks like 2014 may go down as the year of recalls. We were already at a record pace, and now it seems Toyota is recalling 6.39 million vehicles worldwide, including about 30 of its models for a variety of problems. None of the faults have caused any injuries or fatalities, but there have been two reports of fires caused by a defective engine starter motor.
Toyota's numbers show 1.772 million vehicles being recalled in the US, but that includes some overlap because the Yaris is being repaired for multiple faults. According to The Detroit News, there are 2.36 million affected models in all of north North America, 1.09 million in Japan and 810,000 in Europe, plus smaller numbers in other regions.
Among the vehicles recalled in the US are 1.3 million units of the 2009-2010 Corolla, Matrix and Tacoma, the 2008-2010 Highlander, the 2006-2008 Rav4 and 2006-2010 Yaris. The problem is that the driver's airbag module is attached via a spiral electrical cable. The connections on the cable can be damaged when the steering wheel is turned, which deactivates the airbag and causes the airbag warning light to come on. Toyota is replacing the cable with an improved part, but it's still making preparations to begin the repair. The company is sending affected owners notifications in the mail. According to The Detroit News, an unspecified number of Pontiac Vibe vehicles are also included in this recall because it shares the part with the Matrix.

Toyota recalling FJ Cruiser due to excessively bright headlights

Now, hold on. This recall isn't quite as serious as it sounds. Yes, Toyota is recalling 11,489 FJ Cruiser models from the 2007 to 2013 model years, and yes, it's because the vehicles, as the National Highway Traffic Safety Administration states, "fail to conform to Federal Motor Vehicle Safety Standard No. 108, 'Lamps, reflective devices, and associated equipment.'" But read the fine print and you'll see the catch: This recall is only for vehicles fitted with the automaker's auxiliary lighting kit that can be mounted to the front bumper.
Basically, the auxiliary lamp assemblies use 55-watt bulbs, and when these are turned on in conjunction with the upper beam headlamps, it's a pretty blinding sight. NHTSA states that excessively bright lights can blind other drivers, increasing the risk for a crash.
To remedy the situation, Toyota will replace the 55-watt bulbs with cooler 35-watt units. The recall is expected to begin later this month. Scroll down for the full details in the NHTSA report.
