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 Recalling Millions Of Cars Over Multiple Concerns

Toyota Motor Corp. is recalling nearly 1.8 million vehicles in the U.S. for various safety problems, including air bags that may fail to deploy. The Japanese automaker announced the U.S. recall Wednesday as part of a broader recall of 6.39 million vehicles - and 27 Toyota models - globally. In the U.S., the recall includes: - 1.3 million vehicles with faulty electrical connections that could cause the air bags to deactivate. Included are the 2009-2010 Corolla, 2009-2010 Matrix, 2008-2010 Highlander, 2009-2010 Tacoma, 2006-2008 RAV4, 2006-2010 Yaris and 2009-2010 Pontiac Vibe. If the air bags deactivate, they could fail to deploy after a crash. - 472,500 small cars with defective springs in the front seat rails, which could prevent the seats from locking in place. Included are the 2006-2010 Yaris hatchback, 2007-2010 Yaris sedan and the 2008-2010 Scion XD. Toyota said it is currently working on remedies for the problems. Dealers will replace the defective parts for free when replacement parts are available. The Pontiac Vibe, which is made by General Motors Co., is included in the recall because Toyota designed and engineered it for GM when the two companies shared a factory in California. GM says 40,500 Vibes will be recalled, and says GM dealers will make repairs when Toyota sends them the parts. The air bag issue is unrelated to a separate GM recall of 2.6 million vehicles for an ignition switch defect that can also deactivate the air bags. The Vibe isn't included in that recall. Toyota said no injuries or crashes have been reported related to the recalls. By region, the recall affects 2.3 million vehicles in North America, 1.09 million vehicles in Japan and 810,000 vehicles in Europe. Other regions affected by the recall include Africa, South America and the Middle East. The recall is one of Toyota's largest since 2009 and 2010, when the company issued a series of recalls totaling more than 10 million vehicles for various problems including faulty brakes, sticky gas pedals and ill-fitting floor mats. Toyota is under pressure to announce recalls quickly after a U.S. government investigation found it hid information about past defects. Last month, the company agreed to pay $1.2 billion to settle that investigation. It also paid fines totaling $66 million to the U.S. government for delays in reporting unintended acceleration problems.

eBay Find of the Day: Harley-Davidson powered Toyota Prius [w/video]

Sometimes we pluck cars from the listings of eBay Motors because they're old and interesting, some for being simply lovely, some for rarity and some for pure fun. And sometimes we pick eBay Finds of the Day, because they're hacked apart Toyota Prius' with Harley Davidson V-twin-power; concocted by the same mind that brought you innumerable Jalopnik articles and is partially responsible for the joy that is the 24 Hours of LeMons. This time it's that last one.
A fairly subtle tweet from long-time Jalop contributor and well-regarded grease monkey, Murilee Martin, hipped us to this crazy Frankenstein Prius. Built from the bones of a 2008 Toyota and the heart of a 1986 Harley-Davidson Sportster 883, the motive portmanteau is, well... it's a thing.
Toyota's advanced Hybrid Synergy Drive has been unceremoniously wrenched and snipped out of the engine bay, making room (via an artful hole in the hood) for the towering, bored out V-twin. Or, as the maestro himself puts it:
