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.

Autoblog Minute: VW Q3 financial woes, 2015 Tokyo Motor Show

Consumer Reports pulls its Tesla recommendation, the U.S. Copyright Office offers a ruling affecting car owners, VW gets hit hard with third-quarter losses, and lots of exciting news from Tokyo. Autoblog senior editor Greg Migliore reports on this edition of Autoblog Minute Weekly Recap. Show full video transcript text [00:00:00] Consumer Reports pulls its Tesla recommendation, the U.S. copyright office offers a ruling that affects car owners and gear heads, VW gets hit hard with third-quarter losses, and lots of exciting news from Tokyo. I'm senior editor Greg Migliore and this is your Autoblog Minute Weekly Recap. After a week away testing vehicles for Autoblog's Tech of the Year award, we're back in the office to recap the week in automotive news. [00:00:30] One of the things you might have missed was Consumer Reports pulling its recommendation of Tesla's Model S sedan. The blemish for Tesla comes after a tally of reviews from customer surveys. The most common problem areas for the Model S as cited by survey takers included: the drivetrain, power equipment, charging equipment, body and sunroof squeaks, rattles, and leaks. So lots of stuff. Though they could not ignore a score of "worse-than-average", Consumer Reports still [00:01:00] highlighted the fact that the Model S was "the best performing car" they've ever tested. Telsa CEO Elon Musk took to social media to defend his sedans saying: "Consumer Reports reliability survey includes a lot of early production cars. Already addressed in new cars." And, "Tesla gets top rating of any company in service. Most important, CR says 97% of owners expect their next car to be a Tesla (the acid test)." In Financial news, Volkswagen took a hit and reported an operating loss of [00:01:30] $3.84 billion. This is the first such loss for VW in 15 years. Toyota reclaimed the crown as the world's largest automaker as well. It's important that it's not all doom and gloom for VW though in Q3. Sales revenues were up and the company's automotive division boasts $30 billion dollars in liquid assets. It's a sizable war chest that will no doubt come in handy, as the company has yet to feel the full brunt of the diesel emissions scandal. Good news for gear heads. The US copyright office [00:02:00] ruled in favor of mechanics and car owners by granting an exception to existing copyright law. The law was originally meant to prevent software pirating and bootlegging of Hollywood movies.

No diesels in the running for 2016 Green Car Of The Year

It's a new era for the Green Car Of The Year. In the past, the theme of the award was to take a broad look at alternative powertrains and pick the best among them. "Clean diesels" from the Volkswagen group were often among the finalists and won the award twice. For the 2016 edition - which will be handed out at the LA Auto Show next month - not a single diesel made the list. There's little wonder why. Green Car Journal, which names the winner with a panel of experts, had to strip two VW brand vehicles of their past wins. The 2009 VW Jetta TDI, which won in 2008, and the 2010 Audi A3 TDI, which won in 2010, have both lost their titles now that the world knows about the "defeat devices" that VW installed in many of its TDI vehicles around the world. So, what does that leave us with for 2016? Two plug ins, a hybrid, and two gas vehicles. The two electric vehicle are the Audi A3 e-tron and the Chevy Volt, while the all-new Toyota Prius (which will come with a plug-in version later) is the lone pure hybrid. Rounding out the pack are two efficient gas models: the Hyundai Sonata and the Honda Civic. This is the tenth year for the Green Car Of The Year, and it will be interesting to see if diesels can come back into the award's good graces (for the record, no diesels were among the finalists in 2013, either) in the future. For now, we'd like to know who you think should win. You can read more about the finalists in the press release below and then cast your vote in our poll.
