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.

How new car shortages may impact your buying experience

If you want further proof that the auto industry is bouncing back, look no further than the empty lots and forecourts of your local dealership. According to a story by The Wall Street Journal, continued high demand for mainstream cars is overtaxing automakers' ability to produce enough models. Several dealers interviewed for the story are reporting two-week supplies as opposed to the typical two-month allocations.
With sales expected to hit 1.4 million units when August numbers arrive shortly and incentive spending down to its lowest amount since January, these limited supplies are pushing prices even higher. For example, according to the WSJ, the average price of a Ford Fusion is up past $26,000. Unfortunately, it's difficult for manufacturers to increase production quickly. If it invests in its facilities, as many manufacturers have done, it risks wasting cash if growth suddenly slows. At the same time, the momentum gained over the past several years could be short lived if vehicle supplies continue to dwindle. "Manufacturers are in a precarious situation," notes Karl Brauer, a senior director at Kelley Blue Book.
Low interest rates and a wealth of desirable features are also allowing customers to purchase more expensive vehicles while justifying their higher overall price tags, a situation that is compounding supply shortages. Even now, during the annual end-of-summer clearance season, deals on new vehicles are remarkably difficult to come by. According to the report, the Toyota Corolla is in a self-inflicted state of shortage, as Toyota clears out inventory in anticipation of the new 2014 generation arriving in dealers. Ford's supplies should rebound as Fusion production comes on line at its Flat Rock, Michigan factory. The Chevrolet Impala, Honda Odyssey, Civic, and Accord and Subaru Forester are also facing shortages.

2019 Toyota Corolla Hatchback, Volvos earn IIHS Top Safety Pick rating

It's time for another round-up of recent IIHS crash tested cars. The trio this time include the 2019 Toyota Corolla Hatchback, 2019 Volvo XC90 and 2018 Volvo S90. All three have earned one of the highest ratings from the IIHS, the Top Safety Pick. And all three continue a trend of very safe cars having slightly below-par headlights, preventing them from earning the highest Top Safety Pick+ rating. Of these three cars, the Corolla Hatchback has the most impressive scores. It earned the highest "Good" rating in every single crash test, including the difficult small-overlap passenger-side collision. It also received the top score for access to LATCH anchors for child seats. The standard forward collision prevention technology also brought home the best score possible, stopping the car before a crash at speeds up to 25 mph. The headlights themselves weren't particularly bad either, earning the second-highest score of "Acceptable" with both the standard and optional LED headlights.

Both Volvos shared similar scores to the Corolla Hatchback, with "Good" ratings for all crash tests they participated in, and top rank for their standard forward collision technology. Both vehicles were not tested for the passenger-side small overlap collision, so there is no score in that area. Both also received the "Acceptable" rating for LATCH anchor access. In the headlight department, the XC90 earned "Acceptable" scores for both of its available headlights, and the S90 received an "Acceptable" for its optional lights, while the standard ones were rated as "Marginal."
