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.

Car theft skyrockets thanks to rising parts prices

Cars and trucks today have achieved a high level of average quality, with safety and technology features that keep occupants safer than ever and meet consumers' high expectations. But the National Insurance Crime Bureau finds that those components come with a rising price tag, leading to expensive repair bills — and rising vehicle thefts to support a thriving black market for parts. The nonprofit NICB said it looked at the cost of replacement parts for the top 10 stolen 2016 models, with average OEM part prices pulled from a database of more than 24 million vehicle damage appraisals generated for 2016 and 2017 insurance claims. The list did not include major components like engines or transmissions, only easily-stripped components like bumpers, doors, hoods and headlights. It found that: The 2016 Toyota Camry, which had a used market value of around $15,000, had 15 commonly replaced parts that added up to almost $11,000, not including labor, with quarter panels alone costing almost $1,600 a pair and a set of alloy wheels tallying more than $1,600. The Camry was also the top stolen vehicle in 2016 at 1,113 thefts. A 2016 Nissan Altima had 14 standard parts worth more than $14,000, including a single headlamp assembly that costs just over $1,000. The Altima was the second-top stolen vehicle in 2016 at 1,063 vehicles stolen. And the 2016 GMC Sierra pickup, which was No. 7 on the 2016 top-stolen list, rang up $21,000 from 20 standard components, including an $1,100 headlamp assembly and an $1,100 rear bumper. "For the professional theft ring, stealing and stripping vehicles for parts has always been a lucrative business," Jim Schweitzer, NICB's senior vice president and chief operating officer, said in a statement. "On today's cars and trucks, the parts are often worth more than the intact vehicle and may be easier to move and sell. That's why we see so many thefts of key items like wheels and tires and tailgates ... there's always a market for them." Check out the NICB infographic below. Vehicle thefts in the U.S. rose by more than 4 percent in 2017, based on preliminary FBI data, after rising 7.6 percent in 2016, though the overall trend has been down since vehicle thefts peaked in 1991, according to the NICB.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.
