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.

Renault Scenic EV takes first place as (European) Car of the Year

The automobile awards season may not be over, but two of the more prestigious annual races came closer to a climax this week. One might need a scorecard to keep track. We’re focused here on two events: the World Car of 2024, now reduced to three finalists in six categories. Then thereÂ’s the Car of the Year, known in some quarters as the European Car of the Year. Except that the car doesnÂ’t have to be European to win, only sold there. Got that? Winners out of the way first: At the Geneva Motor Show on Monday, the Renault Scenic E-Tech all-electric has been voted Car of the Year 2024. The Scenic is a fairly compact, somewhat stylish SUV for Europe only, and is the seventh vehicle from the French brand to win the award. It sells in the United Kingdom for about $47,500. The other six finalists that had made the first cut of voting in November were the BMW 5 Series, BYD Seal, Kia EV9, Peugeot E-3008/3008, Toyota C-HR, and Volvo EX30. The trophy winner was chosen by a jury of 59 motoring journalists from 22 countries. Scenic came in first place with 329 points. The Seal was the first Chinese-made car to make this awardÂ’s shortlist; it finished sixth out of seven, just up from the Toyota. One judge explained his decision to grant the Seal zero votes. Writing in Top Gear, Paul Horrell wrote this entertaining critique: “It looks good and is well specified, so makes a strong market entry. The advanced electric system and cobalt-free battery are commendable too, and it's enjoyable enough to drive quickly. That's undermined by an agitated ride over bumps, and the logic of screens and switches is pretty eccentric.” Recapping the World Car of the Year 2024 update, the sponsors shared the stage at Geneva on Monday with the Europeans as well, although they revealed only the top three finalists in six categories. For the ultimate prize, they are the Kia EV9, the Volvo EX30 and the BYD Seal. The winners will be announced March 27 at the New York International Auto Show. Here's more on the World Car finalists.

Japan plans real-world diesel emissions test after companies fail

Japan's transport ministry plans to start real-world diesel emissions tests after an experiment found four models from Toyota, Nissan, and Mitsubishi that produced more nitrogen oxide (NOx) emissions than the nation's rules allow, according to The Japan Times. Regulators there usually only perform emissions checks in the lab. The VW diesel scandal has everyone double-checking their figures. Diesel versions of the Toyota Hiace van, Land Cruiser Prado, and Nissan X-Trail produced up to 10 times more NOx than allowed. The Mitsubishi Delica D:5 was up to five times over the limit, The Wall Street Journal reports. There was no evidence of defeat devices in the vehicles. Mazda performed well in the experiment, though. The CX-5 passed with nearly the same results on the road and in the lab. The Demio, better known as the Mazda2, did nearly as well with only slighter higher figures in the real world than in the controlled setting. The experimenters theorized the reason for the excessive emissions was that cold weather caused the engines' software to shut off the exhaust gas recirculation to prevent damage, according to the WSJ. However, this behavior also increased NOx production. Toyota, Nissan, and Mitsubishi don't have to worry about punishment from the transport ministry because this check was just an experiment. Their models already passed the mandated lab tests, which was the only requirement, according to The Japan Times. As governments begin greater real-world emissions tests, the results suggests diesels aren't very clean. A recent check in France found models from Ford, Renault, and Mercedes-Benz that didn't perform up to the standards. Regulators in India conducted similar evaluations and ordered VW to recall over 300,000 vehicles. Related Video:
