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.

NACTOY winners, and driving the Genesis GV60, Polestar 2, Mercedes-AMG GLS 63 | Autoblog Podcast #813

In this episode of the Autoblog Podcast, Editor-in-Chief Greg Migliore is joined by Senior Editor, Electric, John Beltz Snyder. This week, we discuss the North American Car, Truck and Utility of the year winners: The Toyota Prius, Kia EV6 and Ford Super Duty (and Greg explains his votes). In other news, we talk about GM offering $7,500 incentives for EVs that lost their tax credits, another possible calendar change for the Detroit Auto Show and Stellantis potentially scaling back its auto show presence. Greg spent his winter break with the Genesis GV60 and Polestar 2, while John has been driving the Toyota Prius Prime and Mercedes-AMG GLS 63. Finally, they take to Reddit for this week's Spend My Money question, and pick a sedan under $6,000. Send us your questions for the Mailbag and Spend My Money at: Podcast@Autoblog.com.

Toyota Aygo X-Wave pops its top

Chop the top off a car and you'll let the sunshine and warm air in, but you'll also get a car that's heavier, less rigid and costlier. That's why European hatchbacks in particular have been increasingly favoring retractable fabric roof panels that keep the structural integrity in tact while letting the sunshine in. The Fiat 500C, Citroen DS3 Cabrio and Renault Twingo all offer this type of setup – as do the Peugeot 108 and Citroen C1, and now their Toyota platform-mate is following them down the same path. Recently announced in the UK is this Toyota Aygo with X-Wave roof option. It's a black canvas panel that opens up the space above both rows of seats at the push of a button. Unlike the roofs on some of the other aforementioned European city cars, it doesn't extend all the way down to the base of the back window, but that just means it doesn't stack up and impede cargo space and rearward visibility. Toyota is bundling the X-Wave roof option with additional equipment like upgraded lighting, infotainment system and alloys for GBP895, taxes included (equivalent to $1,355 at today's exchange rates). That's a lot less than Fiat, for example, gets for upgrading from a 500 to a 500C on either side of the Atlantic. It's also even less than Peugeot and Citroen charge for similar options on their versions of the same vehicle in the UK, and that strikes us as a pretty cost-effective way to go motoring with the top down. LESS METAL, MORE FUN WITH AYGO'S X-WAVE OPEN TOP OPTION How do you make driving a Toyota Aygo even more fun? One sure-fire way is to provide some classic open-top enjoyment with a new retractable x-wave canvas roof. Looking ahead to longer, warmer days, Toyota has launched the x-wave as an option on the five-door Aygo x-pression model. Finished in black, the roof is factory fitted and is full length, ensuring that anyone travelling in the rear seats also gets to enjoy some of the wind-in-the-hair experience. The roof is electrically operated, using a simple switch next to the map light control in the headlining. Specifying the x-wave adds even more appeal to the Aygo x-pression, which also features 15-inch alloy wheels, front fog lamps, projector headlights with LED daytime running lights, the x-touch multimedia system with DAB and Bluetooth, reversing camera and air conditioning.
