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.

Toyota FT-1 Concept presents a future we want to live in [w/videos]

Toyota has brought its A game to the 2014 Detroit Auto Show, showing off the striking FT-1 Concept. Short for "Future Toyota," the FT-1 is, we're imagining, the supposed Supra Concept we reported on early in December.
Penned by the Calty Design Research team, the FT-1 draws inspirations from the FT-HS and the Lexus LF-LC concepts from 2007 and 2012, respectively. We certainly see a bit of Lexus LF-A in the design, while there's more than a hint of Formula One in the FT-1's pointed nose.
"Our team was heavily influenced by Toyota's sports car past, especially Celica and Supra, and we sought to capture some of that history. It is an aggressive, track-focused sports car concept with a presence that has been amplified for shock and awe," said Alex Shen, Calty's Studio Chief Designer.

Toyota's Bob Carter says seat heater stop-sale due to inconsequential compliance error

Last week, Toyota let it be known that a number of its more-popular vehicles were subject to a "stop-sale" order due to faulty seat heaters on these vehicles. No injuries were reported, but the problem affected a lot of models, including the 2013 and 2014 Camry, Camry Hybrid, Avalon, Avalon Hybrid, Sienna, Corolla, Tacoma and Tundra. Toyota originally said 50,000 vehicles were involved, but Bob Carter, senior vice president of automotive operations for Toyota Motor Sales, knocked that down to 30,000 during an interview at the Chicago Auto Show this week and said that the problem is not going to have a big impact on Toyota's sales. "It's an important situation but it will have a very minor impact on February sales," he told AutoblogGreen. "Dealers will start receiving new heating elements this week and then we have a process to take out the heating element that was put in and exchange that for the new fabric. It's very simple. It's a quick repair." Quick in this situation means about three hours to swap out the heating elements in two seats, according to Toyota's John Hanson. Since the Avalon also has heated rear seats, that car will require a total of six hours in the shop. Hanson said there was no official timeline for when the exchange program would be completed, "but new vehicles are arriving at some dealerships with the new seat heaters already installed." With a fix already in place, Carter would not comment on whether a recall is likely, saying only, "I'm not the expert on that. We're working with the NHTSA and ultimately it's their decision. We believe it's an inconsequential compliance error that was made by one of our suppliers and we're going to correct it."
