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 brings TRD Griffon GT86 to Goodwood [w/video]

In the midst of the 2013 Goodwood Festival of Speed, there's a particularly special Toyota running up the hill. This special entry is a GT86 (the cousin to our Scion FR-S and Subaru BRZ) that's been poked, prodded, and tweaked by the minds at Toyota Racing Development. The result of TRD's fettling is a nearly race-ready car.
Starting with the body, the hood, doors, trunk lid, and wings are all made of carbon fiber. The lightweight treatment doesn't end there, though. The bumpers, fenders, and diffuser all feature carbon-fiber-reinforced plastic, while the windows are now made of polycarbonate plastic.
Under the hood sits the same 2.0-liter boxer engine found in the standard GT86, but its six-speed manual gearbox features a shorter final drive ratio for improved acceleration. The coilover suspension has been firmed up, and a TRD mechanical limited-slip differential replaces the Torsen unit. The TRD Griffon rides on TWS 18-inch wheels and Yokohama Advan tires. To bring proceedings to a stop, TRD has fitted its own mono-block caliper kit, complete with more robust racing pads.

Toyota says no one wants a Toyota electric car

It's no secret that Toyota doesn't really have a heart in pushing pure electric vehicles. The very limited Scion iQ EV project was killed before it went very far and the RAV4 EV project with Tesla was always only meant to produce just 2,600 units, but it didn't even get that far. In short, by all public appearances, Toyota just doesn't see the value of a pure EV. "No one is coming to our door asking us to build a new electric car." – Toyota's Craig Scott Toyota's public reasoning for the lack of a Prius C EV, for example, has often been that customers don't want to compromise on range and that hydrogen is a better bet. Company executives like Bob Carter say so over and over again. A new comment by Craig Scott, Toyota's national manager of advanced technologies, says that the Japanese automaker, give a slightly different spin on things. "Toyota actually favors fuel cells over other zero-emission vehicles, like pure battery electric vehicles," he told the Los Angeles Times. "We would like to be still selling cars when there's no more gas. And no one is coming to our door asking us to build a new electric car." This, understandably, has riled up a lot of EV supporters, many of whom have called on all automakers to sell more electric vehicles. After all, if Nissan can sell around 3,000 EVs a month in the US, couldn't Toyota do something similar? Are there thousands of people coming to the door asking for the fuel cell sedan that Toyota will start selling in the US next year? That answer is unclear, but it certainly doesn't look like Toyota is backing off its H2 bet any time soon.
