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.

2014 Toyota Aygo is so cross with itself

It almost made it, but images of the redesigned Toyota Aygo have leaked ahead of its official debut at tomorrow's Geneva Motor Show. The new Aygo sports an aggressive look overall with a, um, mark on its face.
That distinguishing design feature aside, we quite like the angular headlights and muscular overall look of this little city car. The gaping trapezoidal air intake make the Aygo look more substantial, while swollen rear wheel arches hint at something sportier than your standard commuter device.
Sportiness, though, isn't likely to be a big part of the Aygo. As it's built on the same platform as the Citroën C1 and Peugeot 108, we should expect the same pair of gas-powered engines, which means at best, the Toyota will come to market with 82 horsepower under hood.

Will Toyota lose up to 70% of its workforce in TX relocation?

Toyota's decision to move its US headquarters from its longtime home in Torrance, CA, to Plano, TX, was one of the biggest stories in the automotive industry this spring. With several months since the announcement, more details about the plan have leaked out. It seems that pulling up stakes could mean an even larger shakeup in the Toyota workforce than first thought.
According to Automotive News, Toyota intends to hang onto around 50 percent of its workforce in the move to the Lone Star State. However, even that figure might be optimistic. According to an unnamed insider speaking to AN, there is a fear the actual number could be closer to 30 percent. For comparison, Nissan retained about 42 percent of its workers in its move from California to Tennessee.
The actual percentage making the move is a mystery because Toyota is still rewriting its job descriptions under a single set of guidelines. The changes affect benefits, bonuses and the reporting structure, according to Automotive News, and employees' reactions could play a big role in who decides to go. According to an unnamed worker speaking to AN, the wait is hurting morale. Some people are even applying at the nearby Honda headquarters.
