Toyota FCV Concept comes one step closer to reality

When Toyota first conceptualized a gasoline-electric hybrid vehicle for mainstream Americans to drive, the initial response was pretty skeptical. Still, through relentless engineering and solid product after solid product, Toyota has built the Prius brand into the dominant force in the hybrid car market.
Something like that plan of attack is what the Japanese company is preparing for hydrogen fuel cell vehicles, as well, and that attack is seeing a critical salvo fired today with the debut of this FCV Concept at the Tokyo Motor Show.
Though there's nothing substantive to be said about rumors of a 300-mile range or a sticker price around $50,000, the FCV concept does offer a few technical details. The sharp-beaked concept makes use of two high-pressure hydrogen tanks and boasts a power output density of three kilowatts per liter.

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 says C-HR Concept is more of a Prius preview than we thought

When the designers thought they were just about finished with the new look of the fourth-generation Toyota Prius hybrid, higher-ups did not like what they saw and sent those designers back to the proverbial drawing board to come up with something a little spicier. Duly inspired, the designers came up with something last spring that may look a bit like the C-HR crossover concept, Automotive News says. For those looking for a Prius design with a little more bite, that isn't necessarily a bad thing. The C-HR hybrid concept isn't a direct preview of the new Prius, but the "diamond architecture" features like thick wheel wells and mean-looking grille could make an appearance on the hybrid. Those aren't exactly familiar Prius materials, but they may be coming to the next version of the world's most popular hybrid, whose production debut has been pushed back until the end of next year. It is also notable that there will likely be a far greater design difference between the standard Prius hatchback and the plug-in hybrid variant, which are pretty much identical in their current versions. The C-HR concept, whose look has been compared to that of the Nissan Juke, was unveiled at the Paris Motor Show last fall. We think it looks good, and wouldn't mind seeing some of the touches in the new hybrid.
