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 Prius gets higher clearance, better suspension in Pakistan

It's been 16 years since the Toyota Prius launched in Japan. Finally, the world's most popular hybrid is becoming the first hybrid car to show up in Pakistan. This version of the Prius has been customized by Indus Motor Company (IMC) in order to deal with, well, let's just say some challenging road conditions. IMC knows what it's doing, and has modified Toyota and Daihatsu vehicles for the Pakistani market for over 20 years. The Prius brings with it the iconic shape and Parvez Ghias, CEO of IMC, told The Technology Times that the car's arrival, "is indeed a great milestone, not only in the history of IMC, but, of the entire nation." Pakistan Today says that IMC is beefing up the ground clearance of the imported Priuses and adds a "robust suspension system." Why would this be important? Well, the US Department of State warns travelers to beware of crowded roads, aggressive and poorly trained drivers and bad roads that could include potholes and sharp drop-offs. Then there's the "donkeys, cattle, horse carts, and even the occasional camel [that] can pose roadside hazards in some areas." There's also the big problem of terrorism-related violence in Pakistan, but we haven't heard that the Pakistan Prius has been bullet- and shrapnel-proofed.

Toyota ready to design more heart-racing Prius

Long praised for its fuel economy and reliability, the Toyota Prius has been no stranger to less-than-flattering remarks about its styling and sense of excitement. In fact, the model is a regular movie punchline. For evidence, see Mark Wahlberg in The Other Guys or, more recently, Ice Cube in Ride Along. Apparently, Toyota President Akido Toyoda is getting the message and is pushing for what's been translated as a more "heart-racing" design for both the Prius and the Camry, the Canadian website Driving says. The Camry and Prius accounted for about a third of Toyota's US sales last year. With the Camry as the best-selling US model for each of the last dozen years, Toyota US head designer Kevin Hunter noted at the Detroit Auto Show last week that the Japanese automaker is looking for a "more emotional" design for the boxy sedan. The Prius redesign may have more constraints, as aerodynamics have to be factored in to ensure top-line fuel economy for the world's best-selling hybrid. Toyota used the Detroit show to show off the FT-1, a concept that many consider a preview of the new Supra. How this "Future Toyota 1" will affect the Prius and Camry redesigns, whenever they appear, remains in question but we like where things are headed.
