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.

New Toyota 86 and Subaru BRZ could move to a Toyota platform

There's more rumormill news about the future of the Toyota 86 and its twin, the Subaru BRZ. Australian website CarSales reports that the next versions of the coupe twins may switch from the existing and heavily modified Impreza platform to Toyota's TNGA platform. The reason? An unnamed Subaru insider tells the site the next-generation versions of the cars will retain their rear-wheel-drive configuration and thus won't move to the new Subaru Global Platform, upon which the automaker is basing all its new all-wheel-drive vehicles. That leaves two options: staying with the current Subaru platform, or moving to the Toyota New Global Architecture, which underpins vehicles including the Prius, C-HR, Camry and Highlander, and can better accommodate real-wheel-drive layouts. The TNGA would also help save weight and provide economies of scale. "It's a very flexible platform, but we make all-wheel-drive vehicles," the insider told CarSales about the new Subaru platform. "That's our forte, all-wheel drive." The 86 and BRZ launched for 2012, the former as the Scion FR-S, sharing the Impreza platform, Subaru's 205-horsepower 2.0-liter four-cylinder boxer engine and a six-speed manual or automatic transmission. Both brands have confirmed they are working on new vehicles but have declined to offer details, and the source tells CarSales that development at Subaru is well under way. Toyota just revealed its heavily anticipated (and much-dissected) Supra in Detroit in January, based heavily on BMW engineering. The automaker is reportedly keen to build a family of sports cars, with a possible third model under consideration, and is developing the new 86 with plenty of involvement from the Toyota Gazoo Racing division.

Toyota Me.We concept is a multifunction Tupperware car [w/video]

Not to be outdone by the Renault Twin'Z concept penned by Welsh designer Ross Lovegrove, Toyota has partnered up with French designer Jean-Marie Massaud to create the 2013 Toyota Me.We Concept. Unveiled at Le Rendez-vous Toyota in Paris, the Me.We Concept is an attempt to imagine a car that can be appreciated by owners across a wide variety of lifestyles while being courteous to the environment, too.
From a "Me" perspective, the concept is highly customizable with removable body panels, and even though it might look like just a small hatchback from the outside, Toyota claims it can also be used as a pickup (with an extendable rear panel), a convertible (with a neoprene roof panel) and even an off-road vehicle. As for the "We" part of the car, it's a fully electric vehicle with individual in-wheel motors and a battery pack mounted under the load floor. The concept has a weight of around 1,600 pounds kept low thanks to an aluminum chassis, but it also features renewable bamboo wood for the floor in addition to the fully recyclable polypropylene exterior body panels.
