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.

Has the auto industry hit peak hybrid?

Hybrids are known for their great fuel economy and low emissions, but it looks like given current market conditions, only about three percent of new car consumers are willing to pay the premium for them. A new study from IHS/Polk finds that the hybrid market share among overall US auto sales are falling, despite more models with the technology on sale than ever before.
The study examined new car registrations in March from 2009 through 2014. In that time, the auto industry grew from 24 to 47 hybrid models available to consumers, but market share for the powertrain remained almost stagnant in that time. As of 2009, hybrids held 2.4 percent of the market; it fell slightly to 2.3 percent in 2010 and grew to 3.3 percent in 2013. However, 2014 showed a drop back to 3 percent. Overall hybrid sales have been growing since 2010, but they just aren't keeping up with the total auto market.
According to IHS/Polk, this isn't what you would expect to see. Usually, each new model in the market brings along with it a boost in sales. The growth in hybrid models 2009 to 2014 should have shown a larger increase in share for the segment.

2015 Toyota Prius Persona special edition arrives in September

Is the Prius going into "Pimp My Ride" territory? A new official special edition model won't be lowered or have three-wheel motion or anything like that (though that'd be cool), but the world's best-selling hybrid is putting on a few stylish bells and whistles this September. Toyota has announced something called the 2015 Prius Persona Series Special Edition. Included on the special variant will be 17-inch alloy wheels, a metallic exterior finish, heated power mirrors and chrome shift knob rings and door grips. Inside, you've got special badging and black SofTex fabric stitched with gray. The new Prius Persona will come in two colors: "Blizzard Pearl" and "Absolutely Red." The special edition has base price of $26,985, and the "Blizzard Pearl" option knocks it closer to the $27,400 mark and there's also the $895 (give or take) delivery fee. Demand for the Prius in the US has plateaued recently as other automakers have broadened their selection of advanced-powertrain vehicles. Through the first half of the year, combined sales of the four Prius variants were down 11 percent from 2013 numbers to about 107,000 units, including about 63,000 of the standard sedans and almost 20,300 of the Prius C compact hybrids. Perhaps there are enough personas out there that sales will get a boost from this special edition. Take a look at Toyota's press release on the 2015 Prius Persona below. SPECIAL EDITION PRIUS TAKES ON A NEW PERSONA FOR 2015 TORRANCE, Calif. (July 30, 2014) – The best-selling hybrid in America is taking style to a new level.

The Prius Persona Series Special Edition model adds exterior changes and equipment to a Prius Three to create a distinct visual package. Persona Series includes 17-inch alloy wheels with a premium dark metallic finish. The special edition also comes equipped with premium heated power mirrors with turn signal indicators. The Persona model will be available in two exterior colors, Blizzard Pearl, and for the first time ever on this model, Absolutely Red.
