Toyota may put Mirai hydrogen fuel cell powertrain into a Lexus

Toyota is hoping to define the world of hydrogen fuel cell vehicles with its uniquely styled Mirai sedan in a fashion similar to the way the Prius pops into people's minds when they think of a hybrid. The Japanese automaker believes it can sell about 700 FCEVs worldwide in the first year alone and build rapidly from there to an estimated 3,000 sales in the US by 2017. Of course, not everyone is completely enamored with the Mirai's design. Toyota is rumored to have an alternative in the works to quell some of those naysayers, possibly taking flagship form with a new Lexus LS powered by fuel-cell tech. The LS FCEV could be unveiled by 2017 to sit at the very top of brand's lineup. According to an inside source speaking to the Australian website Motoring, the front end would feature larger air intakes to cool the electrical components. The fuel cell would reportedly be positioned under the front seat, and the hydrogen tanks would be located under and behind the rear seat. Somehow, Motoring claims that all of this might be lighter than the current LS600hL hybrid, to the tune about 440 pounds. The model is also claimed to offer a range of about 239 miles, just a bit shy of the Mirai's roughly 300 miles. Assuming this vehicle actually exists, the cost for buyers of this flagship would almost certainly ring up at more than the LS600hL's $120,440 base price. Autoblog has reached out to Toyota for any further info about this rumor, one way or the other. If we hear back, we'll update this story with the details.

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.

Scion reveals iM concept ahead of LA debut

After dropping a teaser image on us a few weeks ago, Scion has revealed in full the new iM Concept it's bringing to the Los Angeles Auto Show next week. As expected, the concept is clearly a rebadged version of the Euro-market Toyota Auris, only with some "European Racing Circuit Styling" upgrades to make it look more aggressive.
Along with the Scion logos, the five-door hatch is treated to a deeper air dam flanked by angular vents with stacked fog lamps, beefed-up wheel arches linked by widened side sills and filled with 19-inch, anthracite-finish alloys on low-profile rubber. Vented brake discs and four-piston calipers join an adjustable suspension as show-worthy equipment upgrades.
The sporty treatment continues around back with a similarly aggressive rear bumper and roof spoiler. Even the wing mirrors are replaced with narrower units. Little wonder it's all done up in a shade Scion calls "incrediblue" that looks rather similar to what sister-brand Lexus would put on one of its F-branded performance models - or for that matter what corporate ally Subaru would put on an STI hot hatches like the WRX.
