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.

Lexus GX, Toyota Land Cruiser Prado facelifts leaked

The Lexus GX and the Toyota Land Cruiser Prado, which isn't sold in the US, have gone without visual updates since the current generation was launched in 2009. But what appear to be patent filing sketches and pictures of the sibling sports utility vehicles' mid-cycle updates have been leaked on a Russian Land Cruiser Club forum.
Major changes to the GX's front end will be made to incorporate Lexus' signature grille. Gone are the awkwardly shaped headlamps and the soft-looking triple-slat grille. The sketch shows the Lexus with a new bumper, lower-profile headlights and a more aggressive, angular grille with one more slat and a gaping lower air-intake opening. The vehicle's profile looks unchanged, but the rear bumper will be reshaped slightly to fit new, better-integrated horizontal reflectors.
The Toyota gets a handful of styling updates as well, including a new front bumper with higher-profile headlamps that look a bit out of place to us. The Prado's profile also looks unchanged, but the rear end gets restyled taillights and a reshaped license-plate enclosure.

Ever wonder how to really pronounce Japanese automaker names?

People tend to get very set in their ways when it comes to the pronunciation of words. Just look at the endless debates over whether or not to say the final 'e' in Porsche (which you should in terms of correct German enunciation). Or the argument about whether to follow the British convention and give the 'u' in Jaguar a special delivery or to say the 'ua' diphthong as more of a 'w' sound, as usually happens in the US.
This short video doesn't answer either of those automotive questions, but it does allow a native Japanese speaker to demonstrate the accepted pronunciations for several, major automakers from the country. One benefit is that it clears up the occasional debate over whether Nissan should be said with a long or short 'i' sound. Also, listen closely to how the female host says Mazda as Matsuda, the way it's actually said in the language. Even if this doesn't change the way you enunciate these brands, at least now you know the accurate way in Japanese.
