Toyota recalls 4,000 Tacoma pickups over valve springs

When you build as many cars and trucks as Toyota does, you're bound to run into the occasional recall. In the past month alone, the Japanese auto giant has recalled over 800,000 Camry, Avalon and Venza models over problems with the air-conditioning units, and 10,000 more before that over windshield wiper issues. Now Toyota has issued another recall notice, but this time for far fewer vehicles.
The recall revolves around the engine valve springs in the 2013 and 2014 Tacoma, specifically those fitted with the standard 2.7-liter four-cylinder engine and not the optional 4.0-liter V6. The issue is that the valve springs are prone to cracking and breaking over time, and results from improper maintenance of the manufacturing equipment used by one of the two suppliers that outfit Toyota with the components in question.
All told, some 4,000 vehicles will be subject to the voluntary recall, the owners of which will receive notice by mail. If you think that could be you and want to get a jump on the problem, you can read the announcement below and call Toyota yourself.

Toyota gives up more information on Frankfurt-bound Yaris Hybrid-R concept

Toyota has undeniably carved out a niche for itself as the industry's leader in hybrid propulsion. What started out with the original Prius in 1997 has, over the past sixteen years, ballooned to what Toyota reports as a global hybrid portfolio of 23 models. But few (if any of them) are particularly exciting.
That's where the Yaris Hybrid-R concept comes in. Set to be showcased along with the rest of Toyota's hybrid and fuel-cell lineup at the upcoming Frankfurt Motor Show next month, the concept starts with one of the Japanese auto giant's least exciting models and upgrades it to more enticing territory. Toyota Motorsport GmbH - the same Cologne, Germany-based division that operated the company's F1 team, currently runs its Le Mans program and gave us that bonkers 650-horsepower Lexus LS - has slotted in a version of Toyota's new 1.6-liter Global Race Engine and paired it with a couple of electric motors for hybrid propulsion and through-the-road all-wheel drive.
Like the TS030 Hybrid LMP1, the Yaris Hybrid-R concept uses a super capacitor (instead of a conventional battery) to store the regenerated brake energy and give it upwards of 400 horsepower. That's about all Toyota is revealing at this point, but this is the first time it has confirmed the project is based on a Yaris, of all things, and the confirmation comes with the solitary teaser rendering you see above. Check out the press release after the jump and watch this space for more as Frankfurt fast approaches.

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.
