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.

Toyota promises a next-generation Land Cruiser is on its way

On sale since the 2008 model year and facelifted twice in the interim, the Toyota Land Cruiser has lately begun rolling out the special editions. Last year we got the 2019 Lexus LX Inspiration, this year we got the 2020 Land Cruiser Heritage Edition. This likely means a changing of the model guard is close, the 300-Series Land Cruiser on the horizon to replace the current 200-Series. When Motor Authority asked Toyota SVP Bill Fay about the U.S. getting the next generation, Fay replied, "We are fully committed to the Land Cruiser for the foreseeable future." The reason for the question could have been Land Cruiser sales figures for the past 14 years, when the model never cleared 5,000 units. The swankier Lexus LX sibling sells in greater numbers, but even lumping the two trucks, they've crested 10,000 sales just twice since 2005. On top of that, two of the largest regional markets for the Land Cruiser are Australia and the Middle East, which have different regulatory regimes, and the 2019 Highlander has a three-row option. Why carry on with the Land Cruiser here? Fay told MA the body-on-frame bruiser is a "heritage vehicle," a staple in the U.S. lineup since 1958. But the Cruiser that comes next is expected to LS-ify its powertrain formula, which means getting rid of V8s for V6s. The 5.7-liter V8 with 381 horsepower, 401 pound-feet of torque, and an EPA rating of 15 miles per gallon combined should go away. The 3.5-liter twin-turbo V6 in the Lexus LS 500 gets the nod to take its place, as the Land Cruiser make concessions to fuel economy and emissions standards. A poster on a forum said it's possible that a Dynamic Force version of that engine might appear. As is, that engine makes 416 hp and 442 lb-ft in the luxury sedan and is mated to a 10-speed automatic, the same transmission said to replace the current eight-speed in the Land Cruiser. Automotive mediums predict a hybrid Cruiser, too, potentially with the same 3.5-liter naturally aspirated V6 and 10-speed auto in the LS hybrid, putting out 354 combined horsepower in the sedan. Because there are so many Land Cruiser versions around the world, it's impossible to say whether V8 options will die globally. Land Cruiser fans, either through desperation or good intel, say that isn't the case.

2.1 million vehicles recalled again over faulty airbags

Fiat Chrysler Automobiles, Honda and Toyota will recall 2.1 million vehicles to fix faulty airbag modules "after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles." These vehicles had all previously been recalled, but the National Highway Traffic Safety Administration found that the airbags could still potentially malfunction. This recall will cover Acura MDX, Dodge Viper, Jeep Grand Cherokee, Honda Odyssey, Pontiac Vibe, Toyota Corolla, Toyota Matrix and Toyota Avalon models made in the early 2000s. NHTSA has reportedly received about 40 reports of airbag deployment in such vehicles, even though the vehicle had not been involved in a crash. Roughly one million of these same vehicles, all from Honda and Toyota, are also subject to recalls due to faulty Takata airbag modules, though this particular recall is for "an electronic component manufactured by TRW" that is separate from the actual airbags from Takata. According to NHTSA Administrator Mark Rosekind: "This is unfortunately a complicated issue for consumers, who may have to return to their dealer more than once. But this is an urgent safety issue, and all consumers with vehicles covered by the previous recalls should have that remedy installed. Even though it's a temporary solution until the new remedy is available, they and their families will be safer if they take the time to learn if their vehicle is covered and follow their manufacturers' instructions. A hassle is much better than a family tragedy." If you're the owner of an affected car, expect to hear more from the official automaker and government channels in short order. In the meantime, we'd suggest getting your car checked and fixed at your local dealer. The official statement and recall information can be found below. Previously Recalled Vehicle Remedies Not Working as Designed; NHTSA Announces Follow up Recall of 2.12 Million Cars and SUVs Saturday, January 31, 2015 Contact: Gordon Trowbridge, 202-366-9550, Public.Affairs@dot.gov WASHINGTON – U.S. Transportation Secretary Anthony Foxx announced today the recall of more than 2.12 million Acura, Dodge, Jeep, Honda, Pontiac, and Toyota vehicles for a defect that may cause airbags to deploy inadvertently. The recalls will provide vehicle owners with a new remedy after the manufacturers' original attempts to fix the defects proved ineffective in some vehicles.
