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.

Hyundai, Kia, Genesis and Subaru clean up in IIHS 2018 safety ratings

Hyundai, its partner Kia and its Genesis division are the big winners in the latest vehicle safety ratings from the Insurance Institute for Highway Safety, accounting for six of the 15 models that earned the Top Safety Pick+ awards for 2018. Subaru was right behind with four, Mercedes-Benz had two, and Toyota, BMW and Ford each had one. Another 47 vehicles earned the Top Safety Pick designation, where Toyota had 10 vehicle models, with Hyundai recognized for nine models. All but one of the seven vehicles in Subaru's lineup, the BRZ, qualified for one of the awards. IIHS strengthened the criteria for the Top Safety Pick+ award for 2018 to require headlights to earn a "good" rating — an "acceptable" rating was previously enough to notch the "plus" award — and good or acceptable passenger-side protection in the small overlap front crash, which replicates a crash involving just the front corner of a vehicle. It also required vehicles to have acceptable or good headlights for the first time to earn a Top Safety Pick award. Most of winners for both awards qualified on the basis of optional upgrades. IIHS in October began evaluating the passenger side of vehicles in its small overlap front crash test after it said it became clear that automakers were neglecting that side of the vehicle as they focused on improving driver-side protections. IIHS first began conducting driver-side small overlap crashes in 2012. It began measuring both how well low and high beams illuminated the road and the amount of glare they produce for oncoming vehicles as part of its ratings in 2016. The Top Safety Pick+ winners are listed below. The list doesn't include any minivans, pickups or minicars, which don't appear on either list of awardees.

Toyota builds its 500,000th Corolla in Mississippi

Toyota assembles the Corolla at plants around the world: from Brazil and South Africa to Turkey, Pakistan, China, Taiwan and Thailand. But the one we get here is built in Mississippi, and that location has just finished its 500,000th Corolla. The plant in Blue Springs, MS, is just one of a half-dozen assembly plants Toyota operates in the United States, but reached the half-million mark faster than any of the others. It began production late in 2011 and took over Corolla assembly from the NUMMI plant in California previously operated via joint venture with General Motors and now occupied by Tesla. Last year, the 2,000 workers at Toyota Motor Manufacturing Mississippi built 180,000 Corollas, contributing to the 10 million units of the model Toyota has sold in America since it was introduced here in 1968 and the 21 million vehicles Toyota has made in America over the years. 500,000th Corolla Speeds Off the Line at Toyota Mississippi Blue Springs plant celebrates milestone achieved at record pace BLUE SPRINGS, MISS. (Feb. 12, 2015) – Toyota Mississippi is celebrating the 500,000th Corolla coming off the line at the Blue Springs, Miss., production facility. The production accomplishment was achieved faster than any other Toyota plant in the U.S. – a testament to the 2,000 hardworking team members who have answered increasing consumer demand since the plant opened in 2011. "The 500,000th Corolla vehicle is a milestone we're excited to be celebrating," said Fred Volf, Toyota Mississippi, vice president of manufacturing. "We are proud to produce the Corolla, and it wouldn't have been accomplished without the 2,000 dedicated team members who support this operation." The milestone is one more to add to the long list of achievements for Toyota Mississippi and the Corolla. Toyota has sold more than 10 million Corollas in the U.S. and 40 million worldwide since the vehicle debuted here in 1968. The success of Corolla contributes to Toyota's accomplished domestic manufacturing footprint and represents Toyota's commitment to producing vehicles where they are sold. Since 1986, more than 21 million Toyota vehicles have rolled off the line in the U.S. and including dealers and suppliers, Toyota has generated 365,000 U.S. jobs. Toyota's local presence is felt by those in Northeast Mississippi through substantial economic investment, employment, philanthropic efforts and environmental responsibility.
