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.

The 300-series Lexus LX will have V8, greater differentiation from Land Cruiser

For the first time in 64 years, there will not be a Toyota Land Cruiser sold in the U.S. The venerable off-roader is not in Toyota's 2021 American lineup, but the rest of the world will still get the next-generation Cruiser, called the 300 series internally, later this year. However, we may still receive a version of it badged as the Lexus LX. Here's what a new report suggests we might see. According to the Japan's Best Car magazine, the next LX will be more differentiated from its Land Cruiser cousin. The exterior is reportedly more distinctive, and the interior designed to be more suitable for a flagship luxury SUV. It'll still wear a version of the Lexus spindle grille, with different hood, fenders and quarter panels than the Cruiser. Naturally, the head- and taillights will differ as well. Most importantly, the LX will continue to use a ladder frame. Best Car says that the LX will continue to offer a 5.7-liter V8 good for 372 horsepower (which in the U.S. gives 383 horsepower). However, the Land Cruiser will ditch the V8 for a 3.5-liter turbo V6, offered with and without a hybrid system. Notably, the hybrid will not be the same as the one found in other Toyota cars, but a combination 10-speed automatic and motor that's more suitable for a heavy vehicle.  Last but not least, the report states that Toyota will also create a GR Sport version of Land Cruiser. Presumably, that means some dressier aero bits, larger wheels, and a suspension more tuned for highway, um, cruising.  The Land Cruiser is scheduled to debut in September 2021, while the Lexus may follow a couple of years later, despite being developed in parallel. The LX is considered to be more of a Lexus flagship than the LS sedan in many parts of the world, so it makes sense that Toyota will continue offering it. Related Video:
