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 Camry to go turbo

As automakers strive to meet regulations, turbocharging is rapidly becoming the norm whether looking at pickups, sports cars or family sedans. However, Toyota remains a stalwart to the changing tide, and for the time being a trip into one of the brand's dealers shows nary a hint of forced induction – probably not for long, though. With models like the Lexus NX 200t and forthcoming IS 200t pointing the way, a big shift is afoot for one of the Japanese automaker's most popular products. Obviously, Toyota is no stranger to forced induction for performance applications like the turbocharged models of the Supra and MR2 in the '90s. But rather than reducing lap times, the latest application is more about improving emissions and fuel economy. According to Automotive News, the Camry is getting a 2.0-liter turbo four-cylinder in the near future as a replacement for its V6 engine option. The 3.5-liter six currently in the venerable sedan already makes 268 horsepower and 248 pound-feet of torque, versus 235 hp and 258 lb-ft in the NX 200t or 241 hp and 258 lb-ft in the IS from the new four. The base four-cylinder also might receive some upgrades. It could grow larger and run on the Atkinson cycle to find improvements, according to Automotive News. There might be a move towards CVTs, as well. Toyota is hardly alone in the shift towards forced induction. Honda is known to have a 1.5-liter turbo mill on the way for the next-gen Civic. In addition, that engine might find its way into the Accord and CR-V as well, according to Automotive News. Among the major Japanese automakers, only Nissan is taking a more measured approach towards forced induction in mainstream models. Rather than going all-in on turbos, the company is expected to shift more of its engines to direct injection to go after fuel economy gains.

Translogic 164: Driving the fuel cell vehicles of the 2014 LA Auto Show

The LA Auto Show is known for its environmentally friendly vehicle debuts. At last year's show, hydrogen fuel cell concepts from Honda and Toyota joined a lease-ready Hyundai Tucson FCEV to cast a green hue over the convention center. This year, automakers took us a step closer to a fuel cell future by offering drives of their hydrogen-electric hybrids. Translogic host Jonathon Buckley takes a ride in the Toyota Mirai, which is headed for production in 2016. He follows that with a spin in the Volkswagen Passat HyMotion and the Audi A7 Sportback h-tron quattro concept. Which of these fuel cell vehicles holds the most promise? Tune in to find out.
