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.

2014 Toyota Prius crash test rating drops to four stars

If nothing has changed, then how come something changed? That's the question behind the recent drop from five to four stars in the crash test rating for the Toyota Prius. As you can see on the National Highway Traffic Safety Administration (NHTSA) website, the 2014 Prius gets four stars overall while the 2013 got five. The two cars are basically identical, so what gives? Toyota says it is not sure why NHTSA rated the Prius a four this time. Starting with the 2011 model year, NHTSA updated its rating system and says in a FAQ that vehicles that had four- or five-star ratings could get lower ratings "even if no changes have been made to the vehicle." Green Car Reports says that the issue is a new set of frontal barrier tests that were conducted on the 2014 Prius last month and that resulted in the first new bits of crash test data for the car in years. The 2012 and 2013 Prius models were rated based on tests done in February 2011 on a 2011 Prius. All of these are variants of the third-generation model. The next-gen Prius is expected in 2015. Jana Hartline, environmental communication manager at Toyota Motor Sales, USA, told AutoblogGreen that the company doesn't quite know what's going on with the drop in crash test scores: There have been no changes in the test standards and no changes in the car, other than minor reinforcement for small overlap crash test which we believe did not compromise integrity. We are not sure why it rated a 4 this time. We are looking at the test results and we are confident the new generation will move back to 5 stars. 2014 Prius still has a five-star rating for the side crash test and four in the rollover test.

Two new RWD Toyota sports cars to join FR-S?

Toyota as we know it could become a thing of the past. According to Australian site Car Advice, the Japanese brand known for bland cruisers like the Camry and Corolla is preparing to bring two new rear-drive cars to market that would slot above and below the Scion-badged FR-S. This is very, very good news.
Car Advice spoke to the GT86/FR-S' chief engineer, Tatsuya Tada, who claimed, "Akio Toyoda always says to me, Toyota sports car [family] should be three sports car brothers. 86 is in the middle." The oldest "brother" would be the spiritual successor to the Supra, even if it doesn't wear that name. Tada is in charge of that project, while a sub-GT86 project is being headed-up elsewhere.
Tada refused to comment on names (CA specifically mentions MR2 and Celica) for the new small car, but did say that, "Yes it is rear-wheel drive and that's Toyota's strong position - Toyota sports car must be rear-wheel drive." Perhaps the juiciest bit of information obtained from Tada's interview with Car Advice was his hinting that both new sports cars would be joint ventures, like the GT86/FR-S/Subaru BRZ triplets. Tada wouldn't say who Toyota was in bed with on the smaller model, but did mention that the Supra would be a product of the world's largest automaker's partnership with BMW.
