New Toyota Mirai videos continue questionable hydrogen claims

"Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint." Toyota has released a number of new promotional videos for the hydrogen-powered 2016 Mirai. Most are exactly what you'd expect: pretty, full of promise and vaguely informational. But there was one line in the Product Introduction video that caught out ear. In the Product Information video about the Mirai, the narrator goes into a short history of Toyota's green car advances. After talking about the Prius and the Prius Plug In, making EVs for urban commuting and the rest of Toyota's advanced fuel programs, we hear this: "Never satisfied though, Toyota engineers were simultaneously working on a brand new technology that met all the driver's needs with an even smaller carbon footprint, one that took its lead from nature itself." You can watch the video (and four others) below. Plug In America co-founder Paul Scott told AutoblogGreen, "Show us the math! Toyota claims the FCV has a smaller carbon footprint than their EV, but every paper I've read indicates the FCV uses 3-4 times as much energy to travel a given distance as an EV. If they are making this claim, let's call them out to prove it. Show us the math!" There's some math that comes out in favor of EVs here and here. "BEVs and FCs have a very similar carbon footprint, dependent on fuel source." – Toyota's Jana Hartline Plug-in vehicle advocate Chelsea Sexton went further. "Assuming appropriate comparisons in energy feedstock, basic science doesn't support the notion that the footprint of an FCV is smaller than that of an EV," she told AutoblogGreen, explaining that "appropriate comparison" would mean using similar energy generation methods for both hydrogen and plug-in vehicles. Not the tendency, she noted, "of H2 fans to compare FCVs based on solar-based electrolysis to EVs running on coal-bases electricity and similar shenanigans." Besides, Sexton said, "focusing purely on efficiencies entirely misses the biggest struggles that FCVs face in the market, namely fuel price, inconvenience, and market fear, even if the vehicles themselves are initially subsidized.

Toyota's new TNGA platform could boost Prius to 58 mpg

First, let's put the necessary context around the phrase, "Toyota New Global Architecture platform." The platform is important, but it is just one flowering bud sprouting from the real action, which is the production processes that will create it. It is crucial to understand that TNGA is fundamentally about a revolution in how Toyota designs and builds its cars - it even includes an overhaul of management and human resources - with one of the benefits being the new platform that the 2016 Prius will ride on. The Daily Kanban goes in depth about the changes, but integrated development for powertrain and platforms serves to reduces costs through more parts-sharing at the same time as it creates more cohesive platforms that are lighter, more compact, and have more efficient layouts. Regarding hybrids, Toyota says the new drive unit layout along with small components could raise hybrid efficiency "by more than 15 percent." That might enable the 2016 Prius to return 57.5-mpg combined - almost 59 in the city, 55 on the highway. Plus, the higher rigidity, lower center of gravity, and better suspension of the new platform will provide a better driving experience. All of these changes will be reflected in platforms for large and rear-wheel-drive vehicles, too. It is factory and build-process refinement that allows the development advances to be fully exploited. Toyota is making its lines more flexible, partly by having actual assembly lines that can easily be shortened, lengthened, or trucked somewhere else, and partly by introducing machines that can build parts for many different vehicles on the same line as needed, without using molds. The flexibility extends to capital investment, too, with much less money needed in order to switch to a new product build. Toyota says it is doing this to "improve core vehicle performance and product appeal," the overhaul making it simpler to produce new designs and features. Factory workers benefit from the flexibility as well; being able to build more types of cars means they aren't hamstrung by the sales fortunes of a small number of models. You'll find plenty of specifics in the press release below.

10 automakers shack up in Detroit hotel to talk Takata airbags

Since Takata has decided not to take the lead concerning potential issues with its airbag inflators, the automakers have. Perhaps that's unsurprising, since it's the automakers, not Takata, that will take a beating on the dealership floor if consumers decide its models are a health hazards. The Detroit News reports that Toyota, Honda, General Motors, Ford, Chrysler, Mazda, BMW, Nissan, Mitsubishi and Subaru met in a hotel conference room near the Detroit Metropolitan Airport last week to sort out a way to understand the technical issues involved. So far, faulty airbag inflators have been ruled the cause of five deaths and 50 injuries around the world, but neither Takata nor investigators understands exactly why the inflators are malfunctioning. The National Highway Traffic Safety Administration recently asked Takata to issue a national recall, Takata declined, citing a minuscule failure rate and the fact that it's still investigating the issue. Toyota and Honda then made an industry-wide appeal for "a coordinated, comprehensive testing program" that would pinpoint the problem inflators and get them replaced, and that's what the Detroit meeting was about. Numerous issues, however, will make this a long row to hoe: simply getting the parts to replace the nearly 20 million inflators in cars recalled around the world so far - even working with other suppliers - will take a years, but more importantly, no one knows if the replacement inflators currently being installed will suffer the same issue. Answers will hopefully come quickly with Takata, the ten automakers and NHTSA all independently investigating the problem.
