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.

BMW i5 returns as next rumored i Project vehicle

Hydrogen fuel-cell vehicle enthusiasts may want to give each other some high-fives when they hear the latest news about BMW's reputed i5. The German automaker has been rumored to be on the verge of expanding its i brand beyond its i3 battery-electric and i8 plug-in hybrid cars for a long while. The latest rumors say that BMW could be working on a hydrogen-powered i5 crossover. BMW is in the "final stages of consideration" of expanding the sub-brand, Bloomberg News says, citing comments BMW executive Ian Robertson made this week at the Frankfurt Motor Show. There may be more light-weighting efforts, and an alternative powertrain is sure to be in order, but there are few details beyond that. BMW of North America spokeswoman Rebecca Kiehne declined to comment to AutoblogGreen. Since 2013, BMW has worked with Toyota on hydrogen fuel-cell drivetrains and might further expand that relationship, MarketWatch says, citing BMW financial chief Friedrich Eichiner. The two automakers have already worked together on a prototype BMW 5 Series sedan with a hydrogen-powered engine. That car was unveiled this summer. Earlier this year, we heard reports about an i5 that would actually be a hybrid-electric vehicle of sorts, and an extremely powerful one. That rumored vehicle – again some sort of modified 5 Series – would actually contain one gas-powered engine and two electric motors, all combining for more than 540 horsepower. If these latest rumors turn out to be true, they would mark a change in things, but we won't be surprise if we hear yet another version of what the i5 will be before it's all said and done.

Tougher than steel: Wood pulp could make lighter auto parts

KYOTO, Japan — The global push among carmakers to make ever lighter vehicles is leading some auto suppliers in Japan to turn to what seems like an unlikely steel substitute — wood pulp. Japanese researchers and auto component makers say a material made from wood pulp weighs just one-fifth of steel and can be five times stronger. The material - cellulose nanofibers — could become a viable alternative to steel in the decades ahead, they say, although it faces competition from carbon-based materials, and remains a long way from being commercially viable.> Related: Jay Leno drives the Renew cannabis car — hemp you can't dent Reducing the weight of a vehicle will be critical as manufacturers move to bring electric cars into the mainstream. Batteries are an expensive but vital component, so a reduction in car weight will mean fewer batteries will be needed to power the vehicle, saving on costs. "Lightweighting is a constant issue for us," said Masanori Matsushiro, a project manager overseeing body design at Toyota. "But we also have to resolve the issue of high manufacturing costs before we see an increased use of new, lighter-weight materials in mass-volume cars."A NEW PROCESS Researchers at Kyoto University and major parts suppliers such as Denso Corp, Toyota's biggest supplier, and DaikyoNishikawa Corp, are working with plastics incorporated with cellulose nanofibers — made by breaking down wood pulp fibers into several hundredths of a micron (one thousandth of a millimeter). Cellulose nanofibers have been used in a variety of products ranging from ink to transparent displays, but their potential use in cars has been enabled by the "Kyoto Process," under which chemically treated wood fibers are kneaded into plastics while simultaneously being broken down into nanofibers, slashing the cost of production to roughly one-fifth that of other processes. "This is the lowest-cost, highest-performance application for cellulose nanofibers, and that's why we're focusing on its use in auto and aircraft parts," Kyoto University Professor Hiroaki Yano, who is leading the research, told Reuters in an interview. The university, along with auto parts suppliers, are currently developing a prototype car using cellulose nanofiber-based parts to be completed in 2020.
