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.

Eiji Toyoda dead at 100

Toyota has had number of chiefs over its 76-year history, but none ever served as long as Eiji Toyoda. The younger cousin of the company's founder served as president of the automaker from 1967 to 1982 and as chairman of the Toyota Motor Corporation for another ten years following the unification of the manufacturing and sales divisions.
During his 25 years at the helm, Eiji Toyoda (pictured above in 1967) was credited with establishing the company's headquarters in Toyota City, spearheading the development of the Prius, expanding production overseas for the first time, launching the Lexus brand and turning Toyota from a minor player into one of the largest automakers in the world.
Even after his retirement in 1992, he remained an honorary chairman and close advisor to his successors, and chaired the company's museum. He died of heart failure, ending a 100-year life that started on September 12, 1913, before the company that bore his family's name (albeit slightly modified) had even started building automatic looms, let alone automobiles. We extend our condolences to the Toyoda family and our congratulations on an accomplished life.

Toyota JV will sell Leahead EVs in China next year

You may have read that Toyota is about to establish a new electric vehicle sub-brand in China called Leahead that will focus on "cheap electric cars aimed at young and hip car buyers in China." This isn't 100 percent true, but the Japanese automaker is revving its electric motors for EVs in China, in a fashion. It makes sense for automakers to push for more EVs in China, given government support for the technology and the proven success of Tesla there. Low-speed EVs are popular, as well. Indirectly, Toyota is going to sell electric vehicles to Chinese customers next year. We've heard reports before that Toyota is interested in going electric in China, with a different Toyota JV and thus a different brand but now we have an official word on Toyota's future EV moves in China, direct from Jana Hartline, the environmental communications manager for Toyota Motor Sales, USA. Hartline told AutoblogGreen that Toyota just celebrated the 10-year anniversary of GAC Toyota Motor Co., Ltd (GTMC), its joint-venture manufacturing company in China. And it is GTMC, not Toyota directly, that is the company behind Leahead (called Ling Zhi in Chinese). Leahead will begin selling EVs under the Ling Zhi brand starting in 2015. So, yes, indirectly, Toyota is going to sell electric vehicles to Chinese customers next year. There are rumors that the new EVs will be electric versions of the Corolla EX and/or the Yaris L, but we've got nothing confirmed on that front. We will be waiting for more new at the Shanghai Motor Show next April.
