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.

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.

Toyota bringing updated Avensis to Geneva

The upper end of Toyota's sedan lineup in America may be all about the Camry and Avalon, but that's not the case everywhere in the world. Back home in Japan, Toyota offers the Crown and the Mark X. But in Europe, it all comes down to the Avensis. And the Japanese automaker is about to roll out an updated version at the upcoming Geneva Motor Show. The Avensis, for those unfamiliar, is Toyota's challenger to the likes of the Ford Mondeo (which we know as the Fusion) and the Volkswagen Passat, available in both sedan and wagon forms. It was first introduced in 1997 and is currently in its third iteration, but what you see here is not the fourth-generation model but an update on the MkIII that hit the European market in 2009. Full details on the refreshed model have yet to be disclosed, but the new Avensis clearly benefits from revised styling – carried out at the company's design studio in the South of France, with production to continue at the Burnaston plant in the UK. Expect a revised interior, updated equipment and a new engine range to also be part of the mix when the new Avensis is revealed in full early next month in Switzerland. TOYOTA TO REVEAL NEW AVENSIS AT THE GENEVA MOTOR SHOW Toyota will reveal the new Avensis at the Geneva motor show (3 – 15 March), the latest development of its contender in the European mid-size (D-segment) car market. New Avensis has been styled at Toyota's ED2 design studio in the South of France and developed by the company's R&D centre in Brussels. It will be built by Toyota Manufacturing UK at the Burnaston car plant, near Derby. The new model will deliver innovations in comfort and safety and will feature a new range of engines that promise both performance and efficiency. Avensis has been designed to appeal to fleet and private customers alike. Toyota will present new Avensis and host a press conference on its stand at the Geneva motor show at 12:15 on 3 March.
