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.

Half of Chinese car buyers won't shop Japanese over hard feelings

The hard feelings between China and Japan is no real secret. Besides modern-day disputes, the two countries have had a long-running enmity that dates back to well before the atrocities of World War II. All things considered, then, it shouldn't be a shock that half of Chinese car buyers wouldn't consider a Japanese car. This survey, conducted by Bernstein Research, found that 51 percent of 40,000 Chinese consumers wouldn't even consider a Japanese car – which, again, isn't really surprising, when you consider stories like this. According to Bernstein, the most troubling thing is the location of these sentiments – smaller, growing cities where the population is going to need sets of wheels. We imagine it wouldn't be as big of an issue in traffic-clogged Shanghai or Beijing, but these small cities are going to become a major focus for automakers. "Nationalistic feelings are an impediment. [Japanese] premium brands will struggle," analyst Max Warburton wrote in a research note, according to The Wall Street Journal. Things will improve for Japanese makes, although China will remain a challenge, with Warburton writing, "the one thing that comes out most clearly is that most Chinese really want a German car. While we expect Japanese brands to continue to recover market share this year, ultimately the market will belong to the Germans." There are a few other insights from the study. According to WSJ, Japanese brands are viewed better than Korean brands, and they're seen as more comfortable than the offerings from Germany or the US, despite the fact that everyone in China apparently wants a German car. This is a tough position for the Japanese makes to be in, as there's really not a lot they can do to win favor with Chinese buyers. It will be interesting to see how this plays out, particularly as the importance of the PRC continues to increase year after year.

Fourth-gen Mazda MX-5 Miata could get turbo power later in life

While there's a lot to love about the new Mazda MX-5 Miata, its debut was met by a vocal group of enthusiasts who derided the fourth-generation roadster's reduction in power output. The new model only puts out 155 horsepower, down from 167 in the NC. A report from Australia, though, claims Mazda may yet address the less potent output of the ND. Things started earlier this year, as Motoring.com.au tells it, when Mazda's global PR boss, Kudo Hidetoshi, hinted that a turbocharged or Mazdaspeed model "will definitely" be considered. Then last month at Goodwood, the ND's program manager, Nobuhiro Yamamoto, said complainers were welcome to get their thrills elsewhere. Recognizing this contradiction among Mazda's brass, Motoring asked Yamamoto-san again about his statements, which he seemed to walk back. "It's not a conflict [between statements made by Yamamoto and Hidetoshi]," Yamamoto said, indicating that his statements were made in relation to the new MX-5's launch. "Kudo-san talked about this in terms of a 10-year lifespan, but when I was asked the question right after the launching of the ND, I said 'we have no plan to have a turbo at that point in time.' That is what I meant." Seeking an opening, Motoring pushed the Japanese engineer on the chances of a more potent MX-5, perhaps without a turbocharger. "If you could achieve what we want, to which is great response, very light and powerful with great performance feel with natural aspiration, then we don't need a turbo," Yamamoto said. "But if we want more power because we don't get satisfied with natural aspiration then we may think about the turbo." Related Video:
