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.

Toyota C-HR Concept is a high-riding hybrid hatch [w/video]

Despite having the tendency to offer decidedly bland production cars, Toyota occasionally surprises us with interesting concept cars. Such is the case with the C-HR concept making its debut at the Paris Motor Show this week. It's a concept showing forward-thinking design that hints at "a type of crossover vehicle Toyota would like to bring to market," according to the automaker's release, and it rides on an all-new platform and uses a hybrid powertrain.
About that powertrain: Toyota isn't revealing anything, just saying that it will - brace yourselves - "deliver significantly improved fuel efficiency" (over what, exactly?) The car also uses a brand-new architecture, though it hasn't really revealed any major details about that aspect, either.
It's a high-riding, muscular thing, with a rakish hatchback shape. Should it reach production, Toyota says it would take the shape of a C-segment crossover. It'd be cool to see something like this hit the road someday, but for now, we won't hold our breath.
