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.

2019 Mazda CX-5 to get 2.5-liter turbo and revised G-Vectoring

The 2019 Mazda CX-5 is getting Mazda's 2.5-liter turbocharged four-cylinder engine if this supposed internal document from Reddit is correct. The user claims a salesperson showed him the document in question. In addition to the availability of the turbo engine, Apple CarPlay and Android Auto appear to be added onto every trim level. Do take note that the document says it's from Mazda Canada at the bottom, so that's why the trim levels don't have the same names as they do in the U.S. Another interesting mention in there is G-Vectoring Control Plus. We've had Mazda's G-Vectoring Control technology for a little while, but never has a car come out with the Plus moniker on there. Our best bet is Mazda has revised its original G-Vectoring system for 2019; we'll have to wait for official information to see what exactly changed though. At the top of the page Mazda lists "substantial visual changes to the interior" as one of the highlights. The biggest change we can find related to that is a seven-inch LCD display added to the gauge cluster on what would equate to the Grand Touring trim in the U.S. At least Canada — and maybe we too — seems to be getting a fourth trim level called "Signature." This will probably consist of more expensive materials used throughout and maybe a few bonus tech features over the Grand Touring. The page shared looks plenty legitimate, but it's still best to maintain some healthy skepticism. It's also from Canada, so there could be some slight variations between how those cars are equipped versus those coming stateside. We're excited to see the 2.5-liter turbo in the smaller CX-5, though. It should give that car the extra punch it needs to fend off faster rivals in the ever-expanding crossover segment.

Toddler survives 60-foot fall from apartment window, lands on car

REDMOND, Wash. — A 20-month-old boy survived a six-story fall from suburban Seattle apartment window after the toddler landed on the roof of a parked car that cushioned the impact of the plunge, authorities said. The toddler "landed in a way where the car absorbed enough of the impact that he was awake and crying when paramedics arrived" Wednesday afternoon, Redmond police spokesman James Perry told the KIRO television station. The boy was in serious but stable condition at a hospital. Just before the fall, the toddler was alone in a bedroom, while his mother and two siblings were in another room, Perry said. Investigators believe the boy propped himself on the edge of a window that was cracked open, pushed through a screen and tumbled about 60 feet. The owner of the Mazda sedan that the child fell on was amazed that the boy survived. Edward Lu told KOMO-TV that the only reason the car was there was because he had decided at the last minute to ride his bike to work that day. Had the car been gone, the boy would have landed on pavement. "That's a big dent," Lu said. "I couldn't believe it."
