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 gives dealers permission to drop Scion, shows them FR-S droptop, Juke rival first

We recently heard that Toyota could be looking to shrink its network of Scion dealerships, and now Automotive News is reporting that the automaker has officially given its dealers the green light to dump Scion without any penalties. Currently, Scion has about 1,000 dealers, yet our report from August 8 quotes an industry analyst as suggesting a healthier figure would be between 350 and 500 outlets. But before its current dealers make a decision on whether or not to get rid of the youth-oriented brand, Toyota also showed off a couple potential future products in the pipeline.
The FT-86 Open Concept shown above was revealed back in March at the Geneva Motor Show, and AN says that an FR-S convertible was driven on stage at a recent national Toyota dealer meeting in Atlanta. There has still been no definitive word one way or another as to whether the droptop model will be built, but it could be a good way to follow up to the popular FR-S coupe. Another possible future product is a subcompact crossover, which was shown in drawing form at the meeting, presumably aimed at small CUVs like the Nissan Juke and the upcoming Honda CUV based on the Fit, a model recently previewed by the automaker's Urban SUV concept.

Toyota settles for $3M after being found liable in sudden acceleration case

A jury has decided that faulty software was to blame for a crash involving a 2005 Toyota Camry that killed one woman and injured another. This is the first time Toyota has been found liable by a jury in a lawsuit involving sudden acceleration claims. Toyota has maintained that driver error is the most likely cause for cases of sudden acceleration.
Shortly after the jury in the case, which took place in Oklahoma and centered around a crash that injured 76-year-old Jean Bookout and killed her passenger, Barbara Schwarz, reached a verdict that would see Toyota paying $3 million in compensatory damages, a confidential settlement was reached. The jury, which had found Toyota liable for "reckless disregard" for public safety, had yet to decide what punitive damages Toyota would face.
Toyota said in a statement, "While we strongly disagree with the verdict, we are satisfied that the parties reached a mutually acceptable agreement to settle this case. We will continue to defend our products vigorously at trial in other legal venues."
