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.

Owner reflects on his $20.91 Toyota unintended acceleration settlement check

Where General Motors and Takata have grabbed many auto safety-related headlines this year with their problems with ignition switches and airbag inflators, a few years ago, a similar sort of scrutiny fell on Toyota for unintended acceleration. After multiple settlements with various parties totaling billions of dollars, the issues seem largely behind the Japanese automaker now. Owners are actually starting to receive their money, but it isn't exactly breaking the bank. Payouts are expected to be between $37 and $125 per person. Computer science student Jonathan Sourbeer received a check for just $20.91, and he considers what that money actually means in an op-ed in The Wall Street Journal. Sourbeer's biggest gripe is that the roughly 85 lawyers in the case are receiving $227 million in attorneys' fees and expenses, while the 25 primary plaintiffs and class representatives receive a total of just $395,270. According to the Frequently Asked Questions about the settlement, Toyota set up a $250 million fund to pay affected owners, as well. The money isn't for injuries or damages but for alleged economic loss to the vehicles. However, Sourbeer says he feels no personal suffering and still has the same car. In addition to the settlement, the automaker obviously has its own legal fees to deal with, as well. Sourbeer wonders how this is all going to affect Toyotas in the future. Obviously, the money has to come from somewhere, and it likely gets amortized over the company's vehicles in the coming years to add a few dollars to each one. That puts the problem back onto customers. Anyone involved in a class-action suit has likely seen this happen first hand. The lawyers take a large chunk of the money, and the rest is distributed in tiny morsels to those actually affected. Unfortunately, Sourbeer offers no solutions beyond saying the system needs to change.

PickupTrucks.com's latest test results in a familiar winner [w/video]

PickupTrucks.com has gone and thrown the latest batch of half-ton pickups into a cage match to see who would come out on top. The site put the 2014 Chevrolet Silverado 1500, GMC Sierra 1500, 2013 Ford F-150, Ram 1500, Toyota Tundra and Nissan Titan through a battery of tests. Those included 0-60 miles per hour acceleration, 60-0 mph deceleration, fuel economy, a hill climb, and payload and towing. They even threw the rigs on an autocross course to evaluate overall handling. Each truck was given points based on how it scored in each evaluation.
Who came out on top? Somewhat surprisingly, the 2013 Ford F-150 walked away with the gold, though fewer than 50 points separated first and fourth place. Head over to PickupTrucks.com to read the full evaluation and the final results. You may be shocked to see exactly where some of the segment's newest additions placed. You can also watch a video on the test below.
