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 takes aim at Musk's criticism of hydrogen 'fool cells'

Tesla's Elon Musk has called hydrogen fuel cell cars "a load of rubbish" and "fool cells," and he's nowhere near alone in his disdain for the technology. Toyota has been fighting back waves of condescension for years now, and did so again when Senior VP Bob Carter took the stage at the recent J.D. Power Automotive Summit this month. His target was comments that Musk made at the Automotive News World Congress at the Detroit Auto Show, when Musk said an FCEV was an "extremely silly way" to store energy, that "the best-case hydrogen fuel cell doesn't win against the current-case battery" and that hydrogen's failings will become obvious in the next few years. Carter's response was that the fuel cell initiative isn't about the next few years. "This is not a 24-to-36-month play, but when you start looking into the 2020s," then you can see the necessity of hydrogen fuel cells, which Toyota considers an extension of EV technology, he said. The Toyota Mirai will begin its defense of the FCEV industry in the US later this year. The Hyundai Tucson Fuel Cell is already available in California and Honda's hydrogen car will arrive in 2016. Until then, we can let some more of Carter's words ring in our ears: "If I was in a position where I had all my eggs in one basket," he said of Musk's BEV-only focus, "I would perhaps be making those same comments."

Honda Civic overtakes Toyota Corolla as America's best-selling compact

The battle to claim October's best-selling compact sedan title has been won by the Honda Civic. The Japanese four-door sold 27,328 units, leaving the Toyota Corolla - September's title holder - in its wake with 23,637 units sold. In terms of year-to-date sales, the Civic sits at 280,899 units, with the Corolla trailing at 257,184 vehicles.
Sitting in third place, separated by a significant gap from the leaders, is the Chevrolet Cruze with 16,087 units sold. The Ford Focus earned fourth, with 15,108 units moved out of showrooms. (It is interesting to note that while the Civic and Corolla have both enjoyed double-digit sales increases year-over-year, the Cruze and Focus have seen significant decreases during the same period.)
Sales of the Hyundai Elantra hit 14,876 units, putting it in fifth place, with the Volkswagen Jetta earning sixth place with 11,710 units. Rounding out the ten top sellers were the Nissan Sentra (8,399 units), Mazda3 (7,647 units), Dodge Dart (5,617 units) and Subaru Impreza/WRX (4,923 units). The Kia Forte (4,706 units) and Volkswagen Golf (2,249 units), eleventh and twelfth respectively, have fallen behind.
