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.

Finalists for 2014 Green Car of the Year announced

The list of finalists for the 2014 Green Car of the Year has been announced, and in a genuinely bizarre twist, there's only one hybrid and no electric vehicles among the five contestants, despite the arrival of cars like the BMW i3 and Tesla Model S. Taking the place of the EVs are a pair of diesels, repping a technology that last won a Green Car of the Year award in 2009, when the Audi A3 TDI took the title. No diesel was in the running for last year's award.
Naturally, both of the diesel finalists are fielded by the Germans - with BMW's 328d and Audi's A6 TDI getting the nod. In the case of the 3 Series, BMW installed a 2.0-liter, turbodiesel, capable of delivering 180 horsepower and 280 pound-feet of torque, while returning 45 miles per gallon on the highway. Audi and its larger, 3.0-liter, V6 turbodiesel produce quite a bit more grunt, with 240 hp and 428 lb-ft of grunt, but net a very impressive 38 mpg on the highway in the A6.
Finalists for this year's awards include two diesels, three gas-powered cars and a plug-in hybrid.

2019 Mazda CX-9 Review and Buying Guide | Fun for the whole family

The 2019 Mazda CX-9 crossover is the biggest vehicle in the Japanese automaker's lineup, and the only one to offer a third row of seating. It has only one powertrain option, but offers a wide variety of other content across various trim levels. Many folks are drawn to Mazdas for their elegant design, affordability and driving dynamics that are sharper than most, and the CX-9 has all of that to a certain degree even if it's the biggest, most family-oriented one. Still, the CX-9 may be big for a Mazda, but it's one of the smallest in its segment in terms of third-row space and cargo capacity, so it may not be for every family. What's new with the Mazda CX-9 for 2019? Though largely unchanged from when this generation debuted for the 2016 model year, the Mazda CX-9 gets a few small changes for 2019, the biggest of which is the addition of Apple CarPlay and Android Auto compatibility, which is optional on its lowest Sport trim and standard on the Touring, Grand Touring, and Signature. The transmission has been retuned for a smoother, quieter driving experience. Thicker floor mats and headliner further help to make the car quieter. Each trim gets a little something new, too. Sport now offers an optional Sport Package, costing $1,290, with heated front seats, a power driver's seat, heated mirrors, lane-keep assist, adaptive cruise control and automatic emergency braking. Moving up to the Touring trim, the only other change is a frameless rear-view mirror. The Grand Touring trim gets a new 7-inch info screen in the instrument panel, along with new power-folding side mirrors and a 360-degree camera system. The top-level Signature trim gets new badges, rosewood interior trim, and accent lighting in the grille and around the shifter. Along with the new features, the CX-9 increases in price. The Sport trim costs a mere $150 more, the Touring and Grand Touring trims go up by $370, While the Signature jumps $1,050 compared to the 2018 model. What are the CX-9's interior and in-car technology like? The interior varies by trim level, but with Mazda making moves to grab customers from some of the luxury brands on its "path to premium," the higher grades do look and feel like a high-quality, comfortable place to spend time. It's a spacious interior with room enough for a third row. There are some rally nice materials in use, depending on the trim level, including Nappa leather and something called Santos Rosewood.
