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.

Sweating the small stuff | 2017 Mazda CX-5 First Drive

The 2017 Mazda CX-5's door handles got their own design study. They got their own graphs, maths, and a team of people scientifically analyzing how humans interact with them. There was a whole to-do. And yet, you look at them back-to-back with their predecessors, a Spockian eyebrow reaching to the stars, and wonder what all the fuss was about. But apparently they're better. They're also perfectly illustrative of the entire effort to re-engineer and improve Mazda's best-selling model. At first, the 2017 Mazda CX-5 seems like a sensible evolution of its well-loved predecessor – there's sexier styling, a more premium cabin, and additional features, but the dimensions and engine specs look awfully similar. It certainly looks like one of those "the old car's great, let's not overthink the new one" redesigns. Except it isn't. Dig deeper and you'll see just how much meticulous work – from the door handles to the throttle response – went into making the new CX-5 a crossover that thoroughly trounces the majority of its competition. Take the efforts to make it quieter. According to Mazda's internal measurements, the sound-quelling improvements made for the CX-5's 2016 refresh already made it one of the quietest compact SUVs on the market. That apparently wasn't good enough. To what seems like an absurd degree, Mazda's engineers obsessively examined every nook, cranny, corner, and crevice to sniff out noise and eliminate it. Gaps were filled, insulation was injected, seals were added, air was redirected, glass was double glazed, and carpet replaced plastic coverings. It would seem that the Society of Persnickety Engineers is well represented at Mazda HQ. "I'm not sure how they found some of these," said Mazda vehicle development engineer Dave Coleman with a shake of his head, almost amused by the obsession and dedication of his colleagues across the proverbial hall in the sound-deadening department. (He goes over many of their enhancements in the video below.) And it worked. The new CX-5 is indeed incredibly quiet, even on San Diego's notoriously loud corrugated concrete freeways. It is quiet for a Mazda – a brand previously known for the exact opposite – and the entire segment. Even the fairly quiet 2017 Honda CR-V we drove on the same freeways on the way to San Diego couldn't match it. Actually, much of the driving experience can't be matched by a competitor.

Toyota, Mazda get an Alabama welcome for $1.6 billion plant

MONTGOMERY, Ala. — Toyota and Mazda confirmed Wednesday they will build a $1.6 billion joint venture assembly plant in Alabama that will employ up to 4,000 workers, a boost for President Donald Trump who wants automakers to expand U.S. production. Toyota President Akio Toyoda and Mazda President and Chief Executive Officer Masamichi Kogai joined Alabama Gov. Kay Ivey in Montgomery at an event to confirm the decision. "Welcome to sweet home Alabama," Ivey said to the two executives, after saying that the anticipated 4,000 workers at the plant to be built in Huntsville would earn an average of $50,000 a year. The plant will produce 300,000 vehicles a year and should open on a 2,500-acre former cotton field in 2021, about 14 miles from Toyota's engine plant in Huntsville. Toyota plans to build Corolla cars at the plant, while Mazda will build crossover SUVs. "Together, I am confident we will create yet another 'Built in America' success story," Toyoda said. Alabama will provide tax incentives. Officials said the state tax incentives were worth $370 million, but they did not disclose how much the local incentives were worth. Huntsville Mayor Tommy Battle said the plant will "provide jobs for decades to come for Huntsville and Alabama. It vaults Alabama to the top as an industry leader in producing the next generation of cars that will power our nation." Among U.S. states, Alabama is already the fifth largest producer of cars and light trucks. The state has more than 150 major auto suppliers and 57,000 automotive manufacturing jobs. Two decades ago, Alabama spent an estimated $250 million to woo Daimler AG's Mercedes-Benz to put an auto plant in Tuscaloosa, sparking the birth of auto production in the state. In September, Daimler said it would invest $1 billion to expand its Alabama Mercedes-Benz plant to start building electric sport-utility vehicles there from about 2020. Alabama is also home to assembly plants operated by Honda and Hyundai. A Kia assembly plant operates near the Alabama border in Georgia. Mazda and Toyota said they still need approvals and authorization by antitrust agencies for the new joint venture. They announced a capital alliance in August and plans to jointly develop technology for electric vehicles. Trump tweeted in March he wanted "new plants to be built here for cars sold here." Many automakers have announced expansions of facilities or new jobs but no other new U.S. auto plants have been announced. U.S.
