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 has two all-new 8-passenger SUVs in the works, and one's a Lexus

Toyota announced yesterday that its Princeton, Indiana, manufacturing plant is getting a big $803 million infusion of cash. The reason? Toyota casually dropped that it will soon build “two all-new, three-row SUVs” there. TheyÂ’ll be “designed with the active Gen Y American Family in mind,” which is another way of saying that Toyota is targeting Millennials. In case you missed it, Millennials are in their late 20s and 30s now! That means they have growing families and need more space to put them. Both new SUVs will seat up to eight passengers. The other big reveal is that both will be electrified. WeÂ’re going to assume that means theyÂ’ll be regular hybrids in ToyotaÂ’s case, though thereÂ’s every possibility for a PHEV “Prime” version, too. Both will have semi-automated driving systems, advanced enough that they will “allow for hands-free driving in certain conditions.” Plus, there will be a remote parking system that allows “the driver to park and unpark outside the vehicle using a smartphone.” The last nugget of tech Toyota is sharing with us is that both will use a new “digital key” that turns your smartphone into a quasi key and allows you to share it digitally with others. Another bit of information concerning these two is that one will be a Toyota, and the other will be a Lexus. What these two models will be named is not yet clear. Seeing “three-row SUV,” our minds instantly go to Sequoia. That model is as old as it gets these days, and is deeply in need of a redesign — the current generation launched all the way back in 2008. However, Toyota does not explicitly say that this news pertains to the next-gen Sequoia. In fact, previous reports of the Sequoia shifting its production location to San Antonio lead us to believe that this news has absolutely nothing to do with a potential next generation of the SUV. Coincidentally, the Sequoia is currently built at the Princeton, Indiana, plant thatÂ’s getting this investment — that official switchover to Texas is reported to happen sometime in 2022.  ToyotaÂ’s language in this press release, plus the knowledge that Sequoia is leaving Indiana, all indicates that these two three-row SUVs might not be rough-and-tumble body-on-frame off-roaders. TheyÂ’re likely going to be plenty capable (hitting that “active lifestyle” market), but the focus toward families suggests that comfort could be paramount.

Toyota's Bob Carter says far fewer stations needed in shift from gas to hydrogen

Toyota's Bob Carter has been talking about green cars for years, but it's only been recently that his comments have really caught widespread attention thanks to his disparaging remarks about electric vehicle supporters like Elon Musk and Carlos Ghosn and optimism about hydrogen. Speaking at the opening of the Chicago Auto Show this morning, Carter said that Toyota has claimed the "pole position on CAFE," thanks to its deep hybrid bench. The company's green car cred will continue to grow because of its upcoming hydrogen fuel cell car, due out next year. Carter is relentlessly optimistic: "I truly believe fuel cells will fundamentally change how we feel about transportation," he said. The reason, Carter said, is that a hydrogen infrastructure will be easier to install than people think. He referenced a study conducted by the University of California (which we've heard about before) that found that California would only need 68 hydrogen stations to refuel the roughly 10,000 H2 vehicles that Toyota hopes to sell in by 2016 or so. That's a lot more than the nine that exist today, but the state has already approved funding for 20 new stations by 2015 and then up to 100 by 2024. Then he said this: "If every vehicle in California ran on hydrogen, we could meet refueling logistics with only 15 percent of the nearly 10,000 gasoline stations currently operating in the state." "We could meet refueling logistics with only 15 percent of gasoline stations currently operating in CA" - Bob Carter This made us wonder: if the refueling time and range are roughly equivalent between hydrogen and gasoline – Toyota's hydrogen car is supposed to be able to go 300 miles on a five-minute fill-up - then why has the market decided that there should be 10,000 gas stations in California and why would 1,500 be sufficient for hydrogen? "If the locations are optimized," he said, "we don't need 10,000 stations." For example, at major intersections, instead of three gas stations, you'd really just need a single hydrogen one. "There are a lot of questions about the infrastructure, but it's coming. ... It's a hurdle that we've got to climb but it's not as steep as some may imagine." Toyota's Mike Michaels, the national manager, media and public affairs at Toyota Motor Sales, then stepped in to point out that there are gas stations closing and admitted that there might be too many gas stations in California.
