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 nudges US sales projections up to 2.25M

Toyota has raised its expectations for 2013's US sales for the third time since the end of 2012. The new target rests at 2.25 million units, when sales of Toyota, Lexus and Scion are taken as one. Subtracting Lexus, Toyota is still expecting to move over two million vehicles in the US by the end of 2013.
According to a report from Automotive News, the sales expectations came from Bob Carter, senior VP of automotive operations for Toyota USA, during a dealers during a meeting in Atlanta. The heightened expectations go along with Toyota's predictions for the US market as a whole, which it expects to grow to 15.5 million units by the end of 2013.
Besides an overall, national uptick in new vehicle sales, Toyota is also expecting a big push as it puts the next-generation Corolla to market during the second half of this year, along with the Tundra pickup truck. Meanwhile, dealers were shown images of a refreshed Camry, set to arrive in 2015, and reported that it's "more than a nip and a tuck," according to the AN report.

2016 Toyota Tacoma teased again

Toyota is following up its muddy teaser of the back of the 2016 Tacoma with a dusty new one that shows the truck's face for the first time. Without seeing more of the pickup, it's impossible to make any educated judgments, but the company appears to be taking the Taco's styling in a new direction. The 2016 Tacoma features a hexagonal grille outlined in chrome and a narrow intake underneath visually connecting the foglights. The headlights take on a squinting look, and this shot suggests LED running lights at the outer edge (perhaps just for top-level trims). You can also just make out a bit boxier of a flare for the front fender. The truckmaker hasn't announced anything about the Tacoma's powertrain, but we spied a prototype testing several months ago with a six-speed manual transmission. That one reportedly rode on a modified version of the current model's frame, as well. Toyota apparently has high hopes, though, because it's ramping up production at the Taco's factory in Mexico by 41 percent. The truck debuts at the 2015 Detroit Auto Show on January 12, and you can read Toyota's to-the-point press release about it below. See. The. Light. December 17, 2014 The lights come on and Tacoma rolls at the 2015 North American International Auto Show. The all-new 2016 beast hits the stage at 12:50 p.m. EST, Monday Jan. 12.
