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 Tacoma helps stand up to your girlfriend, mimes, magicians and the Grim Reaper

It takes a lot to get a product noticed in today's fast-paced world, but one avenue that's always seemed to grab the eyeballs of consumers has been humor. Toyota knows this rule well, and has put together a quartet of spots called "Tacoma Wins," in which the midsize pickup's features and specifications best a number of seemingly worthy competitors.
Whether it be sobbing girlfriends, a circus magician, a grim reaper or the scariest thing of all, a mime, the Tacoma looks well equipped to deal with it. Take a look below for all four of Toyota's newest spots.

Toyota teases 2016 RAV4 Hybrid for New York Auto Show

Toyota is being extremely enigmatic with its tease for the newly announced RAV4 Hybrid. The Japanese automaker merely has a photo of the model's rear end with a visible hybrid badge on it. The only additional into tells us to look forward to the CUV's debut in just a few days at the New York Auto Show on April 2. Thankfully, Toyota's teaser shot does give away a few more details about this new version of the RAV4. The LED taillights on display aren't the regular ones that wrap around the back of the popular crossover. In the current design, the white portion is placed near the middle of the hatch, and there's amber at the corner. Here, the indicator is clear and two strips of lights run towards the center. The automaker has made its plan clear to sell even more crossovers in the near future, and the RAV4 has already been a strong mover for Toyota. The company shifted 267,698 of them in 2014, a year-over-year jump of 22.7 percent. Through February 2015, it has sold 41,767 examples of the CUV, a 25.3-percent improvement over the same period last year. Still, the decision to launch a hybrid version of the RAV4 now is a bit surprising. The US market for the green segment was soft last year, and it hasn't really turned around yet. Although, rumors of Toyota launching a greener variant of its popular CUV have been around for years. At that time, the company said it would monitor market demand, and maybe the people have spoken.
