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.

2016 Mazda CX-9 caught on video

We already know from earlier spy shots that the second-generation Mazda CX-9 is advancing in development, but here's an opportunity to actually see the crossover on the road. The video shows the CX-9's rear, but wait 50 seconds for a good look at it in profile and from the front. The CX-9 is no longer wearing the same camouflage from the last spy photos, but this time it has more cladding to hide the lines. Even with the obfuscation, you can still get a sense of the general shape. The CUV largely looks like a stretched version of the CX-5, which is a great place to start. Rumors suggest the new CX-9 will debut in November at the 2015 Los Angeles Auto Show and to launch in 2016 for the 2017 model year. Power is tipped to come from a turbocharged, 2.5-liter Skyactiv four-cylinder, and all-wheel drive is expected to be available. Related Video:

2015 will be the biggest year ever for cars at CES

Like the SEMA Show, major automakers are paying increasing attention to the CES, with 2015 expected to be one of the most auto focused yet. Ford, Volkswagen, Toyota, General Motors, Hyundai, Mazda, Audi, BMW and Fiat Chrysler Automobiles will all be in attendance when CES 2015 kicks off next week, taking up a record-breaking 165,000 square feet of space at the Las Vegas Convention Center. "We've come a long way from a single car on a carpet," Ford's Alan Hall told Bloomberg. Unlike SEMA, or a more traditional auto show, like the upcoming festivities in Detroit, CES doesn't necessarily focus on entire cars or the way they perform, but on the way our technology will interact with vehicles, and in how those vehicles will deliver information to drivers. "CES has become a major launch point for a lot of the big automakers," IHS tech analyst Mark Boyadjis told Bloomberg. "CES is a way for them to get on a global stage for technology." As for what kind of wares automakers will trot out in Las Vegas, we already know that BMW will show off an autonomous i3 electric car that can navigate its way through a multistory car park and can be hailed via a smartwatch app. According to Bloomberg, Hyundai will show off its own smartwatch app for the Genesis sedan, while Audi and Mercedes-Benz will show off autonomous vehicles next week. Automakers won't be the only companies looking to capitalize on CES. Tech firms, like chipmaker Nvidia, are becoming increasingly involved in the automotive game and will be in town showing their wares off to OEMs. "Two years ago, our booth would have been filled with PCs and people playing video games," Danny Shapiro, Nvidia's senior director for automotive business, told Bloomberg. "This year we made a strategic decision to shift the focus of the booth on automotive and de-prioritize some of the other things." Needless to say, you can expect to see a lot of news out of Las Vegas come next week. Stay tuned.
