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.

Mazda Miata livery design contest in Forza Horizon 2

If you're into video games, creativity, the Mazda MX-5 Miata and South by Southwest, then there's a contest in Forza Horizon 2 you'll want to know about. Called the Livery Design Contest, your job is to head to Xbox Live sometime before midnight on January 4, 2015 and design a paint job for the 1994 Miata in the game. A panel of judges will evaluate designs for originality, aesthetic design and technical proficiency, and settle on up to five semifinalists who will regroup in the next round, which is public voting. Come January 26, the public can begin voting on its favorite design until February 12, to narrow the semifinal pool down to two. Those two will be flown to South by Southwest in Austin, TX – which happens from March 13-22 – and one of them will be crowned the winner. Said winner will lumber away from the event with $3,500 worth of prizes, including a 55-inch curved-screen television, and their livery will be free to all of the minions playing Forza Horizon 2. There's also a Mazda hub on Xbox Live for everyone to take an in-depth look at the 2016 Miata, if you just like to watch, in which case you may also want to see the related videos joining the press release below. MAZDA TEAMS UP WITH XBOX TO LAUNCH 2016 MX-5 - Mazda MX-5 Livery Design Contest Now Live in Forza Horizon 2 - - Branded hub allows Xbox users to virtually tour 2016 MX-5 and enter MX-5 design contest - Winning design to be featured in Forza Horizon 2 and gifted to all players IRVINE, Calif. (December 4, 2014) – For the second consecutive year, Mazda North American Operations (MNAO) is teaming up with Xbox, this time to promote the launch of the 2016 Mazda MX-5 and give Forza Horizon 2 players the chance to enter the Mazda MX-5 Livery Design Contest. An interactive experience with the 2016 Mazda MX-5 and information on the design contest will be available through the Mazda branded hub on Xbox 360 and Xbox One. The Mazda MX-5 Livery Design Contest, which is now live through January 4, 2015, will give Forza Horizon 2 players the opportunity to design the livery for the 1994 Mazda MX-5 currently available in-game. Two finalists will be awarded a trip in March to South by Southwest 2015 for the final design showdown. The winner will walk away with a new 55-inch curved TV, audio music system, Xbox One Kinect console and one MadCatz Racing Wheel estimated at $3,499.95.

Next Mazda CX-9 to launch by 2016, could get turbo-four

Mazda has a lot going on these days, what with launching the new Mazda6 and Mazda3, with the new Mazda2 just around the corner. We know the new Miata is also on the way, and after that it looks like the next vehicle in its lineup due for an overhaul is the CX-9 crossover, due to launch by 2016. The move makes sense because the CUV is growing long in the tooth. It was first introduced in 2007 and was refreshed twice since then.
The next-generation CX-9 will move away from Ford-derived components like the V6 in the current model and will likely use a turbocharged four-cylinder engine. However, a final decision hasn't been made yet. "If I ask Mr. Hitomi, our top guy of powertrains at Mazda, he believes the downsizing turbo solution costs more. But real downsizing means six-cylinder to four-cylinder turbo could make sense from a cost point of view," said Mazda's global marketing boss Masahiro Moro to CarAdvice at the New York Auto Show. The executive said a hybrid powertrain option would be unlikely, but markets outside the US could get a diesel, as well.
Moro also tipped his hand at future Mazda model plans. He hints that the Japanese automaker is considering building a luxury vehicle with a six-cylinder engine. "It's too early, we don't have a car yet. But we are collecting advice as to V6 or straight-six," he said to CarAdvice. We'll definitely be watching.
