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.

Chip maker Nvidia adds Volvo to list of self-driving partners

Chipmaker Nvidia Corp announced on Monday it was partnering with Volvo Cars and Swedish auto supplier Autoliv to develop self-driving car technology for vehicles due to hit the market by 2021. Volvo is owned by China's Geely Automobile Holdings. Silicon Valley-based Nvidia also announced a non-exclusive partnership with German automotive suppliers ZF and Hella for artificial intelligence technology for autonomous driving. Nvidia came to prominence in the gaming industry for designing graphics processing chips, but in recent years has been a key player in the automotive sector for providing the so-called "brain" of the autonomous vehicle. The company, whose many partners already include Tesla, Toyota, Ford, Audi, BMW, and tier one supplier Robert Bosch, announced its latest deals at an automotive electronics show in Ludwigsburg, Germany. Nvidia's Drive PX artificial intelligence platform is used by Tesla in its Models S and X and upcoming Model 3 electric vehicles. Volkswagen AG's Audi is also using the system to reach full autonomous driving by 2020. In a call with reporters, Nvidia's senior automotive director Danny Shapiro said carmakers and their main suppliers are now moving away from the research and development phase of autonomous vehicles and into concrete production plans. The system developed jointly by ZF and Hella, and using Nvidia's Drive PX platform, will combine front cameras with radar and software to create technology meeting the Euro NCAP safety certification for so-called "Level 3" driving, in which some, but not all, driving is performed by the car. Volvo is already using the Drive PX for the self-driving cars in its "Drive Me" autonomous pilot program. Volvo's production vehicles built on Nvidia's platform, as announced on Monday, are planned for sale by 2021.Reporting By Alexandria SageRelated Video: Auto News Green Tesla Toyota Volvo Technology Emerging Technologies Autonomous Vehicles nvidia autoliv

Toyota teases mysterious RND Concept

Toyota is being very secretive about its newly teased RND Concept. The image above is all that the Japanese automaker is showing at the moment, and it's not much to go by. However, the wait to find out won't be very long, as the automaker is unveiling this very mysterious vehicle on January 26 in the UK. Making the RND even more intriguing is that this isn't just a concept pointing the way towards some nebulous future vehicle. Toyota claims that the model is production ready, and the automaker already has pricing, supply and manufacturing space prepared. We likely shouldn't expect a super luxury sedan or sports coupe, though, because Toyota says that the RND is meant for "the widest possible market." Could it possibly be some sort of inexpensive, electric vehicle like the Renault Twizy, then? With just the hind of a taillight, a slash of chrome and what might be an intake, there's not much styling work to go on here. Although, Toyota is making huge promises about the design; it claims the RND "has the potential to transform the look of every vehicle on the road." It's odd to see an automaker other than Tesla reveal a new vehicle outside of a major world auto show, which piques our interest about what Toyota is doing here. Read the company's press release below and let us know what you think the Japanese automaker is up to in Comments. THE NEW TOYOTA RND CONCEPT: SNEAK PREVIEW First details of new model released ahead of world debut next week Toyota is breaking with motor industry convention by revealing a new product outside the familiar surroundings of an international motor show. Instead its new RND Concept will make its world debut in the UK on 26th January, ready for fast-track development that should see it changing the face of motoring within weeks. The first image released today hints at how the concept's design marks a radical shift in direction for Toyota, taking the "fun-to-drive" qualities of its cars to a higher level. Although presented as a concept, Toyota acknowledges the RND will be unveiled in its production-ready form. Manufacturing and product supply have been secured and on-the-road pricing has been fixed at a level that will make the RND Concept accessible to the widest possible market. Toyota is confident, too, that the RND Concept's impact will go far beyond its own model range, having the potential to transform the look of every vehicle on the road.
