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 Toyota Mirai launching in US this October

The small-volume 2016 Toyota Mirai is coming to California in October. That's the news from today's announcement of the eight Toyota dealerships in and around Los Angeles and San Francisco that will be the first to sell the hydrogen car in the US. Previously, all that Toyota said was that the first 200 units would be available in the fall of 2015. Toyota expects to sell a total of 3,000 Mirai hydrogen cars by the end of 2017. The eight dealerships are: San Francisco Toyota, Roseville Toyota, Stevens Creek Toyota, Toyota of Sunnyvale, Longo Toyota, Toyota Santa Monica, Toyota of Orange, and Tustin Toyota. If you're interested in buying a Mirai, you can sign up for more info here. The Mirai starts at $57,500. Toyota is still talking about state and federal incentives that can bring the car to under $45,000, but the federal tax incentive for hydrogen vehicles expired in December. Toyota is asking the government to bring the incentive back. The Mirai will also be available to lease for $499 a month for 36 months (with $3,649 due at signing). Both options come with free hydrogen fuel for "up to three years." Related Video: TOYOTA MIRAI: COMING THIS FALL TO SHOWROOMS NEAR...? Eight California Toyota Dealers Announced Mirai Order Requests Begin Summer 2015 Torrance, Calif. (May 6, 2015) – Want a Mirai? All those in favor, say aye! California trailblazers waiting to get behind the wheel of Toyota's hydrogen fuel cell electric vehicle, the Mirai, now have a destination for pick up and pre-order. In October 2015, Mirai will roll into select Toyota dealerships in the Golden State. Northern California drivers will meet Mirai at San Francisco Toyota, Roseville Toyota, Stevens Creek Toyota or Toyota of Sunnyvale. Farther south, Longo Toyota, Toyota Santa Monica, Toyota of Orange and Tustin Toyota will welcome Mirai customers. These initial dealers were selected based on advanced technology vehicle sales experience and proximity to hydrogen infrastructure. But why wait until October? Beginning this summer, California customers can request a Mirai, by visiting www.toyota.com/mirai. Production of the Mirai is limited and vehicles will be placed with select, eligible customers. Therefore, drivers are encouraged to make their requests early to save a potential parking spot in transportation history. Customers can visit www.toyota.com/mirai today to sign up for more information and notification of exact order request launch timing in the coming months.

Performance cars overpower the Detroit Auto Show

At precisely the stroke of noon on Monday, the 2016 Acura NSX rolled on stage at the Detroit Auto Show amid plumes of smoke and dancing lights. The sounds of the powerful engine revving soared to the rafters. It was the second coming of Acura's iconic sports car, and the reveal had all of the expected trappings. Afterwards, champagne corks popped and the bubbly flowed. It was noon in Detroit, but for the green-car movement, it seemed like the clock had struck midnight. That's an exaggeration, but performance was the overwhelming theme of North America's most important show. Ford – which has helped lead the way in smaller displacement engines and early adoption of hybrid powertrains – had more than 1,500 horsepower on stage one point after it revealed the GT concept, the new F-150 Raptor and the Shelby Mustang GT350R. The NSX is technically a hybrid (it has three electric motors), but with 550-plus hp, there's no doubt this Acura was bred on the track. The theme continued throughout the show at nearly every stand. Alfa Romeo showed off the 4C Spider, which is the open-air version of a car that purports to be the spiritual successor of the high-performance 33 Stradale from 1967. On Tuesday, Cadillac is scheduled to reveal the 640-hp CTS-V with the V8 transplanted from the Corvette Z06, and the Lexus was expected to roll out its own V8-powered beast, the 467-hp GS F. For enthusiasts – especially enthusiasts with money – these are halcyon days. But make no mistake, all of this power has a purpose. Ford product chief Raj Nair said the Blue Oval uses high performance cars to develop technologies, like aerodynamics and materials, which are then shared across its lineup. "It's another proof point about how serious we are in developing innovation through performance," he said. Ford, which is rolling out at least 12 performance cars by 2020, said the sporty cars attract younger and more influential buyers to its fold, which can help burnish its image beyond adding sales volume. Toyota is taking a similar approach, senior vice president Bob Carter said, noting the Lexus RC coupe draws people into showrooms and gets them excited about the brand, even if they don't end up buying one. "They provide an aspiration and a halo that provides the attention that gets you noticed in a cluttered market," he said.
