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.

U.S. and Toyota Reach Settlement Over Safety Problems Disclosure

The U.S. has reached a $1.2 billion settlement with Toyota Motor Corp., concluding a four-year criminal investigation into the Japanese automaker's disclosure of safety problems, according to a person close to the investigation. Attorney General Eric Holder, Transportation Secretary Anthony Foxx and U.S. Attorney for the Southern District of New York, Preet Bharara, were announcing the settlement Wednesday morning, said the official, who spoke on condition of anonymity because the official was not authorized to discuss the settlement on the record before the announcement. TOP 5Most Researched Green Cars On AOL Autos 2013 Honda Fit EV MSRP : $36,625 2014 Chevrolet Spark EV MSRP : $26,685 2012 Mitsubishi i-MiEV MSRP : $29,125 2012 Ford Focus Electric MSRP : $39,200 2012 Toyota Prius Plug-in MSRP : $32,000 In a statement early Wednesday, Toyota said it has "cooperated with the U.S. Attorney's office in this matter for more than four years" and had "made fundamental changes to become a more responsive and customer-focused organization, and we are committed to continued improvements." The criminal investigation focused on whether Toyota was forthright in reporting problems related to unintended acceleration troubles. Starting in 2009, Toyota issued massive recalls, mostly in the U.S., totaling more than 10 million vehicles for various problems including faulty brakes, gas pedals and floor mats. From 2010 through 2012, Toyota Motor Corp. paid fines totaling more than $66 million for delays in reporting unintended acceleration problems. The National Highway Traffic Safety Administration never found defects in electronics or software in Toyota cars, which had been targeted as a possible cause. The settlement continues a string of bad publicity for Toyota, which before the unintended acceleration cases had a bulletproof image of reliability. Since the cases surfaced, the company's brand image has been damaged and it has lost U.S. market share as competition has intensified. Last year, Toyota agreed to pay more than $1 billion to resolve hundreds of lawsuits claiming that owners of its cars suffered economic losses because of the recalls. But that settlement did not include wrongful death and injury lawsuits that have been consolidated in California state and federal courts. In December, Toyota filed court papers after a four-year legal battle saying that it's in settlement talks on nearly 400 U.S. lawsuits, but other cases aren't included in the talks.

2015 Toyota Sienna goes overboard to promote a SpongeBob movie

Good marketing is a huge portion of making a film successful, and Toyota and Nickelodeon are going overboard to promote the upcoming SpongeBob Movie: Sponge Out of Water with this custom 2015 Sienna inspired by the cartoon character at the Los Angeles Auto Show. The exterior is decorated to look just like SpongeBob, but his maniacally smiling face on the hood and windshield might be pure, uncut nightmare fuel for a segment of the child population. The ring on the roof actually blows bubbles too, and the look gets finished off with matching blue and yellow wheels. If you get past SpongeBob's crazed expression and take a peek inside, you find even more cartoon cues. Each of the seats is upholstered to evoke the shows stars, and all of the trim has nautical inspiration as filtered through the series' animation style. The floor is a sandy beige, blue wood trim runs over the dashboard and sides and the roof has airbrushed clouds. Of course, it's hard not to miss a ship's wheel that replaces the usual steering wheel. While it's certainly bizarre, kids might dig the bright colors, while their parents check out the Sienna. The van's also going on a cross-country promotional tour to advertise the movie ahead of its February 6 release. Scroll down for all of the info about this cartoon car.
