2014 Mazda6 recalled due to fuel overfill fire risk

Mazda is recalling 19,000 Mazda6 sedans from model year 2014, over concerns that the fuel tanks can be filled up too much. What is it with Mazda and fuel tanks?
The big concern is, obviously, spillage when filling up. There's also a risk that a radical temperature swing could cause the fuel volume to expand, causing a full tank to spill over without the driver knowing about it. According to the National Highway Traffic Safety Administration bulletin, if the fuel spills over, it could end up in something called the charcoal canister, which helps with the car's emissions. If it fills up the canister, it could leak out onto the road. None of this is really desirable.
The affected vehicles were all built between October 25, 2012 and May 9, 2013. It's unclear if there have been any fires due to this problem. Dealers should have been notified by now, while owners should begin receiving official recall notifications very soon.

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.

Japan could consolidate to three automakers by 2020

Sergio Marchionne might see his dream of big mergers in the auto industry become a reality, and an analyst thinks Japan is a likely place for consolidation to happen. Takaki Nakanishi from Jefferies Group LLC tells Bloomberg the country's car market could combine to just three or fewer major players by 2020, from seven today. "To have one or two carmakers in a country is not only natural, but also helpful to their competitiveness," Nakanishi told Bloomberg. "Japan has just too many and the resources have been too spread out. It's a natural trend to consolidate and reduce some of the wasted resources." Nakanishi's argument echoes Marchionne's reasons to push for a merger between FCA and General Motors. Automakers spend billions on research and development, but their competitors also invest money to create the same solutions. Consolidating could conceivably put that R&D money into new avenues. "In today's global marketplace, it is increasingly difficult for automakers to compete in lower volume segments like sports cars, hydrogen fuel cells, or electrified vehicles on their own," Ed Kim, vice president of Industry Analysis at AutoPacific, told Autoblog. Even without mergers, these are the areas where Japanese automakers already have partners for development. Kim cited examples like Toyota and Subaru's work on the BRZ and FR-S and its collaboration with BMW on a forthcoming sports car. Honda and GM have also reportedly deepened their cooperation on green car tech. After Toyota's recent buyout of previous partner Daihatsu, Nakanishi agrees with rumors that the automotive giant could next pursue Suzuki. He sees them like a courting couple. "For Suzuki, it's like they're just starting to exchange diaries and have yet to hold hands. When Toyota's starts to hold 5 percent of Suzuki's shares, this will be like finally touching fingertips," Nakanishi told Bloomberg. "I absolutely do believe that we are not finished seeing consolidation in Japan," Kim told Autoblog. Rising development costs to meet tougher emissions regulations make it hard for minor players in the market to remain competitive. "The smaller automakers like Suzuki, Mazda, and Mitsubishi are challenged to make it on their own in the global marketplace. Consolidation for them may be inevitable." Related Video:
