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.

Feds investigating Mazda CX-9 over suspension problems

The National Highway Traffic Safety Administration is opening a preliminary evaluation into the 2007-2008 Mazda CX-9 because the lower ball joint in the front suspension can potentially separate while driving. An estimated 54,000 examples of the crossover might be affected. The investigation was prompted by six complaints of this happening on the road. Because the complaints are coming more rapidly as of late, NHTSA thinks the issue could be getting worse. The problem also appears to be more prevalent in states that use salt on their roads in the winter. None of the failures caused any injuries, and all but one happened at 20 miles per hour or slower. NHTSA's preliminary evaluations "assess the scope, frequency, and safety consequence" of a potential problem and can sometimes lead to recalls.

SUMMARY: The Office of Defects Investigation (ODI) has received six (6) complaints (VOQs) alleging incidents of front suspension LBJ separation in MY 2007 through 2008 Mazda CX-9 vehicles. The reports appear to show an increasing trend. One of the separations allegedly occurred at 40 mph and the other 5 incidents occurred at speeds between 0 and 20 mph. The first VOQ was received in October 2013, followed by 2 reports in late 2014 and 3 reports in the first 5 months of 2015. Four of the VOQs are from states using high volumes of road salts (?salt states?) which, for purposes of this investigation, include: Connecticut, District of Columbia, Delaware, Illinois, Indiana, Iowa, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, Vermont, West Virginia, and Wisconsin. The other VOQs were from northern Virginia, which borders the ?salt state? region, and South Carolina. ODI also identified EWR field report data related to the alleged defect in the subject vehicles. A preliminary investigation is being opened to assess the scope, frequency, and safety consequence of the alleged defect. The six VOQs associated with this investigation are: 10717510, 10714469, 10695142, 10668978, 10640541, and 10546535.

2016 April Fools' Day: Morgan digs at Tesla, Mini's scissor doors, more

Every year automakers go out of their way to come up with gags for April Fools' Day. Sometimes the jokes fall flat, but occasionally a company really nails it with an idea that we'd actually love to see. Rather than scouring the Web for all of these stunts, you can find some of our favorites right here. Morgan MOGrod The Morgan Motor Company's MOGrod is one of our favorite April Fools' jokes so far this year because it's a car we wish could be real. The company says on Twitter that the retro hot rod uses a 3.7-liter Ford V6, and there are already 250,000 preorders, which is a play on the huge number of reservations for the Tesla Model 3. Morgan took the joke even further by sketching a landspeed record version for the Bonneville Salt Flats. Mini Scissor Doors The people at Mini apparently have a lot of free time because the company has two gags this year. The first is the scissor door option. The idea cleverly plays on the myriad ways customers can customize their Mini, but this solution doesn't look like anyone could easily enter the car due to the way these doors open. Mini Hipster Hatch There's also the Hipster Mini, which is a much funnier idea. This fictional hatchback would be perfect for fashionable Millennials thanks to features like Instagram-filter windows and a fixed-gear drivetrain, which limits the top speed to 25 miles per hour. The interior uses stonewash denim upholstery and packs a twin-deck cassette player. Skoda Dog Umbrella People love dogs, and owners know that a wet canine can be a mess. Skoda is ready to tackle this problem with an umbrella for your mutt. Made from unobtainium, the gadget hides in the door when not in use, but when raindrops start falling, people can keep their pup dry. Skoda Snowman Skoda's Facebook page also teases us with a very cool vehicle. The Snowman is a 396-horsepower plug-in hybrid snow machine. With its tracks, the company's newest model would never have to worry about getting stuck in the winter. Opel Adam C Sure, electricity and hydrogen are cleaner forms of fuel than gasoline or diesel, but Opel has a way to make your car even more environmentally friendly – muscle power. Wind up the crank at the rear for 15 minutes, and the Opel Adam C is good for 125 miles. GM's European division also claims that owners get a great workout because a full winding session burns 400 calories. You wouldn't feel guilty about picking up that pizza after cranking up this hatchback.
