Will Mazda show the next Miata's chassis in NY?

Mazda is being very sneaky about what it is bringing to the New York Auto Show, and it might have something to do with the next-generation MX-5 Miata. Australian website Motoring.com.au spoke to a company insider who told it that at least the chassis for the roadster would debut in Manhattan. The rumor goes that the show will act as the kickoff for the PR campaign for the new model.
We contacted Mazda USA PR Director Jeremy Barnes to find out more, and he would neither confirm nor deny the rumor. "Just because you read it on the Internet doesn't mean you should repeat it," he said to Autoblog. That's not exactly an outright, No.
Supporting evidence that the new drop top might be appearing in the Big Apple includes Mazda's plan to celebrate the model's 25th anniversary at the show. It's bringing 15 cars from the first three generations to display. "It will be absolutely worth attending the New York Auto Show if you're a Miata fan," Barnes said. That at least hints that there might be something he's not telling us. Otherwise it's a lot of sizzle without much steak.

Mazda Hazumi Concept previews next Mazda2 in Geneva [w/videos]

The official photos of Mazda's Hazumi concept leaked out yesterday, but we have finally gotten to see it in real life at the Geneva Motor Show. Our view is that its Kodo lines looks as good on the diminutive car's sheet metal as they did in photos.
The Hazumi was designed to appear to be bursting with energy, and it seems to deliver. While Mazda refuses to actually say that this is the concept for the next Mazda2, it makes it clear that the little hatchback is "foreshadowing Mazda's next-generation subcompact car." We can all read between the lines.
Hazumi also introduces the new Skyactiv-D 1.5-liter diesel engine but details about it are scant at the moment. The specs for the engine are still unannounced, but the company promises that it is both very efficient and has lots of torque for its size. Mazda is also promising that its Mazda Connect infotainment system will be available in the car too. Scroll down for the brief press release a brace of videos that celebrate the tiny concept's arrival.

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.
