Next Mazdaspeed3 could look this good

Mazda showed off its brand-new 2014 Mazda3 at an event in New York City earlier this week, and we have to say, at first blush, we're pretty impressed. It looks fantastic - like a smaller, hatch'd version of the already sleek Mazda6 sedan that went on sale earlier this year. And with a 200-pound weight reduction, efficient Skyactiv gasoline engines underhood and Mazda's usual focus on driving dynamics above all, we're willing to bet that the new Three will be a pretty decent steer.
Of course, being enthusiasts, we're already setting our sights on the next-generation Mazdaspeed3, rendered here by artist Theo Chin. To our eyes, it's not a very imaginative transformation, but is likely a spot-on rendering for what the next car will look like. And it's really, really hot.
While Mazda hasn't exactly confirmed that the new Speed3 will be coming, sources within the automaker have indicated that a third-generation version of the MS3 is under development. Thing is, the Japanese automaker wants to give the standard Mazda3 some time to grow in the market, so we might not see the new Speed3 until something like 2016, with a possible diesel version to arrive before then.

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.

New Mazda CX-4 teaser shots emerge ahead of Beijing debut

The Kodo styling language seen on last year's Koeru concept seems to translate well to a production car, judging by these teaser images of the upcoming CX-4 from Mazda's Chinese press site. And, as has been seen on several recent Mazdas, concept cars can be quite close to their eventual production versions. An earlier press release implies the CX-4 should be seen as a more coupe-like counterpart to the CX-5, with some of the MX-5's characteristic and often emphasized jinba ittai feel injected into it – if the MX-5 is all about the rider and horse being one, the CX-4 would just be a slightly bigger steed. The 19-inch wheels and LED headlights are some of the more attention-grabbing details on the car. Inside, there's a head-up-display and a MZD connect infotainment screen as seen on other current models. The hardware on the "Exploring-Coupe SUV", as Mazda call it, should match the CX-5: 2.2-liter SKYACTIV-D turbodiesels in some markets, 2.0 and 2.5-liter SKYACTIV-G gasoline engines in most. There will also be a choice of front-wheel-drive or all-wheel-drive. The Beijing Motor Show opens to the public on April 29th, so we won't have to wait a whole lot longer to see the whole thing.
