Mazda builds 4-millionth Mazda3

To say that the Mazda3 is a vital product for Mazda would be one heck of an understatement. In fact, the model line accounts for about 30 percent of the manufacturer's sales. Fortunately for Mazda, they're selling well.
These days, the Japanese automaker is building the Mazda3 (known domestically as the Axela) in Japan, China, Thailand and, as of last month, in Mexico. The company's expanded global production capacity has helped Mazda reach four million units of the Mazda3 sold around the world since the first model was introduced over ten and a half years ago.
Over the course of that decade since its introduction in June 2003, Mazda has gone through three generations of Mazda3, the newest model benefiting from the company's Skyactiv technology and even encompassing a hybrid model in the Japanese Domestic Market.

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.

Mazdaspeed3 concept tipped for Frankfurt debut

The last quarter of 2015 could be a big one for Mazda as a report has emerged from Australia claiming that the company will come to the Frankfurt Motor Show in September with a near-production concept of the third-generation Mazdaspeed3, while a second-generation CX-9 will be shown a few months later in Los Angeles. Motoring.com.au ran the initial report, and although the news seems plausible, the outlet doesn't provide sources for either piece of news. Likewise, our friends at Mazda USA refused to comment on "speculation." Speculation it may be, but it's surely tantalizing considering the recent popularity of both the hot hatch and three-row crossover segments. According to the Aussies, the concept Speed3 will quickly evolve into a production model, which will launch alongside a mid-cycle refresh for the current 3. A turbocharged 2.5-liter will spit out 295 horsepower, and could have all-wheel drive. Even if only the front axle is doing the work, the MS3 will easily be able to stand toe-to-toe with hotter half of the segment based on output alone. As for the more mundane offerings, Motoring reports the long-in-the-tooth CX-9 will get a replacement in LA, although it doesn't offer much in the way of details beyond that. It should be interesting to see how the company's Skyactiv philosophy will be implemented on such a large vehicle. Perhaps the biggest surprise from the Australian report, though, are the outlet's reports on the CX-7, which will return sporting a third row of seats after its larger sibling debuts. That'd give Mazda a versatile lineup of four crossovers, with the sub-compact CX-3, the compact CX-5, the midsize, seven-passenger CX-7 and the fullsize CX-9. As we weren't able to confirm any of this with Mazda, we'd still warn that this news should be ingested with grains of salt. Still, it looks like the company could be set to make some waves in the first two shows of the upcoming auto show season.
