Next-gen Mazda MX-5 could use carbon fiber to cut weight

The current Mazda MX-5 Miata has only been out for a few years, but the automaker is allegedly looking for ways to lighten the next one. According to a report from Autocar, Mazda is looking to carbon fiber to help the next-generation MX-5 cut weight and use a smaller engine. Despite having more safety features, modern amenities, and a stiffer body, the current MX-5 is the same size as the original sports car from 1990 and weighs less than its immediate predecessor. In a recent interview with Autocar, Nobuhiro Yamamoto, head of the Miata program, revealed that the next generation of the Miata will probably stay the same size, but could be even lighter thanks to the utilization of carbon fiber. The current MX-5 uses high-strength steel and aluminum, and Mazda doesn't use carbon fiber in any of its cars. Carbon fiber is expensive to incorporate into road-going vehicles, and so Yamamoto notes that Mazda has been hard at work making it more affordable. A lighter car could result in a smaller engine, Yamamoto said. In the US, the MX-5 comes with a 2.0-liter four-cylinder engine that makes 155 horsepower, while the Japanese and European version comes with a 1.5-liter, 130-hp engine. A smaller engine would make the sports car even lighter. It's unknown at this time if the automaker is collaborating with another automaker or a supplier to make produce carbon fiber, or if it'll make it in-house. There's no word on how much carbon fiber the next MX-5 will wear or how it will affect the sports car's price. Autocar reports that the next MX-5 won't arrive anytime before 2021, which could make the ND MX-5's lifespan an unusually short five years long. With cars getting heavier, it's nice to hear that Mazda is working on finding a way to make its lightweight sports car even lighter.

Mazda revamping dealers with 'Retail Evolution'

Mazda introduced its Retail Revolution dealership design language 12 years ago, which focused on open-plan spaces, multimedia areas, and allowing customers to interact with the brand before needing to interact with a salesperson. Two years ago the carmaker started work on the next step in its dealership design, and the new language, called Retail Evolution, was unveiled at Mazda of Everett in Seattle, Washington. Aiming to make the Mazda brand feel more premium and increase dealer profits, it goes even further on the open-plan to create "a new level of business transparency." It's all done with a lot of black, white, raw wood, metal finishes, and a lot of glass. Mazda Lounges will offer free wi-fi, and digital displays will replace static photographs. So as not to hurt showrooms still recouping their investment in Retail Revolution, Mazda will work with dealers to figure out how best to update facilities, and the Retail Evolution has three tiers that can be adapted to particular locations. The press release is below, a couple of renderings are above. MAZDA ANNOUNCES ALL-NEW RETAIL EVOLUTION DEALERSHIP DESIGN Mazda of Everett Showcases First Ground-Up Retail Evolution Design IRVINE, Calif. (August 27, 2015) – Mazda North American Operations (MNAO) today announced its all-new dealership design, dubbed "Retail Evolution", featuring an open concept floorplan that offers a new level of business transparency, and a look and feel enhanced through the use of natural materials that results in an even more upscale decor than the company's current popular Retail Revolution design. The first Retail Evolution dealership built from the ground up to this exacting standard will be Mazda of Everett in Seattle, Wash., opening today. "Thanks to our KODO design philosophy and suite of SKYACTIV technologies, our vehicle lineup has never been stronger. We are now able to take that groundbreaking design language and translate it into our dealership experience," said Jim O'Sullivan, president & CEO, MNAO. "Retail Evolution embodies the spirit and direction of the Mazda brand, while offering an upscale experience our customers expect and deserve." Clad in premium black, clean white, and featuring new chrome Mazda signage, the new Retail Evolution Mazda dealerships will provide dealers with strong curb appeal. New materials throughout the building give dealers an upscale look and feel with warm raw-material tones of wood and metal in the showroom.

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.
