Mazda hits Vegas with a pair of Sixes

Despite the fact that the annual SEMA show is more of an exercise in what "could be" than what "will be," it gives automakers the chance to stretch the legs of some of its most important models. Take the 2014 Mazda6, for example - it's hardly new, having gone on sale early this year - but this year's SEMA expo marks the first time Mazda has been able to show off the customization possibilities for its sleek midsize sedan. To that end, the Japanese automaker has arrived in Las Vegas with two very different takes on its sexy Six.
First up is the Mazda6 Club Sport you see above, wearing a "motorsports-inspired" gray, black and red accent-color scheme that, as Mazda says, is "represented in not-so-subtle angular lines reminiscent of a car speeding past your line of sight." The whole car is done up in a base color of Composite Grey, and uses a Brilliant Black roof to match the similarly colored front, side and rear diffusers, as well as the rear spoiler. Mazda has fitted the Club Sport with Rays 57 Motorsport G07FXX 20-inch wheels, wrapped in Yokohama 245/35R20 tires. Powering the CS is Mazda's 2.2-liter Skyactiv-D diesel four-cylinder engine (that we'll get in the standard Six early next year), and other changes include an H&R spring kit, larger Brembo brakes and a Racing Beat exhaust.
And then there's the Ceramic 6 Concept, pictured right. The name comes from the car's Ceramic White paint, though we don't really get the Taupe Silver accent stripes. Mazda says they're meant to mimic "the linear frequency patterns found on the likes of couture dresses and flowing fabrics," but it just looks a bit overwrought to us. The Mazda6 already has so many clean lines, why add more?

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.

The Mazda MX-5 Miata RF's trick roof will cost you at least $2,555 extra

Now that loyal customers have been given the opportunity to preorder the Mazda MX-5 Miata RF Launch Edition, Mazda has finally announced pricing for the regular 2017 MX-5 RF lineup. The vehicle, with its gorgeous power retractable hardtop, will come in two trims – the MX-5 RF Club and Grand Touring when the vehicle goes on sale early next year. The MX-5 RF Club with the manual transmission is priced at $32,390, including $835 destination, which represents an additional $2,955 over a six-speed manual MX-5 Club with a soft top. An automatic is a $730 option for both RF and soft top Club models. The range-topping MX-5 RF Grand Touring trim will start at $33,455 with a six-speed manual transmission, which is $1,170 less than the Launch Edition's price tag of $34,685 and $2,555 more than a soft-top model. Opting for the automatic transmission on the Grand Touring trim bumps the price tag up to $34,660. The MX-5 RF models are similarly equipped to the soft-top models. The Club models benefit from cloth seats with red stitching, a limited-slip differential (when equipped with a manual transmission), suspension from Bilstein, and an optional Brembo brake and BBS wheel package for an extra $3,400. The more luxurious Grand Touring models get adaptive headlights, heated leather seats, and lane departure warning. The MX-5 RF models, just like the regular soft-top models, don't have many options. Hands-free keyless entry is a $130 option, while premium paint options, which includes Machine Gray Metallic (the same color on the Launch Edition) and Soul Red Metallic both cost $300. Crystal White Pearl Mica is only available on Grand Touring models and will cost an additional $200. Unlike the Launch Edition that was limited to only 1,000 units, there's no production limit on the regular MX-5 RF. Mazda will being delivering the MX-5 RF Launch Edition in February of 2017, with the standard MX-5 RF models following shortly after.
