Mazda's mission for the 2017 CX-5: Smooth out the NVH

NVH: the dreaded noise, vibration, and harshness. According to current Mazda CX-5 owners, as well as those who decided against becoming owners, NVH was its biggest area of need. Traveling in the CX-5 was just too loud, so Mazda's engineers made sure that the redesigned, second-generation model would offer its occupants a more serene environment in keeping with quieter competitors. To reduce wind noise, more aerodynamic parts were strategically placed about the exterior, while extra efforts were made to reduce low-frequency noises on coarse surfaces. According to Mazda engineer Dave Coleman, the new CX-5 is nearly as quiet as its platform-mate, the 2016 CX-9. Actually, to be very accurate, all Mazdas apart from the CX-3 and 2 (aka Toyota iA) now share that platform. Another reason compact SUV buyers opted to skip the CX-5 was its comparatively firm ride. So, while the CX-5 remains "head and shoulders above the segment for handling," according to Coleman, the ride was improved. One of the primary ways of achieving that was the adoption of rigid steering mounts, which allowed for the suspension to be less stiff without a loss in handling precision.

Under the hood, every CX-5 now comes standard with the 2.5-liter Skyactiv-G four-cylinder, with output figures to be announced at a later date. The 2.0-liter, previously standard on the Sport trim, has been exiled to other markets. However, finally making its appearance on these shores is Mazda's 2.2-liter Skyactiv-D diesel engine. Although Mazda did its darndest to make it certifiable in the United States without a urea injection system, it was ultimately unable to do so without resorting to an ultra-sluggish throttle response that engineers deemed was anathema to what was expected of a Mazda. Therefore, the diesel-powered CX-5 will indeed have a DEF tank that will need to be periodically topped off to not run afoul of emissions regulations. Otherwise, the 2017 CX-5 is very much an evolution of the SUV it replaces. Customers thought its size was just right, so its passenger and cargo area remain in the same ballpark.

Weekly Recap: GM plans massive new paint shop at Chevy Corvette factory

General Motors is laying out some serious green to maintain the Chevy Corvette's expansive color palette. The automaker is breaking ground on a new paint shop this summer that's part of a $439-million investment to upgrade the 34-year-old Bowling Green, KY, factory that builds the Stingray. The massive new structure will total 450,000 square feet, nearly half the size of the current 1-million square-foot facility. Construction is expected to take two years and won't impact Corvette production. The upgrades include new robots that save paint and create a better finish, longer, more efficient ovens to bake in the finish, and LED lighting. There's also a dry scrubbing booth technology with a limestone handling system that eliminates waste. GM has invested $135 million in the factory in last four years for the changeover to build the C7 and to relocate its Performance Build Center to Bowling Green. The improvements continue to modernize the Kentucky factory, which has become a tourist attraction in its own right, as more than 56,000 enthusiasts visited it last year. The upgrades are part of a $5.4-billion investment GM confirmed in April that will remake its US footprint in the next three years. The Bowling Green expansion underscores GM's continued commitment to the Corvette, which sold nearly 38,000 copies around the world last year, an eight-year high. "With this major technology investment, we can continue to exceed the expectations of sports car buyers for years to come," North American manufacturing manager Arvin Jones said in a statement. OTHER NEWS & NOTES Takata recall hits 34 million vehicles The National Highway Traffic Safety Administration expanded the Takata airbag recall to an almost unthinkable 34 million vehicles on Tuesday. The recall is part of an agreement reached by the two sides where Takata admitted some of its airbag inflators have a defect, and the deal compels the company to comply with all future regulatory actions and investigations. Takata's airbag inflators were produced with "a propellant that can degrade over time" and lead to ruptures, NHTSA said. Six deaths have been attributed to the flaw worldwide. Investigations conducted by Takata, automakers, and others have not determined the exact cause of the inflator problem, but NHTSA said moisture appears to alter the propellant's chemical structure. It then ignites too rapidly, creates too much pressure that ruptures the inflator, and blasts shards of metal at passengers.

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.
