2020 Mazda6 Signature Driveway Test | A luxury car interior with a non-luxury price

The 2020 Mazda6 Signature is pure luxury on the inside. If one were to remove the Mazda badges and replace them with Audi’s four rings, or LexusÂ’ stylized L, customers may not even bat an eye. Alas, that is the point of MazdaÂ’s range-topping Signature trim. Mazda fancies itself a “premium” car brand at this point, and the Mazda6Â’s cabin does an excellent job of selling that theme. A luxury interior starts with excellent and original design, and then itÂ’s finished with quality materials. Anybody can throw leather, suede and wood around, but if the design itself isnÂ’t moving, the fancy materials look tacked on. Mazda has managed to ace both the design and material quality sections of its test with the Mazda6 Signature. ThereÂ’s beauty in simplicity, and the Mazda6Â’s interior exemplifies that. A wide, sweeping dashboard dominates the view from the driverÂ’s seat. An endless swath of soft-touch UltraSuede is front and center, splitting the climate controls from the vents and infotainment screen above it. Mazda says itÂ’s “adorned with a subtle gold tint,” and itÂ’s made in a similar fashion as ornate kimonos. I found myself staring at the stitching running the full length of the dashboard. ItÂ’s topped by a silver strip that extends from one side of the cabin to the other into the side air vents. Interestingly, the side air vents extend beyond the rest of the dash into the door, so they look like silver metal wings sticking out with the doors open. Above the silver strip is something Mazda calls “Sen Wood.” It looks and feels like real wood, because it is — Mazda says Sen wood is used in taiko drums and Japanese furniture.   And then thereÂ’s the lovely continued presence of physical buttons for vital controls. All of the climate control options are integrated into a classy strip just below the suede in the center of the dash. The buttons themselves are high quality, easy to find and satisfying to use in their action. Same goes for the climate control temperature knobs. They turn with precision and give a clear indication of each degree of change. The ribbed faux metal (it's extremely convincing as real metal) surround on the dials makes it feel like youÂ’re changing the climate control on a car that costs twice as much as this Mazda does. Even some luxury cars donÂ’t offer the same level of tactility and satisfaction in their controls.

Mazda working on lithium-ion batteries to replace lead-acid starter batteries

In the quest for ever better fuel economy, car companies are looking for every single advantage possible, no matter how small. This is evident in everything from active grille shutters to the 48-volt mild-hybrid electric assist systems like that in the new Ram 1500. For Mazda, the latest target for potential efficiency gains is the lowly 12-volt starter battery. The company announced that it is partnering with two other companies, ELIIY Power and Ube Industries, to develop a lithium-ion starter battery that would be used on mainstream models in place of conventional lead-acid units. Mazda plans to have them ready for use by 2021. The advantage here would be that 12-volt lithium-ion batteries would be much smaller and lighter than the lead-acid ones they replace. And lighter cars don't need as much fuel to move around. Plus, as an added benefit, making cars lighter also often makes them faster and better handling. This is why companies such as Lotus and Porsche have offered optional lithium-ion 12-volt batteries for some lightweight sports cars. A potential downside to the use of these batteries is increased cost. Lead-acid batteries from your local parts store will run you between $100 to $150. AGM batteries could be between $200 and $300. As for lithium-ion batteries, Lotus introduced the option on the Evora 400 in 2016, and the option cost $1,690. Odds are that a company such as Mazda won't be absorbing all those costs, meaning that the cost of these future Mazdas could increase with a change from lead-acid to lithium ion. Related Video:

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.
