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.

How Mazda got Skyactiv-X to work is incredible

"Take everything you know about engines and turn it around," Mazda North America Vehicle Development Engineer Dave Coleman says, patiently and with a look of benevolent pity, as he's quizzed about the particulars of the company's new engine. The Skyactiv-X engine is enigmatic — and deceptively simple in operation. And the bottom line for American consumers is that they'll be able to buy a car (or crossover; we don't know yet what vehicle will first get it) by late 2019 that provides diesel-like fuel economy but runs on regular old gasoline. In between diesel and spark ignition, but it's neither To truly understand it, you have to dive into the contradictions. Take that regular old gasoline: Contrary to common sense, the lower the octane, the better it works. In the lab, the Skyactiv-X engine loves 80 octane. The lowest Americans get is 87, so the engine is tuned for that octane. Go higher and you lose some low-end torque. Coleman was right. It's hard to wrap your head around an engine that thrives just at the point when most gas engines would aggressively self-destruct. It uses a supercharger to pump additional air — but not additional fuel. It uses spark plugs to start a combustion cycle that normally doesn't need a spark. And, quixotically, it's not displacing Mazda's own American-market diesel engine, currently languishing in a seemingly endless hell of regulatory approval. More bizarre: Mazda is a tiny automaker facing real existential headwinds, and gasoline compression ignition is a massive challenge. GM and Hyundai announced compression ignition, or HCCI, projects (full name, homogeneous charge compression ignition) to great fanfare, but they never amounted to a production hill of beans, crippled by reliability issues or horrible vibrations. Worse, they only worked at an unusably narrow range — low RPMs and low loads. HCCI research improved direct-injection gas and diesel engine technologies for these companies, but HCCI itself remains untamed. The benefits of lean combustion Why even try to tame HCCI? The answer is much better fuel economy and lower emissions. Less burned carbon-based fuel, less carbon dioxide released. That's simple. But there are some thermodynamic reasons for the lean combustion you can achieve with compression ignition that are worth explaining. The ideal amount of fuel for a conventional engine to burn is about a 14:1 air-to-fuel ratio. That lets every molecule burn nicely, in theory.

Illinois’ pro-union stance kills bid for Toyota-Mazda plant, report says

Mazda and Toyota are fielding bids from states eager to land its new prize: an all-new $1.6 billion U.S. plant where the Japanese automakers would jointly build electric vehicles and employ around 4,000 workers. Now we can apparently scratch Illinois off the list of contenders. According to Automotive News, the Land of Lincoln has been disqualified due to a lack of shovel-ready sites and the state's lack of a right-to-work law curtailing union membership. Mark Peterson, the president and CEO of economic development agency Intersect Illinois, told the publication he's been informed Illinois is not among the three or four finalists for the facility. It's believed those finalists are all in the South. Peterson said that "many national site consultants charged with making recommendations for corporate relocations and expansions will not even consider a state that is not a right-to-work state. In this case, the three states I am told are still in the running are all right-to-work states." The Midwest may be the ancestral home of U.S. automotive manufacturing, but the South has made major inroads in recent decades, with the likes of Honda, Mercedes-Benz, Nissan and Toyota all opening plants there, among others, thanks to lucrative tax incentives and the absence of labor unions. Recent years have also seen so-called right-to-work laws, which prohibit union dues and membership as a condition of employment in organized workplaces, spread to traditional labor strongholds such as Michigan and Wisconsin. The new joint venture plant, which would start operating in 2021, would be capable of producing 300,000 vehicles a year, with production divided between the two automakers. Mazda and Toyota would also take small stakes in one another as part of the deal. It's expected that at least 15 states have submitted proposals to attract the plant. Expect the Illinois news to trigger a new round of debate over the role of organized labor in the modern economy.Related Video: Image Credit: Reuters Green Plants/Manufacturing Mazda Toyota
