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.

Goodbye Zoom-Zoom, Driving Matters is Mazda's new slogan [w/video]

Timed with the launch of the 2016 MX-5 Miata, Mazda is now changing gears with its advertising strategy in the US by launching a whole new slogan. The Japanese brand's latest marketing motto takes a much more direct approach than Zoom-Zoom by simply saying Driving Matters. The two-word phrase is meant to make customers believe that a good time behind the wheel can improve their lives. Driving Matters is also supposed to say something about how Mazda engineers vehicles. "Whether it's for safety purposes or for maintaining our 'fun to drive' nature, it all comes down to the fact that driving matters to our customers and it matters to us." Russell Wager, vice president of marketing at Mazda North American Operations, said in the announcement of the new campaign. However, Zoom-Zoom isn't entirely dead, and the words still appear in small print in some of these spots. According to Wager in an interview with Automotive News, the old slogan isn't necessarily understandable to some focus groups. "I'll ask them to explain to me what 'Zoom Zoom' means, and I'll get 6 or 7 different answers. That's what Driving Matters is supposed to address. It's supposed to solidify what 'Zoom Zoom' means to people," he said. So far, the company has released several examples of the campaign to highlight the Miata and Mazda6. At the same time, Mazda is launching a new commercial (embedded below) called A Driver's Life that showcases many of its models but puts a big emphasis on the MX-5.

Mazda Launches All-New Advertising Campaign, "Driving Matters" - New Campaign Communicates How the Joy of Driving Can Enhance Your Life - IRVINE, Calif. (May 21, 2015) –The Oxford Dictionary defines "driving" as, "operating and controlling the direction and speed of a motor vehicle." Mazda believes that driving is more than a definition. Driving is an experience that can enhance your life. To better illustrate how every Mazda vehicle embodies why "Driving Matters," today Mazda North American Operations (MNAO) is rolling out a new advertising campaign. Driving Matters is an evolution of the Game Changers campaign. With Game Changers, Mazda succeeded in increasing consumer awareness of the functional attributes of our vehicles. Driving Matters will extend the message by creating an emotional connection to the brand.

Mazda6 Skyactiv-D Racecar ready to bring diesel to Grand-Am

It may not be quite as radical as some of the company's past rotary racers, but the new Mazda6 Skyactiv-D racecar does have a notable powertrain underhood: the automaker's brand-new clean diesel four-cylinder engine.
Three of these new diesel-powered Mazda6 racers will take to the track in the Grand-Am GX class of the upcoming 2013 Rolex 24 at Daytona on January 26, with five drivers on each team. The car you see above, number 70, is sponsored by Mazda's longtime motorsports partner, SpeedSource.
