Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

Mazda mulling furniture, designer goods in bid to command higher prices

Brands like Porsche and Ferrari make a mint every year by selling branded lifestyle goods like shoes, hats and even wilder items. Bugatti takes things to the extremes with things like its $84,000 belt buckle. These products not only make their respective companies some extra money, but they reaffirm their high-end design aspirations to wealthy buyers. However, the next firm possibly dipping its toe into this upscale pool is a bit more mass-market - Mazda.
That's right. The Japanese automaker best known among enthusiasts for its segment-defining Miata and rotary engines is considering its own line of luxury goods in the coming years called Mazda Design. The project is the brainchild of styling boss Ikuo Maeda, and according to Automotive News, he has backing from company CEO Masamichi Kogai. Although the green light isn't quite on yet, Maeda is already brainstorming. "Not only furniture, but I'd like to build a Mazda Design brand. That's my dream," he said to Automotive News.
The possible project is just one aspect of Mazda's move to become a near-premium brand. According to Automotive News, it wants to see higher transaction prices partially by offering more stylish design than its rivals. Launching a line of luxury goods is meant to communicate this new focus to customers.

2014 Mazda3 configurator zoom-zooms to life

The 2014 Mazda3 is probably going to be on a lot of shopping lists, thanks to its striking good looks, clean interior treatment, fuel economy and driving character. If it happens to be on your personal list of new cars to test, you'll be happy to see that the configurator for Mazda's newest product has officially gone online.
In terms of build-your-own web items, configuring a 3 isn't much of a departure from the rest of the Mazda range. Most of the work comes from choosing one of the three trim levels - Sport, Touring and Grand Touring - and selecting either the 155-horsepower, 2.0-liter, Skyactiv four-cylinder or its larger sibling, the 184-horsepower, 2.5-liter, Skyactiv four. From there, a simple range of color and interior finishes are available, before a slim list of packages, options and accessories. Really, Mazda's made it easy to get through this build process.
Click on over to the configurator and take a look at the options, colors and prices for Mazda's newest five-door hatchback.
