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.

2014 Mazda3

Almost by definition, affordable compact cars aren't supposed to be fun. Sure, hot hatches get our blood pumping, but not long ago, the terms "compact car" and "economy car" could safely be used interchangeably. A key exception for the last decade has been the Mazda3, a car that has consistently delivered more dynamic thrills and tactile feedback than its contemporaries. Competitors have picked up their game significantly in recent years, however, leaving the Mazda3 wanting in several areas, including overall refinement, in-car technology and cabin appointments, so Mazda went back to the drawing board to create this all-new third-gen model for 2014.
Including this redesigned 2014 model, Mazda's recent crop of new products have targeted North America's hottest non-truck segments - compact car, midsize sedan and compact crossover/SUV. Yet it might be fair to call this launch the most important of them all, as the 3 remains the Japanese marque's best-selling vehicle. While America's pool of compact hatchbacks isn't exactly deep, the 2014 Mazda3 still has a challenging road ahead of it competing against two-box compacts that include the popular Ford Focus and recent additions like the all-new Kia Forte and the still-new Hyundai Elantra GT.

Mazda3 celebrates 10 happy years

Mazda is on the cusp of unveiling an all-new Mazda3, but the compact will mark an important milestone before that happens. The very first Mazda3 rolled off of the assembly line on June 25, 2003. A decade later, the little car has snagged some 136 awards. The first generation sold 2.2 million units over the span of six years, and the second has smiled its way into the hearts of 1.4 million buyers since 2009. Mazda notes the machine even took the honor of being the top-selling passenger car in Australia in 2011 and 2012.
So, what will the future bring? The Japanese automaker is keeping the details to itself for the moment. From the spy photos we've seen, it looks as if the new design will fall under the company's new Kodo design philosophy. That same language brought us the perilously sexy Mazda6, and the new Mazda3 should be no less attractive. You can check out those photos here.
