Mazda de Mexico celebrates 100,000th car built

Automakers and their factories celebrate production milestones all the time. Some are interesting enough to report on and some aren't, but what makes this one stand out is that the plant opened less than a year ago. Just 11 months since production began, Mazda de Mexico Vehicle Operation has put together its 100,000th vehicle – in this case a Mazda2 hatchback headed for Europe. MMVO is one of three plants assembling the company's smallest model, also known as the Demio in Japan, where it is also produced, with additional assembly taking place in Thailand under a joint venture with Ford. The Mexican location also handles assembly of the Mazda3 for the Americas and for Europe. Mazda has announced that it is expanding production at MMVO by 150 percent of this year's capacity to 250,000 units per year by March 2016 as it takes on contract manufacturing for Toyota as well.

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.

Mazda concept probably previews the next Mazda3 at the Tokyo show

This year's Tokyo Motor Show is shaping up to be an interesting one, with a Nismo Leaf, Mitsubishi e-Evolution concept, and a pair of interesting Toyota concepts already lined up. Now Mazda is joining with its own big reveal of two concepts. One is a design concept that will give us an idea of where the company is heading, and another is all but guaranteed to be our first look at the new Mazda3. There are a few reasons we say that one of these concepts has to be the next Mazda3. One is the fact that Mazda says it's a concept planned for production. The company also describes it as "a compact hatchback that fuses next-generation technology and design," and it uses the new Skyactiv-X spark-controlled compression ignition engine and "Skyactiv-Vehicle Architecture." Plus, just looking at the teasers, the design is a clear evolution of the current Mazda3 hatchback. It looks as though the hood and roofline curve a bit more, and some of the sharp creases of the current car have been smoothed out. The other concept Mazda is bringing to the Tokyo Motor Show seems to be just that, a concept. Mazda says it's just a design concept meant to exhibit how other Mazdas will look. Apparently it's a continuation of the company's current "Kodo" design language. Based on the teaser image, the car appears to be a sedan and consists mainly of clean, elegant curves, with hardly a crease anywhere except the edge of the trunk. The elegant lines are reminiscent of the RX-Vision concept, just with a couple extra doors and a different color. Mazda will have a couple of other new vehicles on display in Tokyo as well. The company will show the Japan-only CX-8 three-row crossover and a special-edition Roadster (Miata) Red Top edition. We presume it's a Miata with a red soft top. Stay tuned for more details from the full reveal. Related Video:
