Mazda2 sedan debuting in Thailand this month?

Mazda is reportedly set to introduce a Mazda2 with a four-door sedan body. Unlike the upcoming CX-3, which is debuting at the upcoming Los Angeles Auto Show and is almost certain to be sold in North America, this other version's chance here are a bit more mysterious.
According to The Bangkok Post, the Mazda2 sedan will make its word debut at the Thailand International Motor Expo on November 28, and the traditional five-door hatch will be there as well. Both body styles will be built in Thailand with diesel engines and will be the first vehicles to adhere to the country's eco-car rules for oil-burners with a SkyActiv 1.5-liter diesel that will make 105 horsepower.
At this time, there's no indication whether the new sedan might also be sold in the US, but we're not holding our breath - remember, the previous Mazda2 sedan never made it Stateside, either.

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.

Takashi Yamanouchi to retire as Mazda chairman

Takashi Yamanouchi has been with Mazda for a long time. He signed on with the Japanese automaker in April 1967 - one month after graduating from Keio University - and rose through the ranks over the years. By 1996 he was named to the company's board of directors. In 2008 he was named president and CEO, an office he held until 2013, after which he handed over the day-to-day reins to Masamichi Kogai and took up the seat at the head of the board room to serve as the company's chairman. But now, after 47 years working for Mazda, Yamanouchi-san is retiring at the age of 69.
During his tenure as CEO and then as chairman, Yamanouchi was credited with growing Mazda's business despite unfavorable fluctuations in exchange rates, opening the company's first plant in Mexico, and spearheading the development of Mazda's Skyactiv technologies and Kodo design language.
In his place, current vice chairman Seita Kanai will take over as chairman. The changing of the guard will take place after the annual shareholders' meeting on June 24.
