Autoblog readers meet the 2016 Mazda MX-5 Miata [w/video]

Mazda dropped off a 2016 MX-5 Miata at our office this week with only two stipulations: don't break it, and don't talk about driving impressions until 3:01 AM Eastern on Monday, June 1. Easy enough. But rather than hold our notes until the embargo lifts, we decided to do something different. By now, you've no doubt read all there is to know about the 2016 Miata, including our review of the Japanese-spec car with the 1.5-liter engine that isn't coming to North America. You know it's smaller than the outgoing NC model. And you know that, at 2,332 pounds, it's nearly as light as the original. But what you, and we, didn't know, is what Miata owners think about the 2016 model. The MX-5 group is incredibly enthusiastic, and they love their cars. Hell, they love each other's cars. So we gave them an opportunity to not only get together, but to get an up-close, informal look at the ND Miata outside of an auto show, several months before it officially goes on sale. Here's what we did. Cars And Coneys Anyone who's familiar with the Woodward Dream Cruise in metro Detroit has no doubt heard of Athens Coney Island in Royal Oak, MI. It's an iconic place, known for its top-notch coney dogs, quick service, and the fact that, on pretty much any warm-weather weekend, you can find cool cars in the parking lot. We called the folks at Athens, told them about our Miata meet-up, and they were immediately on board with coneys, soda, and coffee for our gathering. We first published our meet-up info late last week, and sent the details out on our social media channels, as well. But without any formal RSVP system, we had no idea how many people would show up. And since Mother Nature decided to provide us with gray skies and chilly temperatures, we figured a lot of would-be attendees opted to bail at the last minute. Needless to say, we were surprised to see several Miatas already lined up in the Athens parking lot when we arrived with the ND at 4:40 PM, 20 minutes before the listed 5:00 start time. No one kept a formal count, but our best guess is that something like 50 or 60 cars showed up over the course of three hours. Some folks stayed the whole time, some people only stopped by for a quick cup of coffee. A couple people drove long distances to attend – a few Miatas hailing from southern Ohio, and many from western Michigan. We had a huge mix of cars, too.

Mazda's Hofu plant builds its ten-millionth car

Ten million is a lot no matter which way you cut it, and no matter what you're talking about: Ten million dollars, ten million miles, ten million people... certainly ten million cars. And that's the milestone that Mazda's Hofu plant in Yamaguchi prefecture of Japan has just achieved.
The Hofu facility has been in operation since 1982, and was supplemented with a second plant on the same site ten years later. Hofu reached a million units built in 1986 and five million in 2002. But with production now at 482,100 units per year, it took less than twelve years to double that previous milestone.
The magic ten-millionth car was a new Mazda6 (known locally as the Atenza), which is built at Hofu Plant No. 2, while Hofu Plant No. 1 gears up for the new Mazda3 (aka Axela). Scroll down below for a related press release.

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.
