Mazda hands over first factory-restored Miata

In August 2017, Mazda announced that it will be offering factory quality restoration work for the original, NA body Mazda MX-5 Miata introduced in 1989. The program also included parts support, as Mazda wants to underline how much the original Miata still means to it. The program was launched with exemplary work carried out on a Miata owned by Mazda, but the first customer car has now been finished. The first car was picked from 600 applications sent to Mazda. Out of all these cars needing factory certified work, the 1992 British Racing Green V-Special owned by retired tomato farmer Keiji Nishimoto was chosen to be the first. The Eunos-badged limited-edition car was bought new by Nishimoto, and he told Mazda the car had been instrumental in creating some wonderful road-trip memories. The V-Special edition came in a British roadster-style color combination: "Neo" green over tan leather, complete with a retro-style Nardi wood wheel. The car also has a front strut bar and a limited-slip differential. Nishimoto had already been planning to get his car restored, but getting it done by Mazda during the summer was even better. The car was finished in August, and it was officially handed over to its owner in September. To have owned and enjoyed a car for a quarter-century and getting a chance to experience it in as-new condition again must be a fantastic experience. Nishimoto says the car is now good for another 25 years of driving. For the time being, the TUV Rheinland certified restoration program is only available for Japanese customers. But since a large percentage of first-generation Miatas are still on the road, and a large percentage of those will need bodywork done in all the usual places, we would happily see Mazda reach out to European and American customers 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 returns to rotary with RX-Vision Concept, crowd goes wild

Rotary! Forget everything for a second. Ignore the sleek styling, formed-by-wind sheetmetal, outrageously rear-drive proportions, and general ridiculousness of the sideview mirrors. And please be so kind as to ignore the poorly lit photos here – Mazda has a thing for drama. Concentrate instead on one fantastic phrase from the concept car press release: "next-generation Skyactiv-R rotary engine." The crowd here in Tokyo was downright frothing to get a look at the new concept car – hoping to catch a glimpse of the first evolutionary stage for a RX-9 sports car. The critical factor in that effort is of course the rotary engine. Mazda says that, while production of the powerplant is "on hold," the company has "never stopped research and development towards the rotary engine." The fact that the company has named the new engine gives us great hope that it exists in reality, and will be available for sale at some future date. The devil is in the details though, and there are precious few available at the Mazda stand. Other than a brief history lesson about Mazda's racing heritage, and fuzzy-vision talk about the future, we only have expectations to feed on. Oh, there's also a tiny press release, below.

The rotary engine is a symbol of the company's "never-stop-challenging" spirit. RX-VISION represents a vision of the future that Mazda hopes to one day make into reality; a front-engine, rear-wheel drive sports car with exquisite, KODO design-based proportions only Mazda could envision, and powered by the next-generation SKYACTIV-R rotary engine. Rotary engines feature a unique construction, generating power through the rotational motion of a triangular rotor. Overcoming numerous technical difficulties, Mazda succeeded in commercializing the rotary engine, fitting it in the Cosmo Sport (known as Mazda 110S overseas) in 1967. As the only automaker to mass-produce the rotary engine, Mazda continued efforts to improve power output, fuel economy and durability, and in 1991 took overall victory at 24 Hours of Le Mans with a rotary engine-powered race car. Over the years, the rotary engine has come to symbolize Mazda's creativity and tireless endeavor in the face of difficult challenges. While mass production is currently on hold, Mazda has never stopped research and development efforts towards the rotary engine.
