Mazda Miata speedster and spyder concepts set for SEMA

Mazda will show speedster and spyder concepts based on the 2016 MX-5 Miata next week at SEMA in Las Vegas. The speedster is at the top of the teaser, and the spyder is the bottom half. The speedster goes with an extreme lightweight design. It has only a small wind deflector in place of the windshield and a blue ether topcoat. The spyder is a vintage roadster rendered into a modern form with a handcrafted leather interior and mercury silver paint job. Both are lighter than the production version and will be sure to get the hearts of Mazda fanatics and roadster enthusiasts alike racing at the possibilities. We doubt either will actually see production, like so many Miata-based concepts of the recent past. But that won't stop us from dreaming all the same. MAZDA TO SHOWCASE LIGHTWEIGHT PERFORMANCE AT SEMA WITH TWO MX-5 MIATA CONCEPTS - MX-5 Spyder and Speedster Concepts Bring Vintage Cues into Modern Designs - IRVINE, Calif., Oct. 29, 2015 -- The Mazda MX-5 Miata has been an exercise in honing the concept of a lightweight sports car for more than 26 years, created solely for driving exhilaration. But for the 2015 SEMA Show at the Las Vegas Convention Center, Mazda designers wanted to see what they could do if that idea was taken to the extreme. What they created were two vastly different takes on the fourth-generation MX-5: The 2016 MX-5 Spyder Concept and 2016 MX-5 Speedster Concept. MX-5 Spyder captures the character of a vintage roadster and translates it into a modern-day design, including bespoke leather interior details that were painstakingly crafted, and featuring a new Mercury Silver concept paint color. MX-5 Speedster is a study in the extremes of lightweight, purpose-built performance, paying homage to minimalist roadsters of the 1950s. The Blue Ether-painted MX-5 Speedster is uncompromised in its approach to wind-in-the-hair driving, going so far as to eschew a traditional windshield for a lighter deflector. Both cars are significantly lighter than the 2,332-lbs. MX-5 roadster that customers can purchase at dealers and come with a host of conceptual and aftermarket pieces and fabrication from partners including Racing Beat, Haartz Corporation, ASC – American Sunroof Corporation, Makin Industries/RAYS Wheels, KW Suspensions, Delta Seat, H&R Springs, Lusch, AC&A Manufacturing, Franks Fab Shop, Long Road Racing and SIM Specialty Interior Manufacturing.

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 builds 4-millionth Mazda3

To say that the Mazda3 is a vital product for Mazda would be one heck of an understatement. In fact, the model line accounts for about 30 percent of the manufacturer's sales. Fortunately for Mazda, they're selling well.
These days, the Japanese automaker is building the Mazda3 (known domestically as the Axela) in Japan, China, Thailand and, as of last month, in Mexico. The company's expanded global production capacity has helped Mazda reach four million units of the Mazda3 sold around the world since the first model was introduced over ten and a half years ago.
Over the course of that decade since its introduction in June 2003, Mazda has gone through three generations of Mazda3, the newest model benefiting from the company's Skyactiv technology and even encompassing a hybrid model in the Japanese Domestic Market.
