Mazda keeping non-hybrid, non-electric Skyactiv strategy

Mazda still thinks that it can buck the trend of adding those fancy batteries and electric motors to its cars. At least for a little while longer. Hopefully. Speaking to Auto Express recently, Mazda's European boss, Jeff Guyton, said that he expects his company's cars to be able to get a lot more efficient without resorting to any of that fancy electrification stuff. "I think there's at least 20-30 percent better fuel economy by the end of the decade," he said. He said that he expected to get to Europe's low target of 95 grams of CO2 per kilometer, "without any significant deployment of electrical drive." This part is all in line with Mazda's long-term Skyactiv strategy, as laid out back in 2011 and first mentioned publicly in 2010. Remember, this is the company that once proudly proclaimed, "Not Electric. Not Hybrid. Not A Drag To Drive." As explained back in 2011, Mazda hopes to wait until other automakers have done all of the heavy lifting on developing plug-in and hybrid tech so that when Mazda enters the market, things will be cheaper. Of course, Mazda has been quietly testing all-electric vehicles and Guyton said that there may be an Mazda EV at some point. "We are interested in electric technology and it will be in the distant future when it will be quite important," he told AE. "But we think it will take some time to be commercially attractive without tax payer-funded incentives." How much of a delay? Well, there is a gas-electric Mazda 3 hybrid available in Japan that uses some powertrain parts from the Toyota Prius, and we all know that the Prius has been around for ages. Maybe in 2025, Mazda will come out with a Leaf-based Mazda 2. Related Video: Green Mazda Fuel Efficiency Electric Hybrid skyactiv mazda skyactiv

Mazda Skyactiv-X Review | The revolution begins with a squeeze-bang

The matte black Skyactiv-X prototype looks like a rough Mazda3, perhaps reconstructed after a bad wreck by an over-enthusiastic owner of a spot welder and lots of gaffers' tape. Ribbed ducts poke out of the dash sending two breaths of conditioned air to no one in particular. Even its revolutionary engine, the thing we're here to experience, is entombed in a massive, nondescript cover to mask its unseemly noises. It's a wild, strange way to meet a very unconventional vehicle that promises diesel-like fuel economy, a wide torque band, and an exotic method for burning less gas than ever before. It takes a few hours for Mazda's engineers to explain the fundamental principles of operation. For more detail, read our Skyactiv-X Spark Controlled Compression Ignition explainer, but here's a very brief overview. Skyactiv-X marries some traditional gasoline engine characteristics with a novel form of compression ignition called SPCCI. The key for Skyactiv-X is to use very high compression in the cylinder and an extremely lean fuel-air mixture. Squeezed right to the cusp of getting hot enough to blow up all on its own (which is very hard to predict), a squirt of extra gas and a spark interject to cross that compression-ignition threshold in a controlled and predictable manner. See the animation below: That takes a few essential components to get just right. One is a massive amount of computer processing power and some pressure sensors in the individual cylinders, because the ambient conditions change how and when these things happen. Skyactiv-X uses a clutched supercharger to pump in additional air when needed to nail the mixture precisely, and high-pressure injectors to get the low ratios of fuel to disperse properly in the chamber. And since it operates like a conventional gasoline engine sometimes, it uses valve timing to lower the very high compression ratio so it doesn't reach combustion ignition in that mode. In practice, the Skyactiv-X runs in compression ignition mode most of the time. In practical terms, that means it drives like a torquey gasoline Skyactiv engine. The torque curve is broad and flat — diesel-like in that respect. That also means it can get away with using a six-speed transmission and a lower final drive for better response. There's enough grunt and economy together that Mazda can let the engine spin faster — at 60 mph, it's running at roughly 1,000 more RPM than a similar gas engine, with greater efficiency.

2016 Mazda MX-5 Miata gets 25 percent fuel economy boost

Just days after revealing full pricing and specs for each trim level of the 2016 MX-5 Miata, Mazda is spilling the beans on the roadster's fuel economy. As it turns out, the numbers show an impressive boost over the previous generation. All 2016 Miatas in the US are equipped with a 2.0-liter four-cylinder that makes 155 horsepower and 148 pound-feet of torque. With a six-speed manual, the EPA estimates fuel economy of 27 miles per gallon city, 34 mpg highway and 30 mpg combined. Buyers choosing the six-speed automatic, which is a $1,075 option (that you should absolutely not choose), are expected to get 27 mpg city, 36 mpg highway and 30 mpg combined. Compared to the previous-gen model with a six-speed manual, these latest numbers represent a 25-percent improvement in mileage. The boost in economy for the Miata likely comes from a variety of sources. Underneath the hood is one of Mazda's latest Skyactiv engines, and the loss of around 150 pounds from the last gen helps too. Production of the latest version of the famous roadster is already underway, and they should start arriving at dealers in the late summer. 2016 MAZDA MX-5 MIATA FUEL ECONOMY IMPROVES DRAMATIC 25 PERCENT VERSUS OUTGOING MODEL 24/04/15 - Mazda's Flagship Roadster Highlights Improvements Displayed by SKYACTIV Technology - IRVINE, Calif., April 24, 2015 -- Lighter, quicker and more nimble than its predecessor, the 2016 Mazda MX-5 Miata demonstrates the power innovation can have when re-engineering a roadster from the ground up. In addition to all of the aforementioned improvements the 2016 MX-5 has, fuel economy can now be added to the list, with MX-5 achieving an EPA-estimated 27 mpg city/34 mpg highway/30 mpg combined when equipped with the standard SKYACTIV-MT six-speed manual transmission (EPA-estimated 27 mpg city/36 mpg highway/30 mpg combined when equipped with the six-speed automatic). This performance represents a 25-percent increase in fuel economy versus the 2015 MX-5's EPA-estimated fuel economy when paired with the outgoing model's available six-speed manual transmission, highlighting the benefits of SKYACTIV Technology. "SKYACTIV Technology is more than a catchphrase for Mazda; it's a total effort to increase efficiency, improve performance, safety and technology and instill each Mazda vehicle with a directness and responsiveness that's unmatched in the segments in which our vehicles compete," said Jim O'Sullivan, president and CEO, Mazda North American Operations.
