Watch the video below to see how Mazda’s cylinder-deactivation technology works, improving real-world fuel efficiency without sacrificing driving performance. Mazda’s breakthrough solution to compensate for this is to use a fulcrum inside the six-speed SKYACTIV-DRIVE automatic transmission, helping ensure seamless transition between two- and four-cylinder operation. The challenge with four-cylinder deactivation is that an engine running on two cylinders is more likely to cause vibration. The new cylinder-deactivation system can be found in the latest SKYACTIV-G 2.5-liter engine that delivers 187 horsepower and 186 lb-ft of torque.Īvailable on the 2018 Mazda CX- Mazda6, Mazda is the only automaker to offer cylinder-deactivation technology on a four-cylinder engine in North America. Maintain the 2.0 Skyactive well use quality oils, change fluids on time, and fix problems if and when they occur. However, maintenance is one key component owners have control over. Sometimes, that means burning fuel when you don’t need to, which is why Mazda’s engineers went back to the drawing board to introduce a new cylinder-deactivation technology for 2018 that can cut down on fuel-consumption in certain operating conditions. Some Mazda 2.0L Skyactiv engine reliability simply comes down to the luck of the draw. Usually, “running on all cylinders” is considered a good thing but not all the time.
