Mazda Australia has recently provided details of their new Skyactiv-X M-Hybrid powertrain. It will be available in August with the Mazda3 (the 2020 World Design Car of the Year) and in the CX-30 from September, with that car also a finalist in the WCOTY. It will, for the moment, be available only in the top of the range Astina, dubbed X20, for each trim level. Pricing for the Mazda3 X20 Astina starts from $40,590 with it being available in both manual and auto, and the CX-30 X20 Astina starts from $46,490. Both are before dealer delivery and government charges at the time of writing.
The powerplant is a continuation of Mazda’s search to improve power, torque, and fuel consumption. The new engine is the world’s first mass production unit that combines compression ignition like a diesel, the torque of a diesel, and the free revving ability of a petrol nature.
Mazda has developed a proprietary ignition system. It’s called Spark Controlled Compression Ignition, or SPCCI. The engine can fire via a compression or traditional spark ignition. This is how Mazda says it works: “In SPCCI mode, a split injection process creates separate zones of fuel-air mixture inside the combustion chamber. First, a very lean fuel to air mixture is injected into the combustion chamber during the intake stroke, then a zone of atomised fuel is precisely injected directly around the spark plug during the compression stroke. The small injection of atomised fuel directly around the spark plug builds a richer core. When the spark fires, it ignites this core of fuel and air. This increases pressure in the combustion chamber to the point where the lean mixture rapidly combusts.”
Vinesh Bhindi, the managing director of Mazda Australia is excited by the new engine. “With every customer’s circumstances being unique, we need to offer a variety of ways to reduce vehicle emissions to suit individual needs and lifestyles. Skyactiv-X offers customers a lower emission engine option, while retaining the same joy of driving that Mazda vehicles have always offered.”
