MAZDA’S revolutionary Skyactiv-X M Hybrid engine will go on sale in Australia tomorrow, 1 August, under the bonnet of the new Mazda3, with the CX-30 to get its own M Hybrid engine from September.
Achieving the high revving performance of a petrol engine with the fuel efficiency, torque and response of a diesel, Skyactiv-X M Hybrid offers a premium driving feel that enhances the refinement of Mazda’s new generation vehicles.
The world’s first production petrol unit to exploit the benefits of diesel like compression ignition, the new 2.0-litre Skyactiv-X M Hybrid is the next step in Mazda’s multi solution approach to reducing emissions.
It follows the launch of the highly efficient Skyactiv-G and Skyactiv-D engine technologies in 2012 and represents the first electrification technology on Mazda’s path to Sustainable Zoom-Zoom 2030.
Based on the high grade Astina variant, the new Mazda3 X20 Astina will be available on both manual and automatic, and priced from $40,590 (plus on-roads), while the CX-30 X20 Astina AWD will be priced at $46,490 (plus on-roads).
Skyactiv-X is characterised by Mazda’s revolutionary Spark Controlled Compression Ignition (SPCCI). This new engineering concept allows the engine to switch seamlessly between conventional spark ignition and compression ignition combustion.
It completes the process by using a spark to trigger both types of combustion in different ways. 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.
Skyactiv-X also features the Mazda M Hybrid system. Compact and efficient, the mild hybrid system features a belt-driven integrated starter generator (ISG) and a 24V lithium-ion battery.
It supports greater gains in fuel economy by recycling energy recovered during deceleration and powering the ISG, functioning as an electric motor, to assist the engine. To find out more, contact your local dealer, or visit mazda.com.au
