Mazda engine technologies: Skyactiv-D and Skyactiv-X developments

Mazda is transitioning away from certain engine technologies as it prepares for a new generation of power units. The Skyactiv-X engine, introduced in 2019, utilized Spark Controlled Compression Ignition (SPCCI) technology to combine the efficiency of a diesel with the characteristics of a gasoline engine. Despite being a technical milestone in mass production, the Skyactiv-X did not achieve major market success.

Separately, the 2.2 Skyactiv-D turbodiesel engine remains a notable option for drivers seeking high torque and low fuel consumption in models such as the Mazda 3, Mazda 6, and CX-5. However, potential buyers of used vehicles should be aware of specific maintenance concerns, including DPF filter regeneration issues, fuel dilution of engine oil, soot accumulation, and potential lubrication system faults.
