SKYACTIV-X  – The Revolutionary Combustion Engine

Featuring Spark-Controlled Compression Ignition, a never-before-seen combustion method, Mazda’s SKYACTIV-X engine represents the second step in Mazda’s quest to develop a petrol engine with the ideal internal combustion mechanism.


Developing compression ignition for petrol engines has long been a goal of engineers. In the SKYACTIV-X, spark plug ignition is used to control compression ignition, resulting in dramatic improvements across a range of important performance indicators.

The SKYACTIV-X is a ground-breaking new engine exclusive to Mazda in which the benefits of a spark-ignition petrol engine—expansiveness at high rpms and cleaner exhaust emissions—have been combined with those of a compression-ignition diesel engine—superior initial response and fuel economy—to produce a crossover engine that delivers the best of both worlds. Coming after Mazda’s SKYACTIV-G petrol engine and SKYACTIV-D diesel engine, this third SKYACTIV engine has been given the new name of “X” in recognition of this dual role.

At Mazda, we believe that there is still ample room for further evolution of the internal combustion engine and that this technology has the potential to contribute in a major way to conservation of our global environment. Based on Mazda’s corporate vision of protecting our beautiful planet while enriching people’s lives through the “joy of driving,” we plan to continue on our ceaseless quest to develop the ideal combustion engine.



The range where the engine is able to deliver excellent fuel economy has been dramatically expanded with the use of the SKYACTIV-X, meaning that this system is able to deliver lower fuel consumption than ever before in a whole range of driving scenarios, including city driving, long-distance driving on expressways and more.

Unique to Mazda, the SKYACTIV-X is a new kind of combustion engine that combines the advantages of gasoline and diesel engines to achieve outstanding environmental performance and uncompromised power and acceleration performance. This revolutionary technology represents the start of an exciting new stage in our quest to develop the ideal internal combustion engine. Fully supporting the Jinba Ittai driving experience Mazda aims to provide, SKYACTIV-X was developed in consideration of our planet and all who live here.
