Mazda is planning to discontinue its innovative Skyactiv-X engine in some markets as it shifts focus to a new hybrid powertrain called Skyactiv-Z. This change will start impacting Mazda3 buyers in Europe and the UK next year.
Skyactiv-X Engine’s Limited Role Moving Forward
For the upcoming model year, Mazda will drop the 2.0-liter Skyactiv-X engine option from the Mazda3 in Europe and the UK. Buyers will be left with only the 2.5-liter Skyactiv-G engine, which offers less power but comes with both manual and automatic transmissions. Meanwhile, the Skyactiv-X engine will continue in the CX-30 for now, but its future there remains uncertain as Mazda moves toward replacing its small-engine lineup.
What Set the Skyactiv-X Apart?
Introduced in 2019, Mazda’s Skyactiv-X engine featured a rare and experimental technology called Spark Controlled Compression Ignition (SPCCI). This system combined elements of diesel and gasoline engines, allowing the engine to run on a very lean air-fuel mixture. Unlike traditional engines, Skyactiv-X uses a spark to control the compression ignition, improving power and efficiency.
Other automakers like Ford and Honda experimented with similar homogeneous-charge compression-ignition (HCCI) technology, but none managed to bring it to production like Mazda did with Skyactiv-X. Despite this innovation, Mazda never offered the engine in the United States and limited its use globally.
The Road Ahead with Skyactiv-Z Hybrid
Mazda is already developing the next step in its engine technology: the Skyactiv-Z hybrid powertrain. This system pairs a new 2.5-liter four-cylinder engine with Mazda’s own hybrid technology. The new powertrain is expected to debut in the CX-5 crossover by the end of next year.
The Skyactiv-Z will build upon the learnings from Skyactiv-X. It is set to improve the combustion of even leaner fuel mixtures and will include new heat-insulation technology that converts wasted engine heat into usable power, increasing overall efficiency.
This transition marks Mazda’s move towards electrified powertrains while keeping some of the unique combustion technology it pioneered. Whether Skyactiv-X will remain longer in the CX-30 or disappear soon after is still unclear.
