Mazda is phasing out its Skyactiv-X engine, a unique powertrain that utilizes Spark Controlled Compression Ignition (SPCCI) technology. The engine, which debuted in 2019 for the Mazda3 and CX-30, will soon be limited to the CX-30 model in the United Kingdom and Europe. For the upcoming model year, the 2.0-liter Skyactiv-X option will be removed from the Mazda3 lineup, leaving only the 2.5-liter Skyactiv-G engine available.
The automaker is currently developing a successor known as the Skyactiv-Z hybrid powertrain. This new system will combine an all-new 2.5-liter four-cylinder engine with an in-house hybrid setup. The technology is scheduled to debut in the new CX-5 crossover by the end of next year. The Skyactiv-Z aims to improve upon SPCCI by combusting even leaner fuel mixtures and incorporating heat-insulation technology to convert waste heat into power.
