Mazda introduces its innovative Skyactiv-Z engine.

March 27, 2025 - Mazda introduced the Skyactiv-Z, a next-generation four-cylinder engine set to power the 2027 CX-5 SUV, focusing on high performance, efficiency, and meeting future emissions regulations.

Skyactiv-Z: The Future of Engine Technology

The Skyactiv-Z engine will replace Mazda's Skyactiv-X and Skyactiv-G engines, offering improved thermal efficiency and a broader operating range. A standout feature is its enhanced Spark Controlled Compression Ignition (SPCCI) technology, enabling a smooth transition between spark and compression ignition modes. This technology combines diesel-like fuel economy and torque with the cleaner emissions and high-revving characteristics of gasoline engines.

Meeting Future Emissions Standards

The Skyactiv-Z engine is being developed to comply with upcoming Euro 7 regulations in Europe, along with North America's LEV IV and Tier 4 emissions standards. Mazda aims to optimize combustion processes and utilize advanced heat shielding technologies for maximum efficiency and reduced emissions.

Wide Application Across Engine Platforms

Mazda plans to extend the innovations of the Skyactiv-Z to its six-cylinder engines and is also upgrading its rotary engines. This cross-platform application is part of Mazda’s integrated strategy to improve its powertrain technologies across a broad range of models.

Continued Focus on Internal Combustion

Despite the industry's growing shift towards electrification, Mazda remains committed to refining internal combustion engines. The Skyactiv-Z initiative reflects the brand's belief in maximizing the potential of traditional engine technologies while delivering efficient, enjoyable driving experiences and meeting environmental standards.
