Mazda is breaking the mold in the automotive industry by focusing on the development of new gas engines, a rarity in a market dominated by electric vehicles. The Japanese automaker is working on what they claim to be the “ideal internal combustion engine” with their latest innovation, the Skyactiv-Z engine.
Announced last November, the Skyactiv-Z engine is set to debut in the next-generation Mazda CX-5, scheduled for release in late 2027. This revamped SUV will feature an inline-four 2.5-liter gasoline engine along with a hybrid setup developed in-house. The engine is being designed to meet stringent emission standards such as Euro 7 regulations in Europe and LEV IV and Tier 4 standards in North America.
Mazda boasts that the Skyactiv-Z engine will offer higher thermal efficiency and a wider range compared to their existing Skyactiv-G and Skyactiv-X engines. The knowledge gained from perfecting the combustion process will also be applied to larger six-cylinder engines and rotary engines. The goal is to enhance fuel economy, power delivery, and emissions control.
The Skyactiv-Z engine utilizes Spark Controlled Compression Ignition (SPCCI) technology, which allows for seamless switching between spark ignition and compression ignition combustion. This technology aims to achieve diesel-like fuel efficiency and initial power delivery, combined with the high rpm performance and cleaner emissions of gasoline engines.
With the introduction of the Skyactiv-Z engine, Mazda plans to reduce its total engine variants by over 50 percent. Despite the engine running cleaner, there will be no compromise on power output. This innovation ensures that Mazda vehicles will comply with strict regulations without sacrificing performance.
Furthermore, Mazda is also focusing on the development of rotary engines as range-extenders for electric vehicles. The MX-30 e-Skyactiv R-EV crossover already features an 830-cc rotary engine as a generator, with plans for a more powerful two-rotor setup for a future US-bound vehicle. The company’s commitment to rotary engines is evident in concepts like the Iconic SP, hinting at exciting possibilities for the future.
In conclusion, Mazda’s dedication to innovation in gas engine technology with the Skyactiv-Z engine and rotary engine development showcases their commitment to delivering high-performance, efficient, and environmentally friendly vehicles. As the automotive industry shifts towards electric vehicles, Mazda is carving out a unique path with their groundbreaking engine technologies.
