Mazda's 'Skyactiv-3' Engine Could Be As Clean As Some Electrics With 56% Thermal Efficiency

Mazda has been vocal about its plan to continue developing internal combustion engines despite a major industry push towards electrification and EVs. The company displayed its innovative Skyactiv-X engine last year, and now Automotive News reports that a next-generation motor—called Skyactiv 3—will offer efficiency levels that could yield overall CO2 output similar to that of some EVs. 

With Mazda’s Skyactiv-G engine having been out for a while now, and Skyactiv-X coming soon—that’s the one with the innovative Spark Controlled Compression Ignition technology—the company is apparently working to further increase internal combustion engine efficiency with a new generation of Skyactiv called “Skyactiv-3.”
