Mazda is apparently preparing to retire its Skyactiv‑X power‑train technology. The Skyactiv‑X system merged the philosophy of gasoline and diesel engines into a single design. No other automaker has achieved that combination in mass‑produced vehicles before. The approach was presented as a unique blend of two competing engine concepts. The decision to end the programme suggests Mazda will shift away from that particular technology. The move marks the end of a distinctive engineering effort for the company.
