Nissan's e-POWER is a series hybrid where the wheels are driven solely by an electric motor, and a gasoline engine generates electricity to recharge the battery. The third‑generation system, presented in September 2026, retains this EV‑like driving feel but introduces a purpose‑built engine family (HR14DDe and ZR15DDTe) and a new “5‑in‑1” electric unit that integrates the motor, reducer, inverter, increaser, and generator into a single compact module.
Depicts the ZR15DDTe turbocharged purpose-built engine, which corresponds to the purpose-built engine family mentioned in paragraph 1 of the article.
The 5‑in‑1 design uses flat‑wire windings to increase current flow and reduce gaps, a double‑sided cooling structure in the inverter, and optional silicon‑carbide power semiconductors that lower electrical losses. On the engine side, a long‑stroke configuration creates strong tumble flow, enabling stable combustion at high compression ratios and high exhaust‑gas recirculation. Nissan’s STARC concept shapes airflow toward the spark plug, and cold‑spray technology integrates the valve seat into the intake port to improve cylinder filling. Together these measures boost the engine’s thermal efficiency to 50 % and allow fixed‑point operation for optimal fuel economy.
Shows the inverter with double-sided cooling structure, matching the description of the 5-in-1 design's inverter cooling in paragraph 2.
Illustrates the 5-in-1 e-POWER electric unit integrating motor, reducer, inverter, increaser, and generator as described in paragraph 2.
Shows the motor's flat-wire windings, which increase current flow and reduce gaps as stated in paragraph 2.
Nissan claims the updated package significantly improves fuel efficiency and quietness compared with the second‑generation system used in the Qashqai, while maintaining the EV‑like driving experience. The modular approach also shares components with Nissan’s dedicated EV powertrains, reducing parts count and development costs. No independent test data are provided in the source, so real‑world performance claims rely on Nissan’s internal assessments.
