The Nissan e — POWER is a series hybrid powertrain introduced in 2016, combining a 1.2L or 1.5L petrol engine (HR12DE/HR15DE) exclusively as a generator with a 100–170 kW electric drive motor. It features no mechanical connection between the engine and wheels, delivering pure EV driving dynamics with the convenience of petrol refueling. Power output is determined solely by the electric motor, providing instant torque and quiet operation.
Fitted to models such as the Not…
All production years meet Euro 6d and Japan 2020 Post New Long-Term emissions standards depending on market (Nissan Emissions Compliance Doc. eP-EU6-16).
The Nissan e-POWER is a series hybrid powertrain engineered for compact and mid-size vehicles (2016-Present). It combines a small, efficient petrol engine acting solely as a generator with a high-output electric motor for propulsion. Designed to meet current emissions standards, it offers EV-like driving with the refueling convenience of petrol.

The Nissan e-POWER system was introduced across Nissan's B-segment and C-segment platforms with transverse mounting. This powertrain received platform-specific adaptations-a more powerful motor in the Qashqai and enhanced battery cooling in the Kicks-and from 2023 minor software revisions for improved energy management, creating minor calibration differences. All adaptations are documented in OEM technical bulletins.
Engine Finders UK Ltd, which operates EngineCode.uk, can pass your enquiry to engine suppliers in the UK. The service is for vehicles in the United Kingdom, with UK delivery or fitting. This is a commercially connected service, and sending an enquiry does not confirm diagnosis or compatibility.
Diagnostic reminder: If a technician has recommended replacing the engine, you can send an enquiry to engine suppliers in the UK. Confirm the diagnosis first: an engine-code record does not diagnose a fault.
The e-POWER's primary reliability risk is lithium-ion battery capacity degradation in vehicles subjected to sustained high ambient temperatures. Nissan internal service data indicated a notable rate of reduced electric range complaints in hot climates after 80,000 km, while common owner reports highlight 12V auxiliary battery failures as a secondary concern. Infrequent software updates can lead to suboptimal energy management, making adherence to the maintenance schedule critical.
Analysis derived from Nissan technical bulletins (2016-Present) and aggregated owner-reported failure data (2016-2023). Repair procedures should follow manufacturer guidelines.
The most common questions about engine codes, what they mean, how to find them and how this database works
The e-POWER system is generally very reliable, leveraging proven Nissan EV and engine technology. Its main long-term concerns are the 12V auxiliary battery and potential traction battery degradation in hot climates. With regular maintenance and software updates, the system is designed for the vehicle's full lifespan. The lack of a complex transmission is a significant durability advantage.
The most frequent issues are premature failure of the 12V auxiliary battery, reduced capacity of the lithium-ion traction battery in hot climates, and overheating of the power inverter due to cooling system neglect. Engine generator mount wear can also cause NVH issues. These are documented in Nissan service bulletins and owner reports.
The e-POWER system is currently available in the Nissan Note (E13, 2016-Present), Nissan Kicks (P15, 2020-Present), Nissan Qashqai (J12, 2022-Present), and Nissan X-Trail (T33, 2022-Present). It is Nissan's flagship electrified powertrain for global markets outside North America.
No, the e-POWER system cannot be meaningfully tuned for more power. The electric motor's output is fixed by its hardware and tightly controlled by proprietary software for safety and battery longevity. Any attempts to modify the system would likely void the warranty and could cause serious damage to the power electronics.
Fuel economy is excellent for its class. Expect around 3.8–4.5 L/100km (74–63 mpg UK) in combined driving for a Note e-POWER. The Qashqai e-POWER returns around 5.5–6.2 L/100km (51–46 mpg UK). Actual consumption depends heavily on driving style, as aggressive acceleration draws more power from the generator.
No. The e-POWER system has no traditional multi-speed gearbox. Power from the electric motor is delivered directly to the wheels through a single-speed reduction gear, providing smooth, seamless acceleration without any gear shifts, just like a pure electric vehicle.
The petrol generator engine requires API SN or SP grade 0W-20 engine oil. Using a high-quality, low-viscosity synthetic oil is crucial for maximizing the generator's efficiency and minimizing friction, as it operates frequently at varying loads to charge the battery.
