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 Note (E13), Kicks (P15), and Qashqai (J12), the e-POWER system was engineered for urban efficiency and responsive performance without range anxiety. Emissions compliance is met through the engine operating at optimal efficiency to generate electricity, allowing compliance with Euro 6d and Japan's 2020 Post New Long-Term standards.
One documented service concern is degradation of the lithium-ion battery pack capacity in extreme climate conditions, referenced in Nissan Technical Bulletin NTB21-055. This issue, often attributed to sustained high ambient temperatures, can lead to reduced electric-only range and increased engine generator usage. Nissan has implemented thermal management enhancements in 2023+ models.

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 electric motor provides instant, silent torque ideal for city driving, with the petrol engine only running to recharge the battery, minimizing noise and vibration. Using the specified 0W-20 oil is critical for the engine-generator's efficiency and longevity. The small battery is designed for power delivery, not long EV range; expect 1-3 km of pure EV driving. Battery degradation in hot climates can reduce efficiency; parking in shade and using cabin preconditioning while plugged in (if available) helps preserve battery health per NTB21-055. The system requires no traditional transmission fluid changes.
Oil Specs: Requires API SN/SP 0W-20 for optimal generator efficiency (Nissan Owner's Manual OM-eP-16).
Emissions: Euro 6d and Japan 2020 Post New Long-Term certification applies to all production years (Nissan Emissions Compliance Doc. eP-EU6-16).
Power Ratings: Electric motor output measured under JIS D 1001 standards. Engine power is not rated for wheel drive (Nissan Group PT-2023).

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.
Locate the "e-POWER" badge on the rear liftgate or front fenders. The engine code for the generator is stamped on the block (HR12DE or HR15DE) near the oil filter (Nissan SM-HY-16). Visually, the engine bay contains a conventional petrol engine but lacks a traditional transmission, replaced by a large silver power inverter unit. Critical differentiation from pure EVs: The presence of a petrol fuel filler cap and exhaust system. VIN decoding: The 8th digit for e-POWER Qashqai is 'E'.
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.
