1. Electric motor propulsion
Electric motor propulsion constitutes the fundamental driving force within the “E-POWER + Internal Combustion: Nissans Innovative Drive System”. Its presence is not merely an ancillary feature but a core architectural element that dictates the entire vehicle’s driving characteristics. Unlike conventional internal combustion engine vehicles, where the engine’s output is mechanically linked to the wheels, this system employs the electric motor as the sole means of delivering torque to the drive wheels. This separation provides immediate torque response, resulting in smooth and linear acceleration. As a direct result, the vehicles acceleration and overall driving experience exhibit qualities similar to those of a full electric vehicle, irrespective of the operational state of the internal combustion engine.
The implementation of electric motor propulsion necessitates a specific control system that manages the interplay between the battery, electric motor, and engine-generator unit. Consider, for instance, a situation where the driver demands rapid acceleration. The control system immediately signals the electric motor to draw power from the battery. Simultaneously, the internal combustion engine activates to replenish the battery charge, ensuring sustained power delivery. This orchestration of power sources guarantees consistent performance, even under demanding driving conditions, demonstrating the crucial role of electric motor propulsion within the overall system architecture.
In summary, electric motor propulsion is indispensable to the functionality and driving experience of this system.

2. Engine as generator
The operational distinction of “E-POWER + Internal Combustion: Nissans Innovative Drive System” lies in its utilization of the internal combustion engine solely as a generator. This represents a significant departure from conventional hybrid architectures where the engine may contribute directly to wheel propulsion alongside the electric motor. In this system, the engine’s sole function is to drive a generator, which produces electricity to either power the electric motor directly or charge the battery. This design choice has profound implications for efficiency and emissions, as it allows the engine to operate within a narrow, optimized band of revolutions per minute (RPM) and load, independent of the vehicle’s immediate power demands.
Consider a scenario where a driver is navigating stop-and-go city traffic. In a conventional hybrid, the engine would repeatedly cycle on and off, with frequent variations in RPM and load. This intermittent operation often leads to lower efficiency and increased emissions. In contrast, with the engine acting solely as a generator, it can maintain a more consistent output. The control system manages the flow of electricity between the generator, battery, and electric motor to provide the necessary power to the wheels. This ensures that the engine operates efficiently, producing electricity at a steady rate while the electric motor handles the fluctuating power demands of driving. This method also facilitates advanced noise and vibration mitigation strategies since engine speed doesn’t correlate directly to vehicle speed and acceleration.
In conclusion, the “Engine as generator” concept is foundational to the performance characteristics of “E-POWER + Internal Combustion: Nissans Innovative Drive System”. This specific engine application directly causes improved efficiency, reduced emissions, and a driving experience more akin to a fully electric vehicle.
