Nissan’s E-Power engine is an electrified powertrain that debuted in 2022 on the Qashqai and later on the X-Trail. It consists of a thruster turbo petrol with generator function current which recharges the lithium ion battery (lighter and smaller in size) and simultaneously powers the electric traction motor, what actually moves the car. It does not require plug charging and allows you to travel up to 1,000 km on a full tank of petrol.
E-Power Nissan, the serial / parallel hybrid
The e-Power propulsion system It’s not exactly new at Nissan, which had already introduced it in 2016 on the Note, the best-selling car in Japan in 2018. It’s a “serial hybrid” with electric and combustion engine that work independently in parallel and in series. In reality it can also be defined as a mixed one serial/parallel because in some moments battery and heat generator they feed the electric motor in parallel with current.
e-Power engine on the Nissan Qashqai
E-POWER debuted in 2022 on the Qashqai. The components of the e-Power engine are essentially five: there is the combustion engine 1,500 3-cylinder turbo that delivers 158 horsepower, optimized for maximum efficiency and which sends traction to the electricity generator; the energy produced is managed by an inverter which distributes it between the 140 kW (190 horsepower) traction motor and the lithium ion battery 2 kWh. During the regeneration phase, the energy produced by the traction motor (reaches 66 kW, 90 hp in regeneration) is sent to the battery. When the battery is 100% charged, the energy produced is dissipated by the combustion engine, driven by the generator powered by the energy produced by regeneration. When going downhill with a charged battery, regenerative braking in release is guaranteed thanks to the combustion engine which acts as an engine brake.
The Qashqai e-Power it does not have plug-in chargingthe wholeenergy is produced exclusively by the motor generator on board that it can simultaneously charge the battery and power the electric motor.
This is a different frontier of electrification with on-board electricity production with the benefits of an electric car in terms of driving pleasure in a car not weighed down by the mass of large lithium ion batteries.
How does Nissan e-Power electric motor work?
In the e-Power system the petrol engine it is used exclusively for generate electricitywhile the wheels are driven Alone from the electric motor. This means that the heat engine always works in its own way optimal range, maximizing fuel efficiency and reducing CO2 emissions. The propulsive thrust is entirely provided by the electric motor which takes power from the battery or directly from the generator.
Thanks to this solution the petrol engine almost always works at optimal rotation speeds: obviously it revs up slightly when you ask for more power. However, this variation in rpm will be gradual with less sudden transients: the greater current necessary for starting off, accelerating or tackling a climb is immediately provided by the lithium battery which acts as a “buffer” and then comes the support of the motor generator.

How to drive the Qashqai e-Power
The Quashqai e-Power drives practically like an electric car, but with a slight noise coming from the 1,500 petrol engine. Obviously it has the regenerative braking which allows you to recover even a small portion of electricity. It has three driving modes, “S Mode”, “Normal Mode” and “ECO Mode”.
The new Qashqai e-POWER also takes advantage of technology e-Pedal Stepwhich allows you to accelerate and brake using the accelerator pedal only. The system, which is activated via a special button on the central console, is very useful and convenient in driving situations characterized by frequent speed variations, thus preventing the driver from continually moving his foot between the brake and accelerator.
When the accelerator pedal is released, e-Pedal Step brakes the car with a deceleration that can reach up to 0.2g, just enough to make the brake lights come on. The system reduces speed, but without stopping the car completely, this is to facilitate parking maneuvers and at low speeds.
ADVANTAGES? you are never left stranded, you don’t have to worry about electric charging.
→ DISADVANTAGES for electric purists it’s not exactly the best given that it “roars” and emits (reduced) exhaust emissions.
Below you can see the differences between an electric car, the Nissan with e-Power engine and a traditional hybrid.
From Nissan e-Power systems over 16,000 have been sold in Europe. The system is similar to the one used by BMW in the i3 Range Extender, Opel Ampera and Chevrolet Volt.
