Fill up with petrol, drive with electricity

Nissan: E-Power is a key feature for the Japanese company. It combines a gasoline engine and an electric motor, but the vehicle is powered entirely by electricity.

Okay, Gasoline engine and electric motor under the hood, that is clearly a Hybrid, Also Nissan has combined both, but under the Name e-power. A Turbo petrol engine with three cylinders, which from its displacement of 1,5 liters produces a power of 116 kW/158 hp This is combined with a High-performance battery with a capacity of 2,1 kWh, a generator, an inverter and an electric drive, which in two-wheel mode, for example in the Qashqai 150 kW/190 hp perform.

The special thing about this construction: The gasoline engine generates electricity, which in turn via the inverter to the battery depending on the driving situation, to the electric motor or flows to both at the same timeThe wheels of the Nissan will be powered exclusively by e-powerThe result: Despite the petrol engine, the driver gets a purely electric driving experience and can enjoy a optimal fuel efficiency looking forward.

Nissan with e-power: Fuel up, drive electric

In plain language, this also means that a Nissan with e-power does not need to be plugged in at all, because the electricity is generated automatically via the petrol engine in the vehicleIn other words: fill up with petrol, drive electrically. The engineers achieve fuel efficiency by the petrol engine can always move in the optimal speed rangein order to reduce to generate electricityWhen you press the accelerator, the electric motor is activated to ensure faster progress.

This is ensured by the e-power energy management, which in situations of high acceleration or high speed, reduces the power generated by the petrol engine via the Inverter directly to the electric motorDuring deceleration, the kinetic energy is recovered and stored in the battery. In the case of the Qashqai, the Average consumption of 5,3 liters The 1,5-liter turbocharged gasoline engine operates with a variable compression ratio ranging from 8:1 to 14:1 to ensure optimal and economical performance depending on engine load.

For this, Nissan engineers have Actuator whose movement the Length of piston stroke changes depending on power requirementWhen little power is needed, the compression ratio is in the upper range. When more power is needed, the ratio is reduced to charge the battery or supply power directly to the electric motor. And because the ear listens, there's a so-called "Linear Tune" that adapts the sound to the required power.

Just one pedal is enough

In addition, the Nissan e-power models the e-Pedal system This also allows you to drive the Qashqai and the X-Trail drive with just one pedal, provided the driver activates the one-pedal system. Then the person behind the wheel can accelerate normally by pressing the accelerator pedalIf he takes his foot off, the system brakes automatically.

For those who are familiar with physics: The system brakes the vehicle at 0,2 g down to walking speed. There's a reason why it doesn't slow down to zero: Parking allows you to do so as gently as possible, just like in other vehicles. This might take some getting used to at first—but humans are creatures of habit.
