Qashqai e-POWER, the Nissan revolution
Written by aquitodovale

Nissan Qashqai e-POWER can also be ordered in Italy, it is the car that gave birth to the crossover segment and that, since its launch on the market, is registering endless success. Today it is equipped with an electrified engine that is unique in the automotive world, a technology that we have never seen before but which has been enjoying great success in Japan for years.

There are no equals in the market for this type of engine, which consists of a 100% electric motor that moves the vehicle’s wheels and a heat engine that produces electricity. Nissan Qashqai e-POWER travels more than 1,000km on a single tank of petrol. This novelty is ideal for European customers, who are always very attentive to driving pleasure, efficiency and the possibility of unlimited travel in all contexts: urban, sub-urban and extra-urban. Nissan’s e-POWER has a great goal: to market the best electrified solution available, alternative to diesel and true element of transition towards 100% electric mobility.

e-POWER Nissan: unique engine on the market

The 190 HP electric motor moves the car’s wheels and guarantees the driving pleasure typical of an electric vehicle, without having to recharge the car at the power socket, as is the case with any EV vehicle. How is it possible? The electricity needed for traction is produced by a refined turbo petrol engine three 1.5-liter cylinders and 158 HP of power, capable of guaranteeing maximum efficiency thanks to the variable compression ratio.

How the e-POWER engine works

In the system, the electric motor moves the wheels of the car, just push the accelerator pedal all the way down to give the driver the same sensation as driving a high-performance sedan, but with greater fluidity and progression in the delivery of power.

The electricity needed for traction is produced by the heat engine, the new Nissan e-POWER system for Europe in fact does not need to be recharged at the plug, the energy that is released by the heat engine passes to the inverter and from here it can be transmitted to the battery, the electric motor or both. The thermal power is therefore never transmitted directly to the wheels.

A very sophisticated control unit controls the system and optimizes the energy flows based on a number of parameters, including the state of charge of the battery, the driving conditions and the demand for motive power, and maximizes the time in which the heat engine remains off. When the driver proceeds at low speed, the energy produced by the internal combustion engine goes partly to the electric motor and partly to the battery and when this is fully charged, the internal combustion engine switches off and the car proceeds only in electricmoved by the charge of the battery itself.

The control unit also manages the regeneration phase and thus – when the accelerator pedal is released or the brake is applied – the electric motor transforms the vehicle’s kinetic energy into electrical energy, which recharges the battery.

Emissions and consumption

One of the strengths of Nissan’s new e-POWER system is undoubtedly efficiency: low consumption and low emissions make it the ideal system for all types of journeys, but especially in urban and sub-urban contexts, where European crossover customers drive 70% of their time.

The wheels are driven only by the electric motor, therefore the heat engine that produces energy can operate in an optimal range of number of revolutions, minimizing consumption and CO2 emissions. The heat engine boasts very high efficiency thanks to a sophisticated technology that allows for a variable compression ratio, automatically adjusted according to the demand for motive power. When driving in the city, where frequent restarts and braking facilitate energy regeneration, the system tends to keep the heat engine off more often, with approximately 65% ​​fewer starts than in a traditional hybrid system.

The 1.5-liter, 158 HP three-cylinder turbo gasoline thermal unit is derived InfiniteNissan’s premium brand, developed specifically for this application and featuring Nissan’s proprietary variable compression ratio technology.

Through an additional crank mechanism connected to the crankshaft, the system can vary the volume of the combustion chamber seamlessly. A control unit detects the driving conditions of the vehicle and the action on the accelerator pedal, automatically and instantly selecting the most suitable compression ratio in a range between 14: 1 and 8: 1, optimizing performance and therefore performance and efficiency.

Explaining better with an example made directly by Nissan: traveling at a constant speed, the compression ratio is kept at high values, to reduce the level of emissions and consumption. In the phase of strong acceleration, on the other hand, the system chooses low compression ratios, thus favoring performance. Switching between the different compression ratios is smooth and automatic and requires no driver intervention.

What is e-Pedal Step technology

The new Qashqai e-POWER is equipped with the e-Pedal Step, a new technology that allows the driver to accelerate and slow down using only the accelerator pedal. The system is activated thanks to a special button located on the center console, it is very useful and comfortable in driving situations characterized by frequent speed variations. When you release the pedal, the e-Pedal slows the car, but without stopping it completely, thus facilitating parking and low speed maneuvers.

Safety and comfort on board the Nissan Qashqai e-POWER

The system ProPILOT with Navi-link it regulates acceleration, braking, stop and restart in the single lane, is able to read road signs and automatically adapt the speed at which the vehicle is moving. That’s not all: it is a system that can also acquire data from the navigator and regulate speed on curves or on motorway exit ramps.

The car boasts a very rich on-board technological equipmenta, there is the latest generation 10.8 “Head Up Display (HUD), which projects information on the itinerary, traffic or driving assistance, a new 12.3” high definition digital multifunction instrument cluster and a new infotainment and navigation system with a 12.3 ”HD digital touch screen.

Nissan Qashqai e-POWER: list prices

The car is available in five different trim levels: Acenta, Business, N-Connecta, Tekna and Tekna +. List prices start from 36,270 euros. It can already be ordered from Nissan dealerships and the first deliveries are expected in October 2022.
