The QASHQAI’s e-POWER system consists of a high-output battery that is complemented by a variable compression ratio 1.5-litre three-cylinder turbo-charged petrol engine generating 116kW, a power generator, inverter and 140kW electric motor of similar size and power output as found in Nissan's LEAF electric vehicle. The petrol engine generates electricity, which can be transmitted via the inverter to the battery pack, the electric motor or both, according to the driving scenario.

What sets this powertrain apart is that the electric motor delivers power directly to the wheels, so its response is instant and linear. The new QASHQAI's e-POWER system was conceived to deliver a pleasurable, effortless and smooth driving experience, without the need to recharge.

At the heart of Nissan's QASHQAI e-POWER system is a 1.5-litre three-cylinder turbo-charged variable compression 116kW petrol engine.

First used by Nissan's premium brand Infiniti, the engine's variable compression capability is a unique feature in an internal combustion engine and allows it to adjust compression ratio to balance performance and economy, depending on the engine load. Ahead of its first introduction in 2018 with Infiniti, it was listed as being among the world's 10 best engines by Ward's, a US-based automotive consultancy.

The variation in compression ratio ranges between 8:1 and 14:1. This is achieved by the movement of an actuator which changes the length of the piston stroke according to the demand for power.

During low power demand scenarios – such as constant speed with a good state of charge in the battery - the compression ratio will be at the higher range which optimises consumption and emissions. Under high demand — involving more spirited driving, to charge the battery or to supply power directly to the motor — a lower compression ratio will be activated which will maximise the engine's power output. The transition between differing compression ratios is seamless, with no input required from the driver.

Key to the development of the e-POWER system for the QASHQAI was the need to ensure the driving experience gave a "connected" sensation, where the petrol engine speed remains relative to the QASHQAI's road speed. The disparity between engine speed and road speed is a phenomenon that drivers and passengers find unsettling. For example, a sudden rise in engine revs without a commensurate increase in speed is perceived as frustrating and "disconnected" by occupants. Engineers at Nissan Technical Centre Europe (NTCE) in the UK and Spain collaborated in developing a system called "Linear Tune". This feature governs the petrol engine and progressively increases the speed of the 1.5-litre engine to meet the motor's energy demands as the car accelerates, ensuring there is no "disconnect" between what the occupants experience in terms of performance and sound.

Similar to the LEAF, the new QASHQAI e-POWER benefits from a ‘one-pedal' driving experience called e-Pedal Step^>. Designed to take the repetitive strain out of stop-start urban driving, where the driver is frequently moving their foot between the accelerator and brake, e-Pedal Step> allows drivers to accelerate and brake using just the accelerator.

The system must first be activated by the switch on the centre console and once engaged, the accelerator will deliver acceleration as usual. Upon release of the accelerator, e-Pedal Step will brake the QASHQAI at 0.2g, enough to illuminate the brake lights, and reduce the speed down to a "creeping" speed, not a complete stop. This ensures low-speed parking manoeuvres are as smooth as possible. Drivers will quickly adapt their accelerator pedal inputs to maintain smooth progress, ensuring urban driving is more intuitive and less demanding.

The advantage of the e-POWER system is that the engine runs within its optimal range and best compression ratio. Thanks to the unique powertrain, there's no delay in the delivery of torque as can be the case in a traditional hybrid, where there can be a sudden rise in engine speed as it responds to the accelerator demand for immediate acceleration. The instant response of the e-POWER system delivers a unique and exciting driving experience.

To maximise performance, in high acceleration or high speed situations, the energy management control unit within the e-POWER system can send the power generated by the 1.5-litre engine directly to the electric motor, via the inverter, to bolster the electricity supply which is coming from the battery.
