Nissan Juke: New hybrid powertrain offered

Nissan Juke 2022

Nissan has added a new powertrain to the Juke line-up with the introduction of a hybrid system combining a 1.6 petrol engine and an electric motor.

Nissan says that, subject to homologation, fuel consumption is reduced by up to 40% in the urban cycle, and up to 20% on the combined, with fuel economy of 54mpg and emissions of 118g/km.

Guillaume Cartier, chairperson of Nissan AMIEO region, said: “Nissan’s electrified product strategy is gaining momentum and the Juke hybrid which will join the line-up later this year will represent another milestone on our strategic ambition to have fully-electrified range by 2023.”

Utilising the engineering strengths found within the Alliance, the Juke hybrid powertrain consists of a new generation, Nissan internal combustion engine specifically developed for working in a hybrid powertrain application. It produces 69kW (94hp) and 148Nm of torque.

On the electric side, Nissan supplied the main electric motor which produces 36kW (49hp) and 205Nm of torque, while Renault provided the 15kW high voltage starter/generator, the inverter and the 1.2kWh water-cooled battery, as well as the gearbox.

The net result is a powertrain providing 25% more power than the current petrol engine option.

To reduce friction, this gearbox uses dog clutches instead of conventional synchroniser rings to shift the 4 “ICE” gears and 2 “EV” gears.

Additionally, to reduce friction, this gearbox does not use a clutch.

All vehicle starts are 100% electric, and the two EV motors are used in combination to synchronise the gears, delivering a smooth, connected and responsive acceleration.

The gearbox is controlled by an algorithm, managing the shift points, battery regeneration, as well as the advanced series-parallel architecture.

The powertrain can navigate through different hybridisation type possible (series, parallel, series-parallel) according to acceleration and power requirements seamlessly and without any driver input.

When slowing down, the electric motor will act as a generator and capture kinetic energy, turning it into electricity to be stored in the hybrid propulsion battery.

As with the Leaf pure EV, the Juke hybrid will be equipped with Nissan’s e-Pedal step system, which, when activated, allows the progress of the car to be controlled using the accelerator pedal.

When the foot is lifted from the accelerator, moderate braking is applied (up to 0.15g) and will decelerate the Juke to creep speed (~5kph/3mph).

Additional foot braking may sometimes be necessary to decelerate and is needed to achieve full stop.

The button for e-Pedal is positioned in the centre console, behind the electric parking brake button, while the button to activate 100% EV mode is between two of the central air-vents. When e-Pedal and EV mode are activated, visual reminders appear at the bottom of the combimeter screen.

The boot space is 354 litres, a slight reduction of 68 litres compared to the petrol version, as a consequence of the packaging of the 1.2kWh battery pack.

With rear seats folded, load space is 1,237 litres, while rear knee room remains unchanged at 553mm.
