Efficient engine thanks to Alliance synergies
The new hybrid powertrain fully leverages the engineering strengths found within the Alliance.
The JUKE hybrid powertrain consists of a new generation, state-of-the-art 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 highly innovative gearbox. The net result is a powertrain providing 25% more power than the current petrol engine option, with a fuel consumption reduction of up to 40% in urban cycle, and up to 20% combined.

Smart automatic gearbox
Key to the driving pleasure at the heart of the Nissan JUKE Hybrid is an advanced low friction multi modal gearbox that provides optimal use of the propulsive power, whether electric, petrol engine, or both.
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 2 EV motors are used in combination to synchronise the gears, delivering a smooth, connected and responsive acceleration.
The gearbox is controlled by an advanced 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. As a result, driver will enjoy trouble free responsive acceleration as well as efficient low emissions – the best of both worlds.
