mild hybrid powertrain

mild hybrid technology

Discover mild hybrid technology, the entry-level hybrid that offers a smoother driving experience while reducing your fuel consumption.

mild hybrid advantages

This technology lets you keep the same habits and driving pleasure while helping to reduce fuel consumption.

lower fuel consumption

Use less fuel with mild hybrid technology. By performing manoeuvres and starting in electric mode, the combustion engine is used less and you save up to 6 l/100 km.

smooth driving

Vehicles equipped with mild hybrid technology offer smoother driving with electric power assistance when you start and accelerate. Enjoy immediate starting with start & stop, more torque and less stalling.

lower CO₂ emissions

Reduce your CO₂ emissions by up to 20%* with mild hybrid technology. It helps reduce use of the combustion engine when you start and accelerate.

mild hybrid at Renault

how mild hybrid works

Mild hybrid technology offers a dual function: an engine function during acceleration, and an alternator function during braking.

engine function

For greater driving comfort and power, the combustion engine is backed up by an electric battery (12 or 48 V) during starting and acceleration.

alternator function

The battery that backs up the combustion engine works by recovering energy when you brake and slow down.

3 types of mild hybrid

Renault offers 3 types of mild hybrid with different battery performances and powers. Choose the mild hybrid powertrain that best suits your needs.

your questions about mild hybrid technology

What are the characteristics of mild hybrid technology?

Mild hybrid powertrains are not E-Tech technology since you cannot drive fully electric. It involves mild hybridisation of the vehicle, which provides electrified assistance to the combustion engine only during starting and acceleration to reduce consumption and improve performance.

They offer more flexible and dynamic driving whilst allowing up to 20% fuel savings compared with an equivalent non-electrified petrol engine.

What are the advantages of mild hybrid technology?

Mild hybrid engines consume 10% to 20% less fuel than an equivalent combustion-powered vehicle.

What are the differences between mild hybrid and mild hybrid advanced?

The mild hybrid engine is equipped with a 12V Lithium-ion battery with fuel consumption reduced by up to 10% compared with a combustion engine.

The advanced mild hybrid engine is equipped with a 48V Lithium-ion battery with fuel consumption reduced by up to 20% compared with a combustion engine.

These two technologies are available in the Renault range with different engine blocks and power levels depending on the model.

Mild hybrid, full hybrid E-Tech or plug-in hybrid, what are the differences?

There are 3 categories of hybrid vehicles: full hybrid, plug-in hybrid and mild hybrid. They all have a combustion engine and at least one electric motor, as well as a traction battery. But the traction, the type of transmission, the charging method, their fuel consumption and their environmental impact differ.

A mild hybrid operates with the combustion engine always running, with the electric motor supporting it occasionally. Mild hybrid engines consume up to 10% (mild hybrid) or up to 20% (mild hybrid advanced) less fuel than an equivalent combustion-powered vehicle. The transmission can be manual or automatic.

Full hybrid and plug-in hybrid vehicles systematically start in electric and can drive fully electric. They both switch intelligently between the electric and combustion powertrains.

The difference between them lies in the capacity of their battery and the charging method.

With full hybrid E-Tech technology, you do not need to plug your vehicle into a socket to get power. You recover energy during driving phases through regenerative braking. This means that you can reduce your fuel consumption by up to 40% and drive electric up to 80% of the time in town.

With E-Tech plug-in hybrid technology, to optimise your consumption, it is important to charge your vehicle daily using a standard socket or at a charging point. With a greater driving range, you can spend most of your everyday journeys driving 100% electric. The technology therefore saves up to 75% fuel (in WLTP cycle).

What is a hybrid car?

A hybrid car combines two types of powertrain: a combustion engine (petrol) and one or more electric motors. They are combined with a traction battery that stores electrical energy.
