More and more manufacturers are offering their hybrid cars. It must be said that the mode of operation of these vehicles makes it possible to reduce CO emissions.2. Here’s how it works.Hybrid cars are growing in popularity with many manufacturers now offering this type of vehicle. Their efficient mode of operation significantly reduces CO2 emissions. Find out how a hybrid car works.
A hybrid car uses two sources ofenergyenergy different. The idea of combining, on board the same vehicle, an electric motor and a thermal motorthermal motor seems to be an interesting solution.
Advantages of the hybrid car
This makes it possible to maintain an excellent level of dynamic performance while significantly reducing pollution in urban areas (thanks to optimized energy management). Finally, the hybrid carhybrid car benefits from the advantages of both propulsion systems:
- silence and cleanliness for electric propulsion;
- power and autonomy for the internal combustion engine.
How a hybrid car works
A hybrid vehicle is equipped with a heat engine which has a generally electrochemical energy storage system. This allows it to storekinetic energykinetic energy during decelerations, but also the excess energy produced in certain driving situations.
This engine always remains in an optimal operating zone, to avoid fuel consumption peaks, and, when the power required at time t is too low, the energy produced in excess is stored to be remobilized later .

Several levels of hybridization
Vehicles available on the market present levels ofhybridizationhybridization variables :
- Microhybridization simply makes it possible to take over from the heat engine in order to ensure power to electrical devices. It ensures a reduction in consumption of around 5%. It is adopted by a large majority of manufacturers. The German BMW was the first to generalize this technology.
- Light hybridization (semi hybridsemi hybrid), for its part, is actually based on a battery of several hundred watt hours and allows savings of 10 to 30% on urban journeys.
- Complete hybridization (full hybridefull hybride) — this is the example of the classic Toyota Prius or the Ford Mondeo Hybrid — allows the car to operate from its stored energy reserve alone. The reduction in consumption can be up to 50%.
- Plug-in hybrids – for example the Volkswagen Passat GTE, the Audi A3 e-tron or the Mercedes C-Class 350e – finally, can drive for several tens of kilometers like real electric vehicles.
Series, parallel or power bypass hybrids
Two main hybridization solutions can be proposed:
- So-called “series” hybrids are rather rare. Here, the heat engine works like a generator, to produce the electricity necessary for the electric motor to move the car.
- So-called “parallel” hybrids are the most common. In this case, the two engines are able to propel the car separately.
Power bypass hybrids combine the two previous solutions. Here, 100% electric propulsion is possible, but part of the power of the thermal engine is always transformed into electricity, either to recharge the battery or to directly power the electric motor.
