If it is true that the road of automotive evolution leads to electric propulsion, it seems equally true that we will travel it mainly on hybrid cars.

Arrived on the market over twenty years ago, the solution that combines internal combustion engine (petrol or diesel) and electric motor was born above all to reduce consumption. In more recent times, characterized by the non-stop fight against CO2 pollution, the hybrid is an ideal solution to reduce emissions, pending the transition towards full-electric mobility. There are three main solutions: Mild-Hybrid, full-hybrid and Plug-In Hybrid. Each with its pros and cons.

Mild Hybrid

With the Mild Hybrid (MhEV), the system provides that a small electric motor connected to the thermal engine supports the latter at ignition, at low speeds, and in acceleration. The system works using an additional 12, 22.5 or 48 Volt electrical system and recovers energy during braking by charging a small battery.

Pro: this solution characterized by reduced dimensions and weights, as well as by lower complexity compared to the traditional full-hybrid. Used both for small cars, and for medium and large cars, it reduces consumption and emissions, costs less than other hybrids but maintains the advantages such as access to limited traffic areas, exemption from stamp duty or parking free in the blue stripes.

Versus: Mild Hybrid never travel with zero emissions. The result is less green driving compared to other systems with a slightly higher price than traditional engines.

Full-Hybrid

In Full-Hybrid (hEV), the electric motor connected to the wheels and can work alone by moving the car for a few kilometers, or more often paired with the thermal engine. The battery is recharged by the latter and by the energy generated during braking.

Pro: the system allows a greater reduction in fuel consumption and emissions and is the ideal solution for those who travel a lot in the city, where stop & go and reduced speeds are frequent. Obviously it enjoys all the advantages reserved for hybrid cars, including incentives.

Versus: The more complex system, weighs more (also due to the larger battery) and the difference in price with equivalent performance thermal engine vehicles rises.

Plug-In Hybrid

Finally, the Plug-In Hybrid (PhEV), the last step before the only electric propulsion, a hybrid with a more powerful engine and battery, equipped with a recharge socket, which can travel in full-electric mode in the city for quite long stretches.

Pro: The possibility of traveling between 50 and 60 km with zero emissions added to the autonomy of the heat engine. The arrival in the coming months of many new models to expand the choice.

Versus: the weight and operating complexity are greater than other hybrid solutions, as well as the purchase cost even in the presence of incentives. Then there is the need to install a wallbox for charging in the garage and to use the (still few) columns in the area.
