Are Diesel hybrids really environmentally friendly?

Hybrid vehicle technology, combining petrol or diesel thermal engine with an electric motor, is unquestionably a technological advance. However, we must not forget that a hybrid diesel vehicle, even if it is water, remains polluting. There are a multitude of parameters to consider in this race for fuel savings and automotive energy cleanliness.

Diesel hybrid and fine particulate matter

Although car manufacturers are technically able to design diesel vehicles that emit less CO2 than gasoline vehicles, the problem of fine particulate matter remains unresolved. Despite the filters that are supposed to limit the emission of fine particulate matter, the rates of release of these particles by diesel vehicles remain enormous and worrying. Fine particles are highly carcinogenic, and frail people are particularly affected by these airborne elements.

The Diesel hybrid, or the half-ecology

The  car fleet consists of 70% diesel vehicles. Diesel is a very popular fuel in France. It is taxed less than gasoline, and it allows for greater operating autonomy. Even if with 50 litres of diesel, you travel more kilometres than with 50 litres of petrol, ecologically it is a polluting fuel. The Diesel hybrid is therefore only half a solution.

Good to know: we can hope that with the tightening of European environmental standards and the technological advances of manufacturers, the diesel engines of tomorrow will be less polluting.
