Miracle solution for some, false good idea for others, the electric car is now fueling heated debate. In fact, with no historical hindsight, it is very difficult for now to have a definitive opinion on this technology.

We are therefore reduced to listen to the speeches of the builders, who believe almost all the virtues of the electric. It is also possible to peel the scientific studies, and that of the Massachusetts Institute of Technology (MIT ) is currently making a lot of noise. Indeed, it indicates that finally, a Tesla Model S pollutes more than a Mitsubishi Mirage petrol.

The researchers studied the impact of a car on the environment throughout its life (production, use and finally recycling). Conclusion, taking into account all these parameters, a Tesla Model S emits on average 226 grams of CO2 per km, against 192 grams for the Mitsubishi Mirage. The BMW 750i xDrive, also tested in this study, is less good than the Model S, with an average of 385 grams. As a reminder, it is equipped with an eight-cylinder gasoline 450 hp.

Importantly, the work was done in the United States, in the Midwest, a region where electricity sometimes comes from fossil fuels. This partly explains the mixed results of the Model S . The results would probably be different elsewhere, but the nuclear does not pollute it too?

It is difficult to rule on the objectivity of a study, whether for or against something. This could probably be contradicted by other works done differently. But anyway, she points to a problem that does exist, that of the ecological impact of electricity (extraction of lithium and cobalt, recycling batteries, etc.), too often underestimated . Today, manufacturers such as Renault and BMW are seeking to limit it by offering a second life to used batteries .
