Titre : Does the thermal propulsion live its last hours, for an all electric? Auteurs : Cornel Stan, Philippe Guibert, Revue : Entropy: Thermodynamics – Energy – Environment – Economy Numéro : Issue 3 Volume : 1 Date : 2021/02/8 DOI : 10.21494/ISTE.OP.2021.0616 ISSN : 2634-1476 Résumé : Reducing greenhouse gas emissions is an urgent matter and rethinking the world’s vehicle fleet must be done with the utmost care because there will not be a second chance. All-electric vehicles, the attractiveness of the "new mobility" formula and proposals for new uses are obvious. Electric vehicles have the merit of helping to reduce pollution in our cities. However, they cannot be considered zero-emission vehicles. As for the thermal vehicle, it has certainly not exhausted its margins for improvement. It should see its energy efficiency almost double by 2035 while reducing CO2 and pollutant emissions. This paper presents a global reflection on the possible strategies to adopt.
