The automobile (1) has an IC engine (2) and an electronic engine control (50), for controlling the engine revs and/or torque, with the output torque limited to a maximum value during idling revs and/or at low road speeds, e.g. by selective cut-out of the engine when the maximum permissible output torque is exceeded. L'invention concerne un véhicule automobile.Dans un véhicule automobile (1) comportant un moteur d'entraînement (2), une unité de commande (100) servant à commander la vitesse de rotation du moteur et/ ou le couple moteur du moteur d'entraînement, le couple moteur est limité à une valeur maximale pouvant être prédéterminée, notamment lors du fonctionnement de ralenti et/ ou lors d'une faible vitesse de déplacement du véhicule (1). Application notamment aux voitures de tourisme.
