Si on regarde la concurrence, par exemple l’électricité, il y a des rendements de conversion, la charge/décharge, la production électrique etc etc, on n’a pas des rendements excellents non plus de primaire vers roue !

Le rendement maximum est pour les moteurs automobiles modernes, de 35 % environ pour les moteurs à allumage et de 45 % pour les moteurs Diesel. Les plus gros moteurs industriels dépassent 50 %.

Dans le cas d’un moteur automobile qui fonctionne rarement à forte charge et de manière toujours transitoire, le rendement réel pratique est beaucoup plus faible. Pour rouler à vitesse stabilisée à 120 km/h, la majorité des voitures n’a guère besoin de plus de 25 ch, alors que les moteurs peuvent souvent en fournir quatre à huit fois plus, ce qui conduit à un rendement pratique très dégradé. Du fait des pertes complémentaires liées à la transmission, aux accessoires tels que la direction assistée et la climatisation, aux périodes d’arrêt, le rendement réel pratique d’une voiture ne dépasse guère 12%.
