comment j'ai décodé la P3 ???? 
. Je corrige le post. Mes L/100, c'était la moyenne sur tout le trajet. Elle ne doit pas bouger si ni les L ni les km ne bougent. Je pense que tu parles de défilement de la consommation instantanée, hautement instable et sans intérêt sur la Prius, qui accumule de l'énergie dans la batterie HV. As-tu fait un typo : 5 mn, au lieu de quelques secondes (5 ?).
