Granatiere was powered by two Belluzzo geared steam turbines, each driving one propeller shaft using steam supplied by three Yarrow boilers.[4] Designed for a maximum output of 48000shp and a speed of 34kn35kn in service, the Soldati-class ships reached speeds of 39- during their sea trials while lightly loaded. They carried enough fuel oil to give them a range of 2340nmi at a speed of and at a speed of .[3]
