This paper investigates two most important points on velocity response and energy saving performance consisting of recovery energy and energy consumption of water hydraulic FST and PMT. The comparison between the experimental results of these two transmissions also will be presented in this research to get the conclusion for the advantages and disadvantages of each transmission. The PMT system has proved its many advantages such as reducing noise because of smooth operation; lengthening the life duration of the devices; and the drastic reducing of both steady state error in a working phase and energy consumption. The recovered energies of the both systems are almost same and get the values from 26.3 to 31.7% of the kinetic energy of flywheel
