The invention discloses a two-gear longitudinal front-drive hybrid power speed change system which comprises an engine, a motor assembly, an intermediate shaft assembly, a differential mechanism assembly and a switching device. The motor assembly comprises a driving motor arranged in the longitudinal direction of the engine, and the middle shaft assembly comprises a middle shaft extending in the longitudinal direction. The differential mechanism assembly comprises a differential mechanism shell, a main speed reduction driven gear arranged on the upper portion of the differential mechanism shell, a planetary gear shaft arranged in a differential mechanism, two planetary gears and two half axle gears meshed with the two planetary gears, and the main speed reduction driven gear is rotationally installed along the axis extending transversely and is in driving connection with the intermediate shaft; the planetary gear shaft is arranged in the differential mechanism in the longitudinal direction, the two planetary gears are fixed to the planetary gear shaft in the longitudinal direction at intervals, the two half axle gears are arranged in the transverse direction at intervals, and the switching device is used for switching the intermediate shaft to be in driving connection with one of the driving motor and the engine. The problems that the electric quantity of a longitudinally-arranged rear-drive hybrid vehicle is limited, and the axial installation space of a transversely-arranged front-drive vehicle is insufficient are solved.
