A hybrid vehicle, including first and second drive motors, an axle driven by the first and/or second drive motor, a mechanical transmission connecting the axle to the first and second drive motors. The transmission includes a planetary gear train having two reduction ratios between the second drive motor and the axle, and including a switching mechanism imposing each of the reduction ratios. The switching mechanism includes a first mechanism configured to rigidly connect and disconnect two components of the planetary gear train, and a second mechanism configured to halt and release a third component of the planetary gear train, the second mechanism is located on a portion of the transmission located between the planetary gear train and the first drive motor, the portion of the transmission is another planetary gear train, and the second mechanism is a coupling having two coupling states, including a state of blocking the other train.
