A powertrain includes an engine; a driveline including a gearbox having an input shaft connected to the engine, an output shaft to be connected to driving wheels of the vehicle and a countershaft for transmitting a rotation of the input shaft to the output shaft which can be coupled to the input shaft; an electric machine; a gear reduction mechanism having a free wheel and at least three separate and rotatable junction elements, the rotational speeds of the junction elements being interdependent but not having a fixed ratio relative to one another:a first junction element that is connected to the electric machine; a second junction element that is connectable to the free wheel; a third junction element that is connected to the countershaft. The torque ratio between the third junction element and the first junction element can be selected from at least two different ratios.
