The powertrain has a main electric machine (12) connected to an axle shaft (24). A speed transmission device (36) comprises a primary transmission shaft (38) connected to a drive shaft (18) of a thermal engine (10) through a disengageable coupling (44), and carries a first large-diameter gear wheel (58) and a first small-diameter gear wheel (56) cooperating with a second large-diameter gear wheel (60) and a second small-diameter gear wheel (62) carried by a secondary transmission shaft (40) connected to the axle shaft. A primary shaft is connected to an auxiliary electric machine (14). The coupling is a centrifugal clutch. The thermal engine is an internal-combustion type thermal engine. The speed transmission device is a gearbox. The electric machines are used as current generators and electric motors.
