A hybrid powertrain unit comprises an internal-combustion engine (E), and a gearbox device (C) with a primary shaft (3) that can be connected to the shaft (5) of the internal-combustion engine (E) via a clutch device (6). The gearbox device (C) comprises a secondary shaft (7) with an output pinion (9) meshing with a first crown wheel (10) of a differential (D), the casing (11) of which is rigidly connected to the casing (2) of the gearbox device (C). The unit further comprises an electric machine (M) adapted to function both as electric motor and as electric generator, having a shaft (16) connected by means of a transmission to a second crown wheel (19) of the differential (D). In the connecting transmission, arranged between the shaft (16) of the electric machine (M) and the second crown wheel (19) of the differential (D) is an engagement device (25) that can be driven via an electronic-control actuator. The shaft (16) of the electric machine (M) is connected to the shaft (5) of the internal-combustion engine (E), on the side opposite to the gearbox device by means of a belt transmission that controls auxiliary devices (CO, VS) of the motor vehicle, which are mounted coaxially with respect to the electric machine.
