| 1. A vehicle (1) having a drive engine (5) arranged in a transverse direction of the vehicle, the drive engine (5) being drivingly coupled to a main gear box (6) and an output of the main gear box (6), in turn, being drivingly coupled to an input of a transmission unit (7), the transmission unit (7) facilitating variable distribution of supplied by the drive engine (5) to a first output shaft which supports a wheel (2A) and a second output shaft which supports a wheel (2B), the transmission unit (7) comprising a transmission input shaft (9) coupled to the main gear box (6) for supplying torque to the first and the second output shafts via first and second planetary gearsets (14, 15), an electric machine (16) being coupled to the first and second planetary gearsets (14, 15) via first and second interconnected shafts (14A, 15A) to facilitate variable distribution of the torque, delivered by the transmission input shaft (9), between the first and the second output shafts as a function of torque produced by the electric machine (16), and the electric machine (16) being actively connectable with the transmission unit (7), via a first shiftable clutch device (24) connected to a first end of the electric machine (16), and an opposite end of the electric machine (16) also being actively connectable with the drive engine (5), via a second shiftable clutch device (25), so that a degree of distribution of torque between the first and the second output shafts of the transmission device (7) is varied when the electric machine (16)is operating as a motor and also as a generator, and, when the electric machine (16) operates as a generator, the electric machine (16) is driven directly by the drive engine (5) and stores electrical power in a storage medium (26) electrically coupled to the electric machine (16).
