The present is a powertrain for an automotive vehicle comprising a thermal engine (10), a speed variation device (14) including an engine epicyclic gear train (26) with a sun gear (36) and a crown (50), each connected to shaft (12) of thermal engine (10) by a controlled clutch (28, 30, 30′) and to a fixed part (46) of the vehicle by a one-way coupling (32, 34). A machine epicyclic gear train (90) is arranged on a machine shaft (92) which is substantially parallel to engine shaft (12) and connecting engine epicyclic gear train (26) to a track (126, 128) for motion transmission to a drive axle (16). The machine epicyclic gear train comprises a sun gear (104) carried by a sun gear shaft (110), a crown (112) and a planet gear carrier (94). Speed variation device (14) comprises an engine toothed wheel (150) carried by engine shaft (12) which connects the shaft to a machine toothed wheel (152, 176) carried by sun gear shaft (110).
