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 (48) which are each connected to shaft (12) of the thermal engine by a controlled coupling (28, 30) and to a fixed part (46) of the vehicle by a one-way automatic coupling (32, 34). A machine epicyclic gear train (90) is arranged on a machine shaft (92) substantially parallel to engine shaft (12) and connects the epicyclic gear train to a track for motion transmission to a drive axle. The machine epicyclic gear train comprises a sun gear (94) carried by a sun gear shaft (100), a crown (126) and a planet gear carrier (108). A speed variation device (14) comprises an additional epicyclic gear train (138) and an engine toothed wheel (168) carried by the shaft (12) and connects the shaft to a machine toothed wheel carried by additional epicyclic gear train.
