Disclosed is a drive unit for a drive axle of a vehicle having a first and second electric machines, a differential and a transmission with first and a second transmission input shafts, a transmission output shaft, at least a first planetary gearset. A first shifting unit has three shift positions. In a first shift position, a second element is connected to a rotationally fixed component. In a second shift position two of the three elements of the first planetary gearset are connected rotationally fixed to one another. A second shifting unit has exactly three shift positions. In a first shift position a first transmission input shaft and a second transmission input shaft are connected rotationally fixed to one another. In a second shift position the second transmission input shaft is connected at least indirectly to the second element of the first planetary gearset.
