1. A drive axle for a motor vehicle, the drive axle comprising:
first and second vehicle wheels;
a first shaft configured to drive the first vehicle wheel;
a second shaft configured to drive the second vehicle wheel;
a first electric motor having a first stator and a first rotor;
a differential gear configured to drive the first and second shafts, wherein, via the first and second shafts, the vehicle wheels are drivable by the first rotor of the first electric motor, wherein the differential gear has an input element permanently connected to the first rotor in a torque-transmitting manner so that drive torques provided from the first rotor are introduced into the differential gear;
a second electric motor having a second stator and a second rotor; and
a clutch,
wherein only one of the first and second shafts is assigned the clutch so that the one of the first and second shafts is connectable to the second rotor to conjointly rotate in a torque-transmitting manner while bypassing another one of the first and second shafts and the differential gear.
