1. A drive train for a motor vehicle, comprising:
an electrical machine including a rotor;
a transmission including a drive shaft coupled to the rotor of the electrical machine, the transmission having a fixed gear ratio to transmit rotation from the drive shaft to a power takeoff shaft and the transmission being configured such that the drive shaft and the power takeoff shaft are configured to rotate at different rotational speeds when both the drive shaft and the power takeoff shaft are in motion; and
a coupling device which is adapted to couple the drive shaft of the transmission to the power takeoff shaft of the transmission to block a rotation of the power takeoff shaft.
