An electric drive module and a method for switching a drive module between a torque vectoring and at least one propulsion mode are provided. A controller can switch the drive module to the torque vectoring mode when a first set of conditions is met and can switch to one of the propulsion modes when either a second or a third set of conditions is met. The first set can include: torque requested by an operator is less than or equal to a first demand threshold; and a vehicle velocity is greater than or equal to a first velocity threshold. The second set can include: the vehicle velocity is less than a second velocity threshold; and a vehicle lateral instability is less than or equal to an instability threshold. The third set can include: the torque requested by the operator of the vehicle is greater than a second demand threshold.
