A drive device has two electric drive machines for distributing the torque between two wheels of an axle of a motor vehicle and an inverter unit which is electrically connected to the drive machines for converting an electrical DC signal into a drive-machine-specific electrical AC signal. The two drive machines are arranged spaced apart from one another in the axial direction to form an intermediate space, and components of the inverter unit are arranged in a first area, located in the intermediate space and oriented in a first direction transversely with respect to the axial direction, of the drive device, and in a second area, adjoining the intermediate space and oriented parallel to the axial direction, of the drive device, to form a low-inductance, T-shaped inverter architecture.

A coolant circuit has an engine cooling circuit in which coolant can be circulated in order to cool an internal combustion engine via a cylinder head cooling circuit and a crankcase cooling circuit separated from the cylinder head cooling circuit. The coolant circuit includes a transmission cooling circuit for cooling a transmission, the transmission cooling circuit branching off from the engine cooling circuit. A valve is arranged in the transmission cooling circuit. A controller is designed to open and close the valve depending on an operating state of the internal combustion engine and/or the transmission. In particular, the transmission cooling circuit branches off from the crankcase cooling circuit to a section along which the crankcase cooling circuit is separated from the cylinder head cooling circuit.
