A drive device for a motor vehicle includes at least one electric machine having at least one rotor element which is configured to delimit an installation area in a radial direction. At least one transmission device is disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element. A fluid supply device having at least one fluid channel is provided for supply of fluid to at least one cooling or lubrication point of the drive device. The fluid channel has a first part area running in a stationary first component, and a second part area which adjoins the first part area in a flow direction of the fluid through the fluid channel and runs in a second component of the drive device. The second component is supported for rotation about an axis of rotation in relation to the first component.

A drive device for a vehicle includes at least one electric machine having at least one rotor element which is configured to delimit an installation area in a radial direction, and an active rotor part which is operably connected to the rotor element and has a ring structure to guide a magnetic flux of the electric machine. At least one transmission device is disposed, at least partly, in the installation area and configured to be driven by the electric machine via the rotor element.
