Abstract: The present hybrid drive is especially suitable for buses and the like which must make frequent stops. The engine, clutch, and automatic transmission are arranged in series. A flywheel energy storing device is coupled to the drive train by a further clutch. The automatic transmission is a power distribution transmission including a mechanical power transmission branch and a hydraulic power transmission branch. An auxiliary power take-off connects the flywheel to the drive train. The auxiliary power take-off is arranged laterally adjacent to the transmission. The connection point between the transmission and the auxiliary drive is constructed to take up power which, in addition to the engine power, is re-circulating through the hydraulic branch and which flows into the mechanical branch.
