Abstract

A drive assembly for a motor vehicle has a multi-step transmission and a differential drive. The multi-step transmission comprises a rotatingly drivable driveshaft and an intermediate shaft parallel to the driveshaft, and at least one first transmission stage and a second transmission stage for transmitting torque from the driveshaft to the intermediate shaft with different transmission ratios, as well as a shift unit, wherein the intermediate shaft comprises an output gear for transmitting torque to a differential carrier of the differential drive, wherein a rotational axis of the differential carrier extends parallel to the intermediate shaft, wherein the output gear and the shift unit are arranged axially between the at least two transmission stages, and wherein the driveshaft comprises bores for supplying lubricant.
