The invention elates to an electric drive assembly for a multi-axle driven motor vehicle which comprises an internal combustion engine, a multi-step transmission with an output shaft for driving a rear axle, as well as an optionally driveable front axle. The drive assembly comprises an electric machine (6), a reduction gearing (7) drivingly connected to the electric machine (6), a driveshaft (9) drivingly connected to the reduction gearing (7) and drivingly connectable to a front propeller shaft (65) for driving the front axle, and a housing 5 in which the electric machine (6) and the reduction gearing (7) are arranged. The housing (5) comprises connecting means (16) for connecting the drive assembly (2) to the multi-step transmission. The electric drive assembly is designed such that, with the electric drive assembly mounted at the multi-step transmission (56), a rear propeller shaft (57) can be connected at least indirectly to the output shaft of the multi-step transmission for driving the rear axle. Furthermore, the invention relates to a motor vehicle with such a driveline assembly.
