Abstract
A drive device includes a drive machine, such as an electric motor, gear reduction planetary gear sets, and a differential. One of the gear reduction planetary gear sets utilizes multi-step planetary gears. The differential is a spur gear differential. To reduce axial length, one of the gearwheels of each multi-step planetary gears axially overlaps with planetary gears of the spur gear differential.
