Abstract
An electric drive for a motor vehicle comprising an electric motor and a drive unit is disclosed. The drive unit has a first gear stage, driveable by the electric motor, a second gear stage, driveable by the first gear stage, and a differential drive, driveable by the second gear stage. The first gear stage has a driving wheel and an output wheel, wherein the driving wheel is arranged coaxially to the output shaft of the electric motor and is rotatingly driveable by the electric motor around a first rotational axis A. The output wheel is drivingly connected to the driving wheel and is rotatingly driveable around a second rotational axis B, wherein the second rotational axis B is arranged parallel off-set to the first rotational axis A. The second gear stage and the differential drive are arranged coaxially to the second rotational axis B.
