1. An assembly for an electric vehicle including a first and second set of wheels, said assembly comprising;
an input shaft extending along a first axis;
an electric motor rotatably coupled to said input shaft, co-axially aligned with said first axis, and configured to provide rotational torque to said input shaft;
an intermediate input shaft extending along a second axis different from said first axis, with said intermediate input shaft being rotatably coupled to said input shaft and configured to receive rotational torque from said input shaft;
an output shaft extending along said second axis and spaced from said intermediate input shaft along said second axis;
a planetary gearset rotatably coupled to said intermediate input shaft and said output shaft, with said planetary gearset co-axially aligned with said second axis and configured to transmit rotational torque from said intermediate input shaft to said output shaft; and
a final drive co-axially aligned with said first axis and rotatably coupled to said output shaft for providing rotational torque to at least one of the first and second set of wheels of the electric vehicle;
wherein said planetary gearset comprises a sun gear rotatably coupled to said intermediate input shaft, a planet gear coupled to said sun gear, a ring gear coupled to said planet gear such that said planet gear is disposed radially between said sun gear and said ring gear, and a planet carrier coupled to said planet gear and rotatably coupled to said output shaft.
