Claim 0:
1. A drive system for an electric vehicle, comprising:
a front wheel electric motor (EMF) and a rear wheel electric motor (EMR) of the same specification;
a front wheel reducer (GF) whose output shaft is operatively coupled to a front wheel drive axle (SF) of the electric vehicle via the front wheel electric motor (EMF); and
a rear wheel reducer (GR) whose output shaft is operatively coupled to a rear wheel drive axle (SR) of the electric vehicle via the rear wheel electric motor (EMR), wherein the front wheel reducer (GF) has a transmission ratio different than that of the rear wheel electric motor (EMR);
wherein the transmission ratio (rF) of the front wheel reducer (GF) is less than the transmission ratio (rR) of the rear wheel reducer (GR), thereby minimizing torque output waste.
