Due to the environmental challenges and low emission regulations, research is going on Electric Vehicles (EV). The electric vehicle which is equipped with in-wheel motors also provides good control architecture. A variety of Electric Vehicle designs are being considered such as Rear Wheel Drive (RWD) EV, Front Wheel Drive (FWD) EV, Rear Wheel Drive with Steer-By-Wire System (SBW) and Four Wheel-Drive (4WD) with Steer-By-Wire (SBW) Systems. There is also another class of Electric Vehicle with Skid Steering /Differential Torque Driving Vehicle where differential torque is applied to the nonsteerable wheels for turning the vehicle. Adequate motion control algorithms that fulfill the driving control and safety criteria are being research for each kind of electric vehicle. However on the basis of different number of in-wheel motors each class of vehicle has its performance boundaries and limitations. In this paper we study the performance boundaries between the Four- Wheel-Drive with Steer-By-Wire Steering System and Rear-Wheel-Drive vehicle with Steer-By-Wire Steering System. All the simulations are carried out using TruckSim and results are reported in this paper.
