An electric utility vehicle with a frame, at least one drive motor mounted to the frame through a suspension assembly, a wheel mounted to the motor, and a steering assembly for steering the vehicle, wherein the steering assembly may be interchangeably reconfigured into a side driver configuration and a center driver configuration. The drive motor may be mounted at any one of four wheel positions. The suspension assembly may be interchangeably reconfigured as an independent A-arm suspension assembly and a trailing arm suspension assembly. The vehicle may include a controller coupled to the motor for independently supplying electrical power to each of two drive motors, such that during a turn an outside motor is supplied with more power than an inside motor. The controller may supply electrical power the drive motor according to a selected acceleration profile of at least two acceleration profiles.
