Abstract: A front wheel driven, gas powered vehicle is converted to include a rear differential connected for power input to a first and second electrical motor, or a single electric motor if desired. When first and second electrical motors are used they are connected in parallel, the power input thereto being brought across a current limiting series of resistors to protect and control the current level thereto. A switching circuit connects in various series and parallel combinations a plurality of batteries and concurrently switches the necessary current limiting resistance. Thus a control combination is provided including a manual selector for the desired forward and reverse directions and the low and high current ranges which is further multiplied by the various resistances. In this configuration, the normally available gasoline power plant is retained in the vehicle and is augmented during periods of nonoptimal use by the above electric motor provisions.
