1. A variable setting drivetrain for use with a vehicle, the variable setting drivetrain comprising:
an electric motor having an output shaft, wherein the output shaft generates an output torque having an output torque vector; and
a controller in operable communication with the electric motor and configured to output signals to the motor representative of a target output torque vector, wherein the controller includes:
a memory unit configured to store a first output map, a second output map, and a first user input therein, wherein the first output map is configured to determine a first torque vector in response to a current vehicle speed and a current vehicle direction, wherein the second output map is different than the first output map and is configured to determine a second torque vector in response to the current vehicle speed and the current vehicle direction, and wherein the first user selection input includes a first output map utilization percentage and a second output map utilization percentage, and
a processor in operable communication with the memory unit and the electric motor, wherein the processor is configured to determine the target output torque vector by calculating a weighted average of the first torque vector and the second torque vector.
