1. A method of operating an electric vehicle, the method comprising:
receiving a restricted mode command to operate the electric vehicle in a restricted operating mode defining a restricted power output from a powertrain of the electric vehicle, the restricted power output being lower than a maximum power output available from the powertrain of the electric vehicle;
when the electric vehicle is in the restricted operating mode, receiving an operator propulsion command from an operator of the electric vehicle, the operator propulsion command being equal to or exceeding a propulsion command threshold;
commanding the powertrain of the electric vehicle to generate a first power output corresponding to the operator propulsion command, the first power output being lower than or equal to the restricted power output;
when the powertrain of the electric vehicle is generating the first power output, measuring an actual speed of the electric vehicle; and
when the operator propulsion command is equal to or exceeding the propulsion command threshold, the actual speed of the electric vehicle is below a speed threshold and the electric vehicle is in the restricted operating mode, commanding the powertrain of the electric vehicle to generate a second power output exceeding the restricted power output in response to the operator propulsion command.
