Pre-loading drivetrain to minimize electric vehicle rollback and increase drive responsiveness. In an exemplary embodiment, a method includes (a) detecting that an electric vehicle is stationary, a brake is engaged, and an accelerator is not engaged, and (b) controlling a vehicle motor to transition from a first mode to a second mode in response to (a). In the first mode, the motor is controlled to output torque in response to the accelerator position, and in the second mode, the motor is controlled to output torque sufficient to preload the electric vehicle. The method also includes (c) detecting the brake is transitioning away from being engaged and the accelerator is not engaged, and (d) controlling the motor to operate in a third mode in response to (c). In the third mode the motor is controlled to output torque sufficient to maintain the electric vehicle stationary.
