1. A launch control system for a vehicle having a powertrain, the launch control system comprising:
a driver interface configured to display information to and receive input from a driver of the vehicle, the driver interface comprising a brake pedal, an accelerator pedal, and two paddle shifters; and
a controller in communication with the driver interface and configured to:
obtain a desired launch torque curve and a desired launch speed;
perform a pre-staging procedure including generating a torque reserve for the powertrain, in response to (i) the brake pedal being fully engaged, (ii) the paddle shifters being a first configuration, and (iii) the accelerator pedal being at wide-open throttle (WOT), wherein the pre-staging procedure is performed by the vehicle in a pit area of a drag race facility in preparation for a drag race;
after the pre-staging procedure is complete, control vehicle positioning/movement in response to driver manipulation of the brake pedal;
perform a staging procedure including (a) increasing the torque reserve, (b) activating a trans brake feature to hold the vehicle stationary, and (c) increasing a speed of the powertrain to the desired launch speed, in response to (i) the paddle shifters in a different second configuration and (ii) fully releasing the brake pedal; and
after the staging procedure and in response to the paddle shifters being in a different third configuration, executing a vehicle launch procedure by depleting the torque reserve according to the desired launch torque curve.
