A launch control system which maximizes hybrid vehicle acceleration from a standing start. A hybrid vehicle includes wheels, an engine, a motor-generator, a processor, and an actuation device. The processor controls an engine speed and an engine torque independently from a wheel speed and a wheel torque. While the hybrid vehicle is at a standstill, the actuation device is switched to an on state, and the engine speed and engine torque is raised to optimal values. When the actuation device is subsequently switched to an off state, the engine speed and the engine torque is applied to the plurality of wheels to launch the hybrid vehicle. The processor blends or further adjusts the torque applied to the plurality of wheels to maximize the acceleration while optimizing an amount of wheel slip. The processor then learns the launch to improve performance on subsequent launches.
