What is the purpose of Launch Control in the Audi R8 and how can it be accessed?

I've heard about Launch Control in the Audi R8, but I'm not sure what it does or how to use it. Can someone provide some details on its purpose and how to activate it?

Launch Control is a feature in the Audi R8 that allows for optimal acceleration and performance off the line. It is typically accessed by pressing and holding the ESP button, then pressing the throttle down to the floor. Hold it there until the RPM reaches a certain point and then release. It takes practice to get it right, but once you do, the feeling is exhilarating.

In simple terms, Launch Control ensures that the engine revs to its optimal range and the power is delivered evenly to all four wheels, resulting in a quick and smooth launch. To activate Launch Control, put the car in Sport mode, hold down the brake pedal, then press the gas pedal all the way down. When you release the brake, the car will launch with maximum performance.
