What is BMW M3's launch control system and how does it work?

I've heard that the BMW M3 has a launch control system, but I'm not sure what it does or how it works. Can you explain it to me?

The BMW M3's launch control system is a feature that helps optimize the car's acceleration from a standstill. By pressing a combination of buttons and pedals, you can activate the system and get the best possible launch performance.

To use the launch control system, first select the M Drive mode. Then, press and hold the DSC OFF button until the DSC and brake lights are illuminated on the dashboard. With your left foot on the brake and right foot on the accelerator, release the brake to start the launch control sequence.

It's important to note that using launch control too frequently can put a lot of strain on the car's drivetrain components. Make sure to allow the car to cool down between launches and avoid using it too often to prolong the life of your M3.
