What is the launch control feature in Audi R8?

I've heard a lot about the launch control feature in Audi R8 but can't seem to find it in my car. Can anyone enlighten me on how I can use this feature and what benefits it offers?

The launch control feature in Audi R8 allows for a perfect launch off the line, giving you maximum acceleration and performance. It's activated by putting your car in sport mode and then holding down the brake and accelerator simultaneously. Keep in mind that this feature is only recommended for track use.

I highly recommend using the launch control feature sparingly as it puts added strain on your car's engine and transmission. While it's tempting to use it every time you take off, consider using it only at the track for optimal performance and to prolong the lifespan of your car.
