What is Acceleration Squat in Audi R8?

I've heard about Acceleration Squat in Audi R8, but I'm not sure what it actually means. Can someone explain it to me?

Acceleration Squat is a term used to describe the action of the front end of the car lifting up during hard acceleration. This can improve the weight distribution of the car and provide better traction.

Acceleration Squat is a feature in Audi R8 that utilizes the car's suspension to lower the rear end during hard acceleration, resulting in better weight transfer and increased stability.
