Why do the Audi R8 models have a mid-engine layout?

I've noticed that all Audi R8 models have their engines positioned in the middle of the car. Why did Audi choose this layout and how does it enhance the car's performance?

The mid-engine layout allows for better weight distribution in the car, resulting in improved handling and balance. Additionally, it allows for a lower center of gravity which enhances stability and agility on the road.

A mid-engine layout also creates a more powerful and responsive acceleration, as the weight of the engine is directly above the driven wheels. This gives the Audi R8 models a thrill-inducing and exhilarating driving experience.
