Why does the Audi R8 need a V10 engine?

I've noticed that the Audi R8 comes with a V10 engine, while most other sports cars use V8 or even four-cylinder engines. What is the reasoning behind this choice and how does it affect the car's performance?

The V10 engine in the Audi R8 offers more power and torque, giving the car a better performance on the road. Additionally, the sound of a V10 engine is more exhilarating and adds to the overall driving experience.

A V10 engine allows for a better weight distribution in the car, resulting in improved handling and agility. This is especially important in a sports car like the Audi R8.
