Why does the Audi R8 have a V10 engine instead of a V8 engine?

I've noticed that the Audi R8 has a V10 engine, while other sports cars in its category have V8 engines. What is the reason behind this difference and how does it affect the performance of the car?

Having a V10 engine allows the Audi R8 to have a higher horsepower output and faster acceleration than a V8 engine. This gives the car a more powerful and thrilling driving experience.

Additionally, the V10 engine gives the Audi R8 a more distinct sound, which is part of its iconic appeal. The deeper growl of the engine can evoke more emotions and adds to the overall driving experience.
