What is the difference between a V8 and a V10 engine in an Audi R8?

I'm confused about the different engine options for the Audi R8. Can someone explain the technical differences between a V8 and a V10 in this car?

The main difference between the V8 and V10 engine in the Audi R8 lies in their cylinder configurations. The V8 has 8 cylinders arranged in a V shape, while the V10 has 10 cylinders arranged in the same V shape.

Another significant difference is the power output. The V8 engine in the Audi R8 produces 540 horsepower whereas the V10 engine produces 620 horsepower, making it more powerful and faster.

The V10 engine also has a different sound and exhaust note compared to the V8. It has a more aggressive and higher-pitched engine sound, giving a more thrilling driving experience.
