What is the different between Audi R8 V8 and V10 engine?

Can someone explain the main technical differences between the V8 and V10 engines used in the Audi R8 sports car?

The main difference between the V8 and V10 engines is the number of cylinders and displacement. The V8 has 8 cylinders while the V10 has 10, resulting in a bigger displacement for the V10 and more power output.

Another notable difference is the sound and character of the engines. The V8 has a more aggressive and raspy sound, while the V10 has a smoother and more refined sound.

In terms of performance, the V10 offers better acceleration and top speed compared to the V8. This is due to the higher power and torque output of the V10 engine.
