Why is the Audi R8 V10 so much faster than the V8?

I've noticed a significant performance difference between the V8 and V10 versions of the Audi R8. Can someone explain why the V10 is so much faster?

The Audi R8 V10 has a larger engine and more horsepower compared to the V8. This means it can accelerate faster and reach higher speeds.

The V10 also has a better power-to-weight ratio, which contributes to its faster performance.

Additionally, the V10 engine has a higher redline and a more aggressive engine tune, giving it a more race-oriented feel.
