Why does the Audi R8 V10 return a higher top speed than the V8?

I am looking at the specifications for the Audi R8 and have noticed that the V10 version has a higher top speed than the V8. Why is this the case and what differences contribute to this?

The V10 engine in the Audi R8 has a larger displacement, producing more power and allowing for a higher top speed compared to the V8. Additionally, the V10 has a more aerodynamic design and improved handling, contributing to its higher top speed.

The V10 engine in the Audi R8 also has an upgraded exhaust system, which allows for better air flow and reduces back pressure, resulting in increased horsepower and a higher top speed.
