Why do Audi R8 engines have a unique firing order?

I have noticed that the Audi R8 has a different firing order than other V8 engines. What is the reason behind this?

The Audi R8 engine has a unique firing order to improve power delivery and minimize vibration. The firing order of 1-5-4-8-6-3-7-2 ensures that the firing intervals are evenly distributed, resulting in smoother and more efficient engine performance.

The firing order of the Audi R8 engine is designed to enhance the engine's sound and exhaust note. 1-5-4-8-6-3-7-2 is a non-conventional, '1-5-4' start produces a distinct uneven firing sound, giving the car its signature engine sound.
