Why does the Audi A7's engine produce a more aggressive growl compared to other cars?

I noticed that the Audi A7's engine has a distinct growl that is significantly louder and more aggressive compared to other cars. What makes the A7's engine different?

The Audi A7 is equipped with a performance exhaust system that amplifies the growl of the engine. This not only adds to the overall driving experience but also improves the engine's performance.

Audi has implemented a sound engineering technique called 'active noise control' to enhance the sound of the A7's engine. This technology uses speakers to create a more dynamic and theatrical engine noise.
