Why is there a distinct engine note in Audi cars?

I've noticed that Audi cars have a unique engine sound compared to other brands. Is there a specific reason for this?

The distinct engine note in Audi cars is due to their use of unique engine technologies such as TFSI (Turbo Fuel Stratified Injection) and TDI (Turbo Direct Injection). These technologies enhance the performance and efficiency of the engine, resulting in a distinct sound.

Audi's engineering team puts a lot of effort into designing and tuning the engine to create a distinct sound that reflects the brand's performance and power. This unique engine note is a result of precise engineering and careful calibration.
