Sorry za offtop ale...
Nie wiedziałem że w TT jest system podkręcający dźwięk silnika :

"The system is designed such that the sound becomes meatier when the
driver demands more power from the engine. [...] The pressure pulsations which during the gas exchange cycle are transmitted to the membranes in the sound
generator, where they are amplified by the sound generator and relayed to the vehicle interior. "
