I honestly love it!!!! It's not loud in cabin and no drone whatsoever and any speed. When you get on the car it sounds great!!! My wife who I trust ( and knows more than half the guys on this forum about Audi's) approves and Says it's better than the Q5.
I may actually quiet down the Q5 not by choice, but I just found out we have out first baby on the way. Since the wife drives it it's her choice.
