I dont know what you all heard or where you sourced this info. But when I saw it running on tuesday morning this week and it sounds like its roaring to me. Its probably not as loud because everything is brand new and its running smooth as butter. Its really down to how far away from it are you? You probably arent going to hear it from your hotel window. But the cars are definitely roaring all over that track. So get that outta your heads! Hulk is a big green machine!
