The S6 limits the intrusion of engine noise into the cabin, and launches from a dead stop are sudden and authoritative, though necks are not snapped in the process. Around town or while cruising through congested traffic, occupants of the 2007 Audi S6 will be subjected to a stiff ride offset by firm yet immensely supportive sport seats. Higher speeds elicit a fair amount of road noise. We noticed that during the more casual sections of the drive, the throttle required some finesse when accelerating from a stop. On initial tip in, there was little response, with just a bit more pressure causing the powertrain to stir.
