Summarizing Audi's unsympathetic approach to U.S. conditions, there's no single spot big enough to dump all your junk when you clamber aboard, disarrayed, distressed, disheveled and distracted as you head to work. Most vehicles have a big enough space in or near the center console to handle lots of debris, but not A6. Beyond feeling cramped, A6 also feels stiff. You'll notice most using the doors. They snap distinctly to each stop, instead of gliding smoothly from closed to open.
Seats feel too firm, almost hard, at least upon first sitting.
Some controls seem to be fighting or resisting instead of responding. A dominance freak would like the car's insistence on being overcome. Others might take a while to warm to it. The brake pedal offers another annoyance. Its spacing from the gas pedal is unusual, so you're apt to smack the side of the brake instead of hopping squarely onto it until you get used to the arrangement.
