At first glance, the 2013 Audi A7 and S7 Sportback models (which have nearly identical interior accommodations) look long and wide, but their low, sleek body style makes it a bit hard to size up next to sedans. By the numbers, the A7 is a little longer (196 inches) than today's typical U.S. mid-size sedans; and while it's relatively wide, its low 55-inch-tall roofline really does put it at a height with some sport coupes.
What that means is that the seating position is relatively low, and that getting in and out is by no means like some other odd new designs such as the Acura ZDX (that's more of a utility vehicle). Provided you don't have too many lanky passengers in the A7, there's enough space for four adults to get comfortable, while up front the comfort is almost without bounds thanks to highly adjustable seats.
In back, there are basically two separate bucket seats. From the backseat, you might notice that the headliner has been carved out to accommodate taller adults; if you're one of those, you'll fit but might find it unsettling.
One thing bothered us a bit: Perhaps because of side-impact crash requirements, the driver's seat isn't centered on the steering wheel. It's not a big deal though, as the low-set instrument panel is canted slightly toward the driver, pushing forward organically at the corners to enhance a feeling of spaciousness.
The A7's cargo space is definitely better than that of a typical sport coupe, though you will need to watch the hatch glass when closing it. Rear seatbacks fold forward to expand the space, which is a little shallow if you're sizing this up by utility or wagon standards but far more flexible than a sedan's trunk.
Audi also painstakingly worked to minimize minor vibrations from the engine or the road surface, and the A7's suspension components and subframes are isolated with hydraulic dampers. That pays dividends in keeping the interior quiet. An integrated spoiler extends at 80 mph for high-speed aerodynamics and retracts again at 50 mph, while frameless doors—a feature that's typically the domain of coupes and convertibles—have a complex sealing system that helps keep the side profile smooth and noise-free.
