The A7 is a long, low hatchback, but it's also relatively wide. It's reasonably spacious, though rear-seat headroom suffers, especially with the available panoramic sunroof.
By the numbers, the A7 is a bit longer than many mid-size sedans, at 196 inches overall. It's lower, too, at about 55 inches tall--a height you'll find more often on sport-coupe spec sheets. As a result, all the A7's seating positions are fairly low, and entry and exit can be a little less easy than in the related A6 sedan.
The driving position can be tailored to fit a wide range of frames, but possibly 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.
Four adults still will fit in comfort in the A7, provided they're not too lanky. The highly adjustable leather seats in front won't leave anyone wanting; most models have heating and ventilation control too.
It's the back seat where smaller passengers will be welcome guests. The headliner's been scooped out to create more headroom, and the two bucket positions are pocketed, but overall head room is still on the lower side. There's a silly third flat high spot (not seat) reserved in the middle on the A7 only; we think it's there mostly for spec-sheet marketing.
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 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. Still, on turbodiesel models and the superpowerful S cars, there's more tire noise than on the all-season-shod A7 with the supercharged six.
