There’s more than enough leg and shoulder room for a couple of tall adults up front and, as long as you steer clear of the optional sunroof, even those well over six feet tall aren’t likely to complain about head room, either.
The simple dashboard design doesn’t conceal a huge number of cubbyholes, but there are storage areas ahead of the gearlever and under the central armrest, plus a couple of cupholders beneath the air-con controls. The door pockets on either side are each big enough for a large water bottle, too.
As long as you’re only carrying a couple of adults in the back, even six-footers should be reasonably happy with the amount of leg and head room available. If you need a car with greater rear seat space then the Skoda Octavia or Ford Focus are the models to look at. The Octavia is certainly more comfortable for three adults in the back, and in this respect the narrower A3 compares more closely with the Mercedes A-Class. The A3 is far better in the rear than the pokey BMW 1 Series, though.
There isn't much stowage space in the back for odds and ends, although the door pockets are each big enough to hold a small drinks bottle.
Seat folding and flexibility
The A3’s rear seats aren’t especially innovative. They don’t move back and forth to set a balance between passenger and boot space, for instance (that's mainly the preserve of SUVs). The seatbacks do split 60/40, or, for a relatively small premium, you can choose a more flexible 40/20/20 arrangement.
Unlike some of its rivals (the Octavia being one), the A3 isn't available with a folding front passenger seat that allows you to carry really long items, such as ladders. It does get height adjustment as standard, but adjustable lumbar support costs extra.
The Audi A3’s boot has almost exactly the same amount of space as the Mercedes A-Class, so unsurprisingly, both can fit up to six carry-on suitcases. While that’s pretty decent for the class, it's miles away from the class champion Skoda Octavia, which can take eleven. It’s also worth noting that quattro four-wheel-drive models suffer a 40-litre reduction in boot space because of the extra oily bits underneath.
An adjustable boot floor comes as standard, which can be raised to reduce the load lip at the boot's entrance. It also ensures there’s no step up to the rear seats when they’re folded down. The folded seats don’t lie totally flat but the slope is a small one, so it shouldn’t cause too many loading dramas. The boot opening is a decent size and shape, too.
