The Audi A4 doesn’t have quite as much rear space as the rival BMW 3 Series, but the difference is small and there’s enough room to accommodate a couple of six-footers. Access is pretty decent too, thanks to wide opening doors and low sills.
True, life isn't as comfortable for a central rear passenger, because there's a large transmission tunnel to straddle, but it's the same story in rivals.
Isofix child seat mounting on the outer two seats add to the practicality and the door bins will each swallow a 1.0-litre bottle of water. However, you’ll need to add the optional, and reasonably priced, Storage Pack if you want nets on the backs of the front seats and cupholders in the central armrest.
