The A4 Avant might not be able to match the voluminous space you’ll find in the back of a Passat Estate, but it compares pretty well with rivals such as the BMW 3 Series Touring and Mercedes-Benz C-Class Estate by offering a wider interior than both. Access is pretty decent, too, thanks to wide opening doors and low sills.
There’s enough rear leg and head room to suit those of above average height, but if you are taller than six feet, you may feel the top of your head brushing the rooflining. This is more of an issue if you’re the third passenger in the middle seat, in which case you’ll also need to contend with the raised central tunnel that limits foot space.
The A4 Avant is practical in other respects, with Isofix fittings on the outer two seats for a child seat and rear climate control fitted as standard to all models.
Storage options are a little thin on the ground, but you do get a couple of cupholders contained in the fold-down rear armrest and the door bins will each take a 1.0-litre bottle of water.
