Whether a Audi A3 8Y Sportback 40 TFSI e S line S tronic is a good automobile for families, is not easy to answer from a technical point of view. The range of families requirements is wide, so this representation only considers the common aspects.
The Audi A3 brings 5 seats with it which is basically good and sufficient for many families, but the car fluffs when it comes to the trunk - 1100 liters of volume might not be sufficient for most families. There are no Isofix brackets installed. These could be used to secure child seats easily and safely.
