Asking whether a VW Tiguan II R 4MOTION DSG is a suitable car for families, is not easy to answer from a technical point of view. families have a wide range of requirements, so this consideration only considers the common aspects.
The VW Tiguan has 5 seats, which is enough for many families, and also brings a decent trunk with 1655 liters of volume, in which there is still room for luggage even with a stroller loaded. Good conditions for a family car. There are no Isofix brackets installed. These could be used to secure child seats easily and safely, via airbag deactivation, babies and small children could be carried along in corresponding seats against the direction of travel on the front passenger seat - however, this function is unfortunately not available on this vehicle.
