Asking whether a BMW i3 I01 s (120 Ah) Edition RoadStyle is a useful 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 BMW i3 has only 4 seats and is therefore ruled out as a family car from the outset. The trunk is also very tight with a volume of 1100 liters is very tight. There are no Isofix brackets installed. These could be used to secure child seats easily and safely, if a little more space is needed in the interior, the rear seat can be folded down.
Rating: The BMW i3 is due to the small number of seats (4), small trunk volume (1100 liters) regardless of other features, it is not suitable for families.
