Asking whether a BMW i3 I01 (94 Ah) is a good family car, 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 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.
