1 Doctor owner from new with a full BMW service history. This BMW i3 also comes with a high level of optional extras. According to most reviews, the best range you can expect from a BMW i3 is around 160 miles in real-world driving conditions, with the official figures claiming slightly higher ranges depending on the model and driving style; the "i3s" variant may have a slightly reduced range compared to the standard i3, but still around the 160 mile mark.
