To achieve our sustainability targets, we decided it would be best to match the car’s navigation system to the demands of electric driving. With the optional navigation system, all it takes is a quick glance at the dynamic range map to see which destinations you can reach. The system takes account of the remaining battery charge, your personal driving behaviour, the topography of your surroundings and real-time traffic information. This makes it highly accurate. If the battery is not sufficiently charged, the range assistant will suggest up to three other ways to reach your target destination safely. One of these could be simply switching to a more efficient driving mode. The system also shows you unoccupied charging stations where you can top up your BMW i3.
