@MenorcaMike Both models, i3 and i3S, are now the same advance payment starting at £1499 (PIP/DLA) or £371 (WPMS). The output of the charging points in shopping centres varies enormously from 3kW to over 50Kw. The free to use ones are generally 3kW or 7kW, so for each hour the car was parked, they would add approximately 3kWh or 7kWh to the 40kWh useable capacity of the i3 battery. The range quoted by BMW is 182-188 miles and may not reflect real life driving results which depend on a number of factors including the starting charge of the battery, accessories fitted (post registration), variations in weather, driving styles and vehicle load. Users are quoting real world figures of 150-200 miles to a full charge. In essence the range is determined in similar way to a petrol or diesel car, it all depends on how it is driven.
