A specific cyclic range is indicated for every BMW iPerformance model. The electric range actually achieved depends on many factors. Important influences are the air-conditioning and heating demand, the general load on the on-board power system (e.g. navigation, radio, seat and windscreen heating, climatic conditions in summer and winter) as well as individual driving style.
When the high-voltage battery is discharged, purely electric driving is no longer possible, but it is still possible to continue driving perfectly as normal thanks to the combustion engine. An intelligent energy management system means no damage can occur to the high-voltage battery at any time even it is displayed as completely “empty”.
