The real consumption of the BMW i8 depends entirely on personal patterns of usage. Due to the electrical drive components, individual driving behaviour has a higher influence on petrol consumption than is the case in conventional vehicles. With a fully charged battery, the maximum purely electrical range of 37 km can be fully utilised. If the eDrive button is activated, a purely electrical speed of up to 120 km/h is possible. In the driving modes COMFORT and ECO PRO, the petrol engine is automatically switched on by an intelligent operating strategy, and also for purposes of recharging the battery. In the SPORT mode, the petrol engine is running continuously. Depending on the type of driving and length of the route, this affects the consumption of the BMW i8 – the more often you charge the high-voltage battery by cable or Wallbox, the more you will be able to drive purely electrically and hence reduce the overall consumption.
