* Maximum power determined in accordance with UN GTR.21; up to 25 kW of this is accounted for by the overboost, which can be called up for max. 30 seconds. The power output available in individual driving situations depends on variable factors such as ambient temperature, charging/temperature/conditioning status or physical ageing of the high-voltage battery.In particular, for the maximum power (overboost) to be available a high-voltage battery temperature between 23 and 50°C and a battery charge level > 88% are required. Any deviations from the parameters specified above in particular can lead to reduced power output and even to the overboost not being available at all. To a certain extent, the battery temperature can be indirectly influenced via the auxiliary air conditioning function and the charge level and other parameters can be set in the vehicle. The power output currently available is displayed on the vehicle’s power meter. To maintain the high-voltage battery’s usable capacity as far as possible, it is recommended to set a charging target of 80% for the battery for day-to-day use (can be adjusted to 100% e.g. before long journeys).
