Good morning, yes that is correct. The tests at that time were all carried out in warm summer temperatures. In the meantime, I have already noticed the following: the battery does not become completely empty in cold outside temperatures, there is a stored minimum charge level. Exact values are not documented, but here is a guide. From approx. 25°C the battery is discharged to 0%, between 10-25°C the minimum charge level is approx. 10%, below 10°C the minimum charge level is 20%. => This means that below approx. 25° generally only 90% capacity is available and the 63 km range can then no longer be achieved. Converted with a 10% minimum state of charge, 63 km would currently be a range of approx. 56 km. And at under 10°C with 20% minimum state of charge, it would then have a range of approx. 50 km.
Furthermore, I also noticed that in Sport mode and Towing mode another small buffer of +7% is retained. I.e. e.g. Above 25C then 27% and so on. The battery discharges below this minimum threshold at high power output in all modes, but then immediately recharges.
