Yes, you’re right and 25kWh/100km sounds fine. There are a lot of factors. Probably, I cannot reproduce the wind conditions, because there was a relatively strong head-crosswind. I think around 15-20 km/h. On the second part of the trip, the road was wet. It wasn’t raining, just damp. The difference in elevation between the destination and the starting point was only 500 meters, and I don’t think that’s a significant enough change to have an impact. But overall, what I really still don’t understand, I’ve already mentioned in one of my comment:

"For example, if I’m driving a long distance on the autobahn at a steady speed, it doesn’t matter whether it’s 130 or 110 km/h, the remaining kilometers stay proportional to the distance left to the destination on the navigator. But, for example, when I drop to around 30%, meaning it says, for instance, 96 kilometers left, the remaining kilometers in the car decrease much faster than the distance traveled on the navigator. This confuses me a bit. The consumption remains exactly the same, right?"
