Enormous high consumption ETron GT and Ruckler in comfort mode

Hello everybody, I have a GT as a new car since mid-October 23. It has 245 and 265 winter tyres from Pirelli in the front. I have the following questions and hope that I can find answers here. On the one hand I have the feeling that the car has too high consumption. Long-term: 31.6 kWh/100km. Photo I add. I got the car new at the “winter time” and of course I have almost always the heating on, but is that so right? Next I am surprised that if I for example on the highway at 220 km/h walk off the gas, the car should recuperate, but nevertheless the remaining kilometers go down there with the rest kilometer indicator. On the highway generally the kilometers go down like warm semmel. At 180 km/h, I would probably only manage 100 km. Is that also so with you? Then I have another problem. Therefore, I brought the car to the dealer, so that they look at it. The car has a clear jerk when accelerating in the Comfort mode, or in a balanced drive. So also in individual mode. In my opinion, something is not right and has nothing to do with Comfort. If I step through the gas, the car accelerates discreetly and suddenly gets a real unpleasant jerk and then gives it full throttle. The dealer has no explanation for this and said afterwards that this is normal. I can’t believe it. Does someone have the same experiences? Thank you for your answers.
