BMW X1 xDrive25e. Where does the high price come from?

The technical data and the basic price of the new X1 hybrid have now been released for me surprisingly the high price point of 45,250 €. Does anyone have an idea how this can come about? The sDrive 18i is 320€ more expensive than the 218i Active Tourer with the same motorization on the same platform. Therefore, I would have expected that the xDrive25e would also cost 320€ more than the 225xe Active Tourer. That would be 42,850 €. – 240€ more. The minimally larger battery will hardly be due to the fact that the cost of battery systems will fall rather than rise. Additional standard equipment compared to 225xe was not announced. It just seems to me that the customers at BMW should pay the manufacturer’s share of the environmental bonus. Very unsightly.
