Does someone know if Diamler AG shifts money from diffrent divisions..to finance R&D and so on?
Usually they do not. Usually there's no money shifting between divisions. According to my knowledge every Daimler division has it's own accounting / book-keeping system. But I guess one division can land some money to other division if there's extra free cash available - since it's cheaper than eg. getting it from bank. But that's happening in emergencies only - when a certain division has a huge liquidity problem, while other has huge amount of free cash. Not a current situation within Daimler though.
The concern is there to provide synergies & some economies of scale advantages. But there is a tendency to make divisions financially as independent as possible.
But sure there is some common R&D going on within the concern - so I guess all the divisions participate with their own resources. Some less, some more. In this case it can be said one division helps another. But not directly financially.
It's not like - we'll cancel some commercial vehicle plans & pour the money from truck division into passenger car division.
They have learned how damaging can be when one division lives on & eats other divisions' money. Remember "DaimlerChrysler - the horror movie"?

I wonder if this was the result of BMW's buy one get one free sale?
