If it weights almost the same like 520d, then the weight difference between old and new should be as follows:
730d will be the bi turbo i4, so we take 525d as basis,compare 525d to 530d-the difference is 55kg. So we take out 55 kg from 1915 (730d i6) to compare apples to apples and it equals to 1860kg if we had a bi turbo 4 cylinder 7er at this generation. 520d is 1705 kg which makes a difference of 155 kg between the new 7er and the old (actual) one.
