Mein Auto: 2011 528i
On the 528's my money is on this being a purposeful programming for fuel economy in D particularly since in DS there is no lag. At least that's how it seems with mine.

My Enclave had a similar MPG minded programming that created what felt like dead spots when accelerating. After a reprogram the dead spots went away and the SA warned it may decrease fuel economy, which I didn't care about (it's an 8 passenger vehicle...fuel economy isn't at the top of the list for this particular vehicle).
