I agree with Sparkyq probably the turbos or a mechanism working with them. I have 2 twin turbo cars and what you are stating sounds similar to what i hear when accelerating hard then immediately lifting. The sound from under the car could be because you are travelling at speed or if it is standing still could be an echo from the engine compartment working its way out and under the car.
The same type of sound comes from my 911 turbo and it sounds as if its coming from the side front as you know its a rear engine car. My wifes X5M sounds like it is coming from the rear.
I hope that helps.
