The VW Flow body has a full,smooth belly and undergoes a 9.5% drag INCREASE when dropped to zero clearance.

As to suction,I'm not sure.
The pan's job is to eliminate turbulence and deliver laminar flow to the wake,or to a diffuser,which can decelerate the flow and deliver a higher base pressure,cutting pressure drag.
