The pressure portion of the profile drag is governed by the pressure differential between the front and rear of the vehicle.
The base pressure behind the vehicle is governed by the separation point.
The only way to 'increase'the pressure and thereby lower the drag,is to move the separation point back,ideally to the very back,eliminating separation completely,then you're left with only skin friction.
Induced-drag can be virtually eliminated thanks to Dr.Morelli's "banana-car" of 1978.
