It's not fancy, as almost no-one gets to see it, but some manufacturers are applying varying degrees of panelling on the undersides.
Few cars have really smooth undersides, but there's a growing interest to lower drag underneath the car, so we'll see ever more of it.
The usefulness of an air dam decreases as the underside becomes smoother, but it's OK to combine both - one way is an air dam dropping down to the level of a belly pan
