it started out as drip pan, so you would not get oil drips on your driveway. (older cars)

then it evolved into a shield to direct more air through the radiator, past the engine and through the transmission tunnel to cool the transmission. the trays got longer and longer.

then it turned into an aerodynamic aid.
