Won't work better too by avoiding more air to get under the car?

The raise of frontal area by that strip will decrease the mpg?

I'm talking about the black strip under the front bumper that says Karcher and has the license plate.
Maybe every vehicle should be considered on a case by case basis.
The car shown is a rally car.Past Ford rally cars suffered higher drag as a compromise to cornering downforce from induced-lift.
Front airdams,as reported in industry literature typically reduce drag on non-bellypan cars,then at some point,begin to increase drag as their frontal area grows beyond some point.
Bondo found this to be true on his F-150.
Some writers discourage the use of "rules-of-thumb" and advocate that every vehicle be investigated on a case by case basis.
It IS MY OPINION the the airdam pictured WOULD increase drag and degrade mpg.JMO.
