yeah,you'll wanna peek under the nose.The leading edge of the wheelhouse/end of the belly pan leading up to the openings under the car has a molded-in airdam which extends downward and to the rear at a specific angle.There may be other companies who've done this,but Tesla's is the first I've noticed.
It reminds me very much of the 'taco' fairings MIT and other universities used on their very-low-drag solar racers.
The logic is to direct the air down,separate it right there,have the flow 'overshoot' the rear portion of the opening,then re-attach to the belly once the flow's cleared the opening.There would be a locked-vortex inside the wheelhouse
traveling with the car.It's very clever!
Exa's PowerFlow CFD is full-scale,so these sorts of details can be successfully 'tested' inside the computer.If you have the money.
