I wonder if the lower front "grill" opening provides some cooling air to components that might need it; e.g., the battery. Or, is it there for some aerodynamic purpose?

Also, I wonder if those hood vents have ducts to bring air from the lower front grill through the vents. When the smoke wand is placed to the left part of the grill, the smoke comes through the left hood vent. And when on the right, smoke emerges from the right vent. This seems to be done for aerodynamic purposes and likely keeps the front end from rising at speeds.

The battery is air-cooled.
Nothing is said about the power electronics or motor.
If nothing else, the grille opening would supply air to the air conditioning condenser coil.
Positioning the extractor slots where they are, taps into faster-moving, lower-pressure flow, allowing passive flow, without artificial delta- pressure power requirements.
There is a likelihood that one side is for motor cooling, and the other, AC.
And it's possible that the forebody generates zero lift / positive downforce. That was the case for my truck.

95% - there is literally nothing to cool

That would put the combined inverter and motor at 97%, same as the Tesla 'Raven' motor in the Model Y and Model 3.
Good news!

Especialy considering that even in highway driving this car does not require much power to sustain its speed.

I think its 95% battery to motor efficiency. Drive axles and their tripods are not very efficient. I think rear drive axle efficiency is around that same 95% percentage.

The crazy part is they had a facebook ad for this car and eveybody was pissed calling it and all of the aerodynamic cars ugly. I think it looks pretty good so I was surprised. Bascially just a bunch of people saying they want boxy SUV's with their hard earned money. lol

Really? Isn't that what Facespook is for?

True lol

My takes from the video compared to EQS which should be 0,20:
- Air exit scoops on the bonnet
- Closed wheels so no venting for brake cooling
- Bigger air curtains and taller in heigth
- wheelwell exit vents on rear edge in front and back tires. Nicely designed specially the front ones look neat
- Rear diffuser lowers and extends about 120mm rough estimate
- Mirror legs even thinner ones like they use in their sports or race cars.

Car propably has air suspension which lowers the car a lot, but it was not mentioned

According to Edmunds, in 2010, M-B had what they call an 'Airmatic' suspension system, claimed to reduce drag by 3%.
