I understand what you are saying but i dont think its the airflow that is the issue here with this particular grill, i think its just either mediocre or unfinished design. I looked carefully at their other grill options with bars down the middle (used across all trims too, both gas and diesel) and it hides everything behind the grill pretty well. But this “sport” grill version used in 250/350 line does not unfortunately.Something the Ford engineers are likely contending with is airflow as they push these super high power and tow ratings. Remember that this same grill needs to function in a maximum tow capacity scenario.
I agree the Explorer grill, with its smaller holes, looks better, but it’s also more restrictive to air flow. Smaller holes means more plastic in front of the radiator.
No idea how big of a factor that is in the new design being so see through, but it’s definitely a factor.
