Do you still think that size of the grille opening is not an indicator of cooling load? Any comments?
Keep in mind, the F150 ev is probably both more powerful and heavier than its ICE counterpart.

I am not sure what point you are trying to make. I am interested in cooling drag as a proportion of total aero drag, and on the BEV cars for which we have the data, the cooling drag proportion is not at all low. Unprompted, an expert car aerodynamicist I have been working with said much the same to me the other day - the cooling drag of electric cars isn’t actually low, as had been expected. If you have data on cooling drag as a proportion of total drag, please share it.
