I've made zero effort to be acquainted with current hydrogen technology,so I'm worthless on that one.
The side elevation looks okay.
Without an extreme closeup of the nose,it's hard to know how 'porous' the grille area is.It may actually allow only little air to pass through.
The outboard areas,if followed by some body camber will still have attached flow,as they'd be in a favorable pressure gradient.
It doesn't have the 'bubbly' appearance of which the 2014 Tundra was pilloried for,having to undergo some 'man-it-up' squaring so as not to scare off potential buyers.
The raised hood may have to do with the latest pedestrian safety regulations.Don't know.
