Things I like, I love how low it is. I like how it doesn't really look as funky as many of us were fearing, it looks better than the aero graphic for instance was making it out to be. The beltline looks really high which from a visual standpoint is kinda disappointing, but like others have said, parts of the actual beltline might be lower. 

Being a bit further away from the body may decreases the effect the turbulence from the mirror has on the aero of the body.

Two questions:   1.) is there a thread discussing this on GMI   2.) what does BORG think? His camo-vision is legendary.....😂

I'd agree it seems odd, but Ford went out of their way to call out the aero of the mirrors in previous presentations.....shrug

I grabbed some screenshots near other vehicles:   Here's next to a Prius:   There's a Subaru Outback on the left (see it peeking out in front of the Ranger), and a Honda CRV to the right:   Nissan Altima next to it:       Tesla Model Y between the truck and the bus:

People who saw it said it's smaller than a maverick, so your calculations of 55 inches make a decent amount of sense. A maverick is already low to the ground, but this is when lower.    This would also support the claim Jim Farley made about it not being a conventional truck. It's closer to a ute if those dimensions are accurate. 

The mirror arms seem to stick out pretty far compared to the size of the truck. Almost like towing mirrors... Which one would think is a negative for aero. 

I wish I had brought my computer with me that has photoshop to overlay over the Maverick graphic below, but my crude quick look at its height using lines based off the 20" rims pegs it at maybe 55" tall, which is is much lower than the Maverick, which comes in at 67.7-69.4"......not sure if that math actually makes sense or not.......the 55" range puts it right at Honda Civic height             It does look tiny in this photo....

Yeah I’m not going to bother trying to decipher the front.    I think you can see roughly where the glass actually goes down to due to the bumps and corners here:   I think you can also determine there is no significant buttress. It just appears absent here.   They seem to have slapped on cardboard to obscure the shape of the bed, but I think its sort of tapered upwards.

Isn't coyote ugly part of the charm? people don't buy G-Wagens because they are beautiful (well maybe in an english Bulldog sort of way), they buy them to make a statement. "I have Snap On tools in my kitchen junk drawer and I'm more offroader-er than you."
