In the video posted: https://www.youtube.com/watch?v=IJ5sU2r-xxw&t=1100s #NathanArmstrong stated that the #APTERA original design was based upon a shark. Because the shark cannot access the bottom it actually arc its body to force it down to get access to the bottom of the ocean floor.
My logic tells me the faster the #APTERA goes the more it will hug the road. That is why they do not have any concerns that the light weight of #APTERA will lift off once maximum speeds are reached on the road :) Without the use of spoilers or fins like in F1 racing cars to push the vehicle down that would increase drag etc. Brilliant #APTERA!
There are many hidden features or technology hidden in the earo-dynamic design of the #APTERA that is not obviously noticeable or known.
