* The lower lift of the LEAF can be explained only by higher pressure acting over the aft-body.
* Had the flow actually been attached on the PRIUS, it's rear lift would have been less than the LEAF.
* The only explanation possible is, that the PRIUS is experiencing flow separation. Just like the 2010 Audi A7 Sportback. 2020 Porsche Taycan.

It's amazing how to a hammer, everything looks like a nail...
The Leaf has far better undercar aero than the Prius - something that perhaps might explain its lower lift? You seem to be forgetting half of the body shape!
As for the Taycan having upper body separation - you are joking, aren't you? Where's your evidence for that - comparison with your make-believe ultimate template? If so many people hadn't been sucked into believing such rubbish, it would be just laughable.
It's really obvious that no matter what anyone shows through testing, or whatever anyone shows through technical references, or what anyone says in citing current car aerodynamicists, you will not change your views. To be honest, that is just gobsmackingly arrogant.
