I posted two images of exactly these things. Note the parenthesis I used around the word neutral, and words such a "similarities" & "equivalent." The wing has a single element in the center, flanked by two-element sections at either end. It would seem inevitable that spillover will be created from this design, resulting in something like a Y250 in terms of location and direction of rotation.
A wingtip vortex is all it is—most subsonic wings exhibit them. Why do you consider it a complicated phenomenon?
Ducati Panigale is 164hp/L or thereabouts in most iterations. Also a 10.5k rpm NA engine. It's within reason especially considering they aren't trying to get honda civic levels of life out of it.
Yes, you are right that was the Vulcan they reviewed on The Grand Tour. Except for the speed they did not have much to praise about it. The Vulcan and this Hyper car resemble quite lot IMO.
