If the LEAF roof wasn't cut short, it would be a 'Kammback.' And a 'Kammback' is simply a truncated long-tail ( lang-heck ).
In spite of the roof chop on the 'Drag Queens' LEAF, it had lower rear lift than the Tesla Model S.

* As to the Tesla Model S, I would describe it as a fastback-type form, perhaps compromised for rear visibility, with a spoiler incorporated into the contour to create the short deck, allowing for flow reattachment, and perhaps an alcove, from which an active rear pop-up spoiler might emerge. As on the original Model X.

When Aerohead is wrong, he simply changes the definitions of words. We've seen it before (attached flow isn't really attached flow if it doesn't match the template) and now a Nissan Leaf is fastback.

It's a fascinating world where reality can be altered to fit belief.
