It gives you more useful internal volume, kills separation, kills lift,to make a 'neutral' lift body.
Drag coefficient is dependent upon the Vergungungsverhaltnisse (the ratio of the length of the aft-body,divided by the body height (not the overall height of the car), presented as a ratio. The lowest drag is achieved at V = 5:1.
(My bold in the above quote.) You are spreading lies again. As anyone who doesn't subscribe to the strange theories of 'Aerohead' would immediately realise, the shape you nominate has a lot of lift. The Porsche Taycan is just the latest example - but a good one because we have data for it.

Note for people keeping track, 'Aerohead' is later in the quote again spreading misleading rules of thumb.
