Upper surfaces of the body, flanking the greenhouse represent very little deceleration, with high velocity, low pressure. Nothing like a streamline body, in which the body would boat-tail from the same point as the roof apex, building pressure the entire length of the aft-body.
I believe that a close reading of Doctor Wolf supports everything I mention. It's at home, not at hand.

Classic example of Aerohead changing the proposition. Now it's not about fastback cars, now it's about - well... I don't know quite know what.
Can someone explain?
Reading it again, I think it might be Aerohead telling Porsche how they could have made things so much better by following a mythical streamline body - one that apparently has low drag
and low lift!
Gosh, what a shape that would be - and yet, as far as I know, no-one has ever produced such a road car with this measured data (low drag and zero lift) available.
All these professional car company aerodynamicists, yep, they're just stumbling about in the dark waiting to hear from Aerohead.
