I don't understand the two VW-P4 but only one VW-P3 profiles.
It looks like if the Dasher's profile was pushed to 74° it would be a slippery as the Golf/Rabbit. Does it make sense to apply the lower left scenario to the upper profile?

Perhaps these were all wind tunnel mock-ups of the mkI Golf/Rabbit. The 34 degree in the lower left looks closer to the mkIV Golf (my car) and if I read the graph correctly the triangles show lower Cd. Somewhere on here I remember seeing the back should be chopped at vertical for lowest drag.
