Not exactly.

I believe the 75' Turbo, Weissach, and Carrera tail were all whaletails. But they differed somewhat in the venting. The 75' Turbo had a secondary vent. In 76' the secondary vent got larger for more heat dissapation. The Weissach tail doesn't have this vent because it produced less heat. Later on in 82' the whaletails started being made with one large vent that was flat like the tea tray spoiler. These I think are often refered to as Carrera tails. They also recieved a larger rubber surround area.
