farina:

These (early) design sketches of Emiel Burki (Porsche Design Team) give us an impression of the final deal. And like many other sketches they are exaggerated to pronounce special subjects. For example: The roofline of the real thing is not so low as you can clearly see at the prototype. The reason why Porsche shows it? Hm... Marketing? Create tension? It´s a long time until september... And the sketches clearly show a 4-door sedan.

My apologies. My eyesight is not what it used to be.
