Dedicated to race car driver Jaun Manuel Fangio.  According to Horacio Pagani:

Juan Manuel Fangio was much more than a great champion. His accuracy, his uprightness, and his human and technical sensibility were among his qualities, typical of the old-time men, they have been for me, an example and an inspiration source. Very often, I ask myself how something so material, like a drawing or a technical choice, can express and convey the philosophy of such a men. The name of “el coche”, the way he used to call the car, should have been Fangio F1. He followed the project with a strong enthusiasm, according to his ideas the F1 had to be innovative, safe and had to be powered by a Mercedes-Benz engine. He then passed away and as a sign of respect I did not dare to call the car Fangio F1 and I decided to name it Zonda, “el viento de los Andes”. Today, after years spent in a rigorous search for perfection, the result is the Zonda F, a car that I wish to dedicate to Juan Manuel Fangio, the man who has made everything different."

The Zonda F features cosmetic changes such as the front grille, carbon fiber surrounding the headlights, carbon fiber mirrors, and different rear grille.
