The development from the four-seater 530 prototype to the 901 is one of the most exciting decades in Porsche history. Numerous previously unpublished original documents provide a detailed picture of concepts, designs, backgrounds and decisions. A central role is played by the Type 695, whose final design was eventually built as a one-off and became the model for the Type 754. File notes, minutes of meetings and memoranda document why the great Porsche fails and Ferry Porsche makes a drastic cut and embarks on a completely new project: the T8, soon receives the type number 901 and is presented to the world public in September 1963
