At the beginning of the 1970s, the 911 era seemed to be coming to an end and a successor had to be developed. In 1977, Porsche presented the 928 and ventured into a new vehicle category, the Gran Turismo. This approach was not understood at the time, but today we know that the idea was right. The realization quickly grew that the concept was Porsche-like through and through and left nothing to be desired in terms of body layout, technology or design. Why the Porsche 928 was nevertheless not really successful and what its strengths and weaknesses were, but in particular how a Porsche 928 drives, is shown in this report, which has been supplemented with almost 100 photos, several sales brochures and audio examples, as well as the original owner's manual.
