The transition from the 356 to the 901 has never before been documented as precisely as this - it is the purpose of this book to shed more light on this exceptional period, to describe the genesis of the 901. It goes to the very heart of the Porsche brand - to the creation of the 901, which rapidly transformed into the 911. Over the last 20 years, author Jurgen Lewandowski - whose personal library now amounts to more than 4,500 books - has initiated, written, and edited around 60 books on the history of the automobile and the development of new models.
