Today, one cannot escape the fact that the words 'Porsche' and 'racing' go hand in hand. This book follows Porsche's year-by-year progress in top flight racing, and looks in detail at the pure competition cars that brought the German marque such immense success on the tracks and worldwide acclaim. This particular volume starts with the story of the giant-killing 550 Spyders of 1953 vintage, and takes the reader through a series of racing models, including the glorious 917, up to 1975 via contemporary photography and words from an acknowledged Porsche authority. A second volume covers the years 1976 onwards. The book includes detailed year by year coverage of Porsche's top class racing exploits, accompanied by over 600 excellent photos.
