In 1955, Mercedes-Benz wins the sports car world championship with the racing car 300 SLR (W 196 S). In addition to the titles achieved that same year in the formula 1 world championship and the European touring car championship, this success is proof of the unprecedented dominance of a single manufacturer on the stage of international automobile racing. Stirling Moss and Juan Manuel Fangio, the most successful drivers of their era, celebrate impressive double victories in the 300 SLR at the most demanding road races in the world, triumphs that continue to afford this unparalleled racing car lasting fame to this day. Based on extensive research in the archives of Mercedes-Benz Classic, this book provides exhaustive and authentic documentation of the technical development of the W 196 S. All of the races as well as the biography of each individual vehicle are presented with the aid of images and illustrations, some of which have never before been published. Its high-quality design and exquisite features make the book a true collector's item.
