This is the story of an incredible and very rare car. Road tests examined the 210bhp, 150mph road car's performance, magazines hailed it as one of the greatest Porsche 'specials,' and rumour says that the last front-engined models could have threatened the sales of Porsche's flagship 911, causing the 924 Carrera to be 'killed off.' From its early conceptual phase and the 924 Rallye Turbo of 1979, to the prototype 924 GTR/P that tested at the Paul Ricard Circuit and went on to place sixth at Le Mans in 1980, this book records the model's evolution to excellence, based on extensive research in Porsche AG's own archives. It covers the 406 Homologation models, built to qualify for Le Mans, and the 59 very special competition models, as well as the 17 GTR racing models. With race details covering Europe and the USA, from the Sports Car Club of America production D racers, to the GTO and Trans Am class 924 GTRs of the mid-80s, this is the first time that the full history of this rare supercar has been told.
