Another Porsche book, this time the story of the iconic 917, arguably the most dramatic sports-racing car ever built and certainly the pride and joy of the Stuttgart race team. Author Gordon Wingrove worked for John Wyer during the halcyon days of the 917 so he knows what he’s talking about, and his book is an insight into the mysteries and complexities of endurance race engineering. The book is technical, and very detailed, so one for the 917 addict, perhaps rather than the general reader. There’s a foreword by Hans Metzger of Porsche. reviewed by Motor Sport March
