Graham Robson is one of the most experienced, prolific and versatile motoring historians in the world, and is recognised as one of the authorities on anything concerning Ford in motorsport. He watched his first F1 GP - at Aintree - in 1955, and has never lost touch with the cars, the technical trends, and - most importantly - the personalities connected with placing Ford, and Cosworth, at the pinnacle of F1. He was close to Cosworth, both as a working historian, and as a personal friend of the company's senior personalities, throughout the lengthy period covered by the DFV - and considers it an honour to have been entrusted with the compilation of this amazing story.
