Everything Ford had hoped for - and more, much, much more. Not many cars become legends the moment they roll out of the factory but Ford's Escort RS Cosworth is one of them. Hand-built to take on the emerging Japanese dominance in World Rally, the "Cossie" proved a success on the forecourt as much as on the World's rally stages. But what is the true story behind this memorable car? Was the prototype really a hacked-about Sierra?
