The launch of the Sierra RS Cosworth in 1985 was a giant step forward for Ford. Initially developed for competition homologation, it was soon one of the most desirable fast cars that the public could buy. Its performance, at the time, was truly astonishing and remains impressive today. It was also the first of a family of turbocharged sporting Ford Cosworth models, ranging through the Sierra 500 RS Cosworth, the Sapphire RS Cosworth, the Rouse Sport RS Cosworth, the Escort RS Cosworth and the Escort RS Cosworth Monte Carlo.All these cars are doubly desirable today, and owners and potential owners anxious to establish the cars' correct original factory specifications and equipment will find all the information they need here in this book, backed up by hundreds of specially commissioned colour photographs of outstanding examples. As in the other titles in our authoritative and successful Factory-Original series, all aspects are covered: body panels, external trim and badging, paint colours, interior trim, dashboard, instruments and switches, under-bonnet components, engine and transmission, lamps and all other features right down to the tool kit.
Of particular interest is the detailed information provided on components developed for and unique to the RS Cosworths as against the standard Ford models, and on the parts borrowed or adapted from a variety of Ford models to create the perfect recipe for the Cosworths.
