Turbo Legend

When Ford and Cosworth joined forces in the mid-1980s, few could have predicted that their collaboration would create one of the most celebrated performance cars of all time. Turbo Legend: The Ford Sierra RS Cosworth Story chronicles the complete saga of a machine that redefined speed, engineering, and street credibility across Britain and beyond. Born from the demands of Group A touring car racing, the “Cossie” became an instant icon-its whale-tail spoiler and turbocharged heart symbolizing an era of raw, unfiltered performance.

From its debut as a homologation special to its total domination on racetracks worldwide, this book traces the Sierra RS Cosworth’s transformation from competition weapon to cultural legend. Each chapter dives deep into its engineering brilliance, its triumphs under the banners of Eggenberger and Dick Johnson Racing, and its evolution through the RS500 and Sapphire 4×4. It captures the drama of victory and the inevitability of change as regulations, technology, and time reshaped its world.

But Turbo Legend goes beyond the track. It explores how the Sierra RS Cosworth came to embody 1980s Britain-equal parts rebellion, innovation, and pride. Through stories of owners, tuners, and collectors who have kept the flame alive, it reveals how the sound of boost and the whistle of a Garrett turbo became more than noise-they became emotion, memory, and heritage.

For enthusiasts, engineers, and anyone who ever felt their pulse quicken at the sight of an RS badge, this is the definitive story of Ford’s greatest performance car. Meticulously researched and written in compelling narrative style, it celebrates the car that didn’t just win races-it won hearts.
