Noble Sisters: Ford Cosworth, Sierra & Escort

Cosworth is a name that has made history in motorsport, renowned for its successes in Formula 1 and for creating sporty road cars that have become highly coveted collector's items today. Founded in 1958 by Mike Costin and Keith Duckworth—whose surnames combine to form Cosworth—both were former Lotus employees. Funded by Ford, Costin and Duckworth designed the engine that marked Formula 1 history: compact, lightweight, fuel-efficient (important for reducing vehicle weight), and reliable, it became the iconic engine for British teams.
