About the Ford Sierra RS500 Cosworth
The Sierra RS500 Cosworth is the definitive evolution of Ford's Group A homologation project. Converted by Tickford in a limited run of 500 units, it features a reinforced YBD engine block, a larger Garrett T04 turbocharger, and a massive intercooler designed for competition longevity. Visually distinguished by its 'whale tail' spoiler and additional rear lip, it was built to dominate the track rather than the street. It remains one of the most sought-after 'Fast Fords' due to its immense motorsport pedigree and raw, turbo-lagged driving character.
