About the Sierra Sapphire Cosworth
The Ford Sierra Sapphire RS Cosworth 4x4 (1990-1992) was the four-door with permanent four-wheel-drive and 220hp. More practical, better traction. Around 12,250 built (including 2WD Sapphire). The usable Cosworth. Values from £30k.
Known Issues to Watch For
Sierra Cosworth: Engine - YB Cosworth turbo. Head gasket critical (especially early RS500s), timing belt every 36k, water pump, turbo (Garrett T3/T4). Strong if maintained. RS500 - even more stressed. Gearbox - T5/MT75 5-speed strong. 4x4 (Sapphire) - viscous coupling, transfer box. Body - Less rust than 70s Fords but check sills, inner wings. Rear spoiler expensive. Authenticity - Check chassis plate, build spec. Values rising - RS500 commanding serious money. Budget £4-8k annually.
