Ford Sierra Cosworth RS500
Although the RS500 first appeared on the motorsport scene in 1987, Ford’s Sierra project can be traced back two years prior to the North American-only Merkur XR4Ti. Named Merkur as a nod to the Lincoln-Mercury dealerships it was sold in, and the fact it was built in Germany, the XR4Ti found success in European racing thanks to imports by teams such as Eggenberger Motorsport and Andy Rouse. Such was the impact of these cars that Ford worked with these teams in question to help develop the upcoming Sierra RS Cosworth.
As now seemed par for the course with a new Ford touring car effort, the RS500 was an instant hit. Gaining homologation in August of 1987, RS500s lined up on the front of the grid for every single remaining round of that year’s inaugural World Touring Car Championship – and had it not been for a disqualification at the Bathurst 1000, they would have come away with the title, too. Instead, Klaus Ludwig and Klaus Niedwiedz ended the season just one point behind BMW’s Roberto Ravaglia. Illegal wheel-arches, allowing taller tyres, were the reason both Eggenberger cars were thrown out, and victory was handed to the quartet of local heroes Peter McLeod, David Parsons, Jon Crooke and the legendary Peter Brock, driving a Holden Commodore in what would be Brock’s record-setting ninth, and final, Bathurst win.
The RS500 took the touring car world by storm in the late ‘80s and into 1990, winning championships in Britain, Australia, Germany, Japan and New Zealand, taking victories at the Bathurst 1000, Spa 24 Hours, Guia Race of Macau and the Tourist Trophy on the way.
