From 1986 until 1989 Ford UK made a special version of the brand’s mid-size Sierra, called the RS Cosworth. As the name implies, Cosworth produced engines for these special edition lift-backs and sedans – a 2.0-liter turbocharged four-cylinder that made between 204 hp and 224 hp depending on the year and trim level.
The most identifiable aspect of the RS Cosworth is the large wing that bisected the rear window and included a center mounted support pillar. The 1987 RS500 Cosworth took things a step further by adding a secondary lip spoiler on the trunk’s leading edge. Compared to the latter Escort RS Cosworth, the Sierra’s wing sits lower down in comparison to the roof-line.
