The Ford Sierra RS Cosworth was first shown to the general public at the Geneva Motor Show in March 1985. It was originally launched in July 1986 as a limited-production, special edition performance saloon, but turned out to be rather more popular than expected. 5545 were manufactured and 500 of these were converted into the Sierra 3 door RS500 Cosworth
The Cosworth featured fantastic performance, both on road and as a touring car (RS 500) and rally car. The shell was a standard 3-door sierra, but that's where any similarities to the standard family car ended! There was a whopping great aerofoil mounted on the tailgate, the suspension was lowered and fat alloy wheels and tyres were also added. The interior was more sporty and luxurious, too.
Cosworth were, of course, a racing engine manufacturer and their YBB series engine was used in the first Cosworths. 1988 saw the launch of a Cosworth that used the more subtle Sierra Sapphire body, and a third generation 4WD version was launched in 1990.Engines:
Cosworth YBB, 204 hp (1986)
Cosworth YBD, 224 hp (1987)
Cosworth YBB, 204 hp (1988-1989)
Cosworth YBG/YBJ, 220 hp (1990-1992)
