The Ford Sierra RS Cosworth which was introduced in 1986 was a created as a homologation special to allow the car to compete in the Group A rally series.

The Sierra RS Cosworth shared little with the standard Sierra. Under the heavily modified body Ford's performance division had replaced the drivetrain from end to end. Powering the RS Cosworth was a 2.0 litre, turbocharged, four-cylinder engine which made 204 horsepower - with the potential to develop many more. This was coupled to a 5-speed, close-ratio manual transmission driving the rear wheels through a limited slip differential. To bring the Sierra RS Cosworth to a stop it employed anti-lock brakes with massive discs and four piston calipers.

The handling of the Ford Sierra RS Cosworth was superb thanks to stiff suspension, sturdy anti-roll bars, large alloy wheels and of course the limited slip differential. The massive downforce generated by the 'whale tail' rear spoiler further aided the handling characteristics.

In total just over 6,000 Ford Sierra RS Cosworths were produced. There were also 500 special edition Sierra Cosworth Evolution RS500 models manufactured. These were fitted with an even larger rear wing, and an engine developing 20 horsepower more.
