The Ford Escort RS Cosworth was designed according to the Group A homologation specifications for the World Rally Championship, in which it competed between 1993 and 1998.

Ford developed the Sierra Cosworth 4 × 4 chassis based (shortened) and mechanics car, equipped with the “Cosworth YBT” engine, a 2.0 L (1,993 cc) turbocharged 4-cylinder with 227 horsepower and all-wheel drive Cosworth transmission.

The «RS Cosworth» is instantly recognizable due to its huge “whale tail” rear wing.

The road version «RS Cosworth» was available in the Escort range between 1992 and 1996 in very limited numbers, which together with the sporting successes, make the Escort RS Costworth a «iconic» and highly desired sport.
