Escort RS Cosworth



The Escort Cosworth was based on the outgoing Sierra Cosworth floor pan, although this Escorts basic shape looks the same as the every day Mk5 Escort the rear 1/4's were built to be a little longer. This made the mating of the shell to the floor a little easier.

Compression ratio 8:1

The 2 door shell needed extensive modifications by Ghia to use the larger Cosworth engine and transmission.

The Escort Cosworth was based on the outgoing Sierra Cosworth floor pan, although this Escorts basic shape looks the same as the every day Mk5 Escort the rear 1/4's were built to be a little longer. This made the mating of the shell to the floor a little easier.

Tilt and Slide FFSR (Factory Fitted Sun Roof), Electric windows and mirrors, Central Locking, and Tinted Glass, were all standard equipment.

The rear tail gate featured a large double whale tail spoiler, bringing back memories of the Sierra 3 door Cosworth. The Escort was later available with a smaller rear spoiler which was necessary for type approval in countries such as Switzerland.
