Development
Ford developed the car around the chassis and mechanicals of its predecessor, the Sierra Cosworth to accommodate the larger Cosworth engine and transmission, whilst clothing it in Escort body panels to make it resemble the standard Mk IV. Designed under the guidance of Rod Mansfield and John Wheeler of Ford's SVO department, the styling was carried out during 1989, by Stephen Harper at MGA Developments in Coventry. The spoiler was added by Frank Stephenson, who originally proposed a three-deck piece. The body tooling was created by coachbuilders Karmann at their facility in Rheine, Germany, where the cars were manufactured.
Changes were made to the engine management system and a new turbocharger was fitted. Permanent four wheel drive with a 34/66% front/rear split came courtesy of an uprated five speed gearbox as used in the Sierra Cosworth. Recaro sports seats came as a standard fitment. Later production models were available without the oversize tail spoiler although by far the majority were still ordered with it. Like its Sierra predecessor, they are commonly nicknamed "Cossie" by enthusiasts.
The Escort Cosworth was a rare car, with 7,145 vehicles produced from the start of production on 19 February 1992 until the last car rolled out of the factory on 12 January 1996. A tiny number were unofficially imported to the United States, where it was considered one of the greatest performance Fords of all time.
Two versions were produced. The initial 2,500 units were "homologation specials" used to get the FIA accreditation for entry into the World Rally Championship. They were fitted with a Garrett T3/T04B turbocharger. Among these initial units, a handful were badged as Motorsport versions, these lacked certain refinements such as a sunroof and sound deadening.
The initial cars included features that, although they made the Cosworth a more effective car, did not enhance it as a road vehicle, and once the rules were satisfied Ford attempted to make the car less temperamental and easier to drive under normal conditions. The second generation, starting production from late 1994, were fitted with a Garrett T25 turbocharger, a smaller unit which reduced turbo lag and increased usability in everyday driving situations. With these later models, the 'whale tail' spoiler became a delete option.

Famous quotes containing the word development:
“On fields all drenched with blood he made his record in war, abstained from lawless violence when left on the plantation, and received his freedom in peace with moderation. But he holds in this Republic the position of an alien race among a people impatient of a rival. And in the eyes of some it seems that no valor redeems him, no social advancement nor individual development wipes off the ban which clings to him.”
—Frances Ellen Watkins Harper (1825–1911)
“Creativity seems to emerge from multiple experiences, coupled with a well-supported development of personal resources, including a sense of freedom to venture beyond the known.”
—Loris Malaguzzi (20th century)
“I’ve always been impressed by the different paths babies take in their physical development on the way to walking. It’s rare to see a behavior that starts out with such wide natural variation, yet becomes so uniform after only a few months.”
—Lawrence Kutner (20th century)
