XR4i and Other Sporting Models
In 1983, the high-performance XR4i version was introduced. It utilised the same 2.8 L Cologne engine as used in the Ford Capri 2.8 Injection of that era and sported a restyled version of the 3-door Sierra bodyshell. The double rear spoiler and curious multi-pillared rear windows were considered over-styled by some prospective buyers, and the car never achieved the cult status of the smaller Fiesta XR2 and Escort XR3i. A version of the XR4i with a 2.3 L turbocharged engine was sold in the United States as the Merkur XR4Ti. The XR4Ti was raced in Europe, most notably by Andy Rouse who used one to win the 1985 BTCC.
In South Africa, there was a 3.0 L V6 version, called the XR6, also made in South Africa was a limited run of 250 V8 XR8s for saloon car racing homologation in 1984. These were based on the Ford Windsor 302 engine.
In 1985 the XR4i was replaced by the XR4x4, which was based on the five-door hatchback, had four-wheel drive and was powered by the same 2.8 L V6 engine. By the end of its production in 1990, 23,540 had been produced. From 1990 to 1993 the XR4x4 was available with both the revised 2.9EFi and 2.0 DOHC EFi engines. The XR4i also made a reappearance (as a badging exercise) in 5-door form but with the DOHC 2.0 engine instead of the V6.
In 1989, Ford nodded towards its past and created the Sierra 2.0i 2000E, a model name used with limited success on the Mk3 Cortina. The Sierra 2000E had two-tone metallic paint, alloys, light grey leather interior, and a trip computer in addition the standard features on the 'Ghia' models. It was only available in saloon form and a limited number of models were sold between 1989 and 1991. Ford used this to showcase the new DOHC twin cam engine which was also released in 1989.
In Argentina the non-injected XR4 model was equipped with the Taunus 2.3 engine and was produced between 1986 and 1991. In this market the most direct rival was the Renault Fuego 2.2.
In July 1986, a special version called the Ford Sierra RS Cosworth was launched, using the 2.0 OHC bottom end with a 16V DOHC cylinder head specially developed by Cosworth. With the Cosworth Garret T3 turbocharger and intercooler setup the engine produced 204 PS (150 kW; 201 hp). It was designed by Ford's Special Vehicle Engineering (SVE) group and made in Ford's Genk factory in Belgium for use in group A. It was based on a three-door Sierra with the dashboard from the Merkur XR4Ti. The car was available in only white, black or Ford's 'Moonstone Blue' and only 5545 were made. All RS Cosworth and RS 500 were made in Right Hand Drive. Racing conversion were done with the European Merkur dashboard.
In 1987, a 225 PS (165 kW; 222 hp) Sierra Cosworth, the RS500, was sold alongside the regular version. Only 500 were produced as the minimum number of road-going cars required to meet with newly introduced homologation racing rules, allowing it to compete in evolution form for group A racing. The car was modified by the Tickford Engineering Company in conjunction with Ford. Revisions included uprated brakes and larger brake cooling ducts and modified front and rear spoilers (a second smaller rear spoiler was added beneath the large "whale-tail"), a modified front bumper to allow extra cooling for a larger intercooler, as well as various engine upgrades including a larger turbocharger and a second fuel rail (which did not operate on road models). Race outputs were as high as 550 bhp (410 kW; 558 PS), in which the Sierra dominated group A series around the world.
Racing versions of the Cosworth were highly successful in European and World touring car racing throughout the late 1980s and early 1990s', and the RS500 helped Ford to win the manufacturer's title in the 1987 World Touring Car Championship. Ford was forced to fall back on the Sierra for rallying from 1987, after the banning of the Group B formula. With only rear-drive, the Sierra struggled to compete on looser surfaces but was very quick on asphalt, Didier Auriol winning his first World Championship rally in a Sierra in Corsica, 1988. It was replaced by the 4x4 Sapphire version from 1990, which never managed to win a World Championship event but became a popular and successful car in national championships. The Sierra was replaced by the Escort Cosworth in 1993.
In 1988, a new Cosworth was produced which was based on the Sierra Sapphire saloon. 13,140 were produced until it was replaced in 1990 by a four-wheel-drive version, the Sierra Sapphire RS Cosworth 4x4, of which 12,250 were built. Its replacement came in the form of the Escort RS Cosworth which appeared in 1992, which used a shortened and developed version of the Sierra platform and running gear but clothed with an Escort-esque bodyshell and the return of the whale-tail spoiler.

Famous quotes containing the words sporting and/or models:
“The Boston papers had never told me that there were seals in the harbor. I had always associated these with the Esquimaux and other outlandish people. Yet from the parlor windows all along the coast you may see families of them sporting on the flats. They were as strange to me as the merman would be. Ladies who never walk in the woods, sail over the sea. To go to sea! Why, it is to have the experience of Noah,—to realize the deluge. Every vessel is an ark.”
—Henry David Thoreau (1817–1862)
“Friends broaden our horizons. They serve as new models with whom we can identify. They allow us to be ourselves—and accept us that way. They enhance our self-esteem because they think we’re okay, because we matter to them. And because they matter to us—for various reasons, at various levels of intensity—they enrich the quality of our emotional life.”
—Judith Viorst (20th century)
