The final evolution of the game-changingSierra CosworthOriginal, unmodified and unmolested, arare survivor in this sort of conditionComprehensive history. Owned and shown by numerous RSOC membersOffered from the collection of a truemarque enthusiastThe original Ford Sierra RS Cosworth was the first Ford to wear the Cosworth badge and was introduced at the 1985 Geneva Motor Show as a means of homologating the Sierra for 'Group A' Touring Car racing. These regulations dictated that a minimum of 5,000 were built and sold and eventuallyFord complied with 5,545 finding homes. Based on the three-door Sierra bodyshell, it was designed by Ford's Special Vehicle Engineering (SVE) and was powered by a Cosworth-designed 2.0-litre turbo engine of now-legendary repute. The RS Cosworth used a 204bhp 2.0-litre DOHC engine with a Garret T3 turbocharger and inter-cooler enabling it to reach 62mph in 6.8 seconds and a top speed of 150mph. In 1986, the Sierra Cosworth was a new kind of performance car - a blue-collar hero able to humble true sports cars.In 1988 Ford launched the Sapphire Cosworth, which was a little more discreet than previous Sierra Cosworths and, as the name suggests, it was based on the four-door Sapphire saloon which alsoutilisedthe existing 1993cc Cosworth twin-cam turbo.In January 1990, the third generation Sierra RS Cosworth was launched, this time with four-wheel drive. As early as 1987, Mike Moreton and Ford Motorsport had been talking about a four-wheel-drive Sierra RS Cosworth that could give Ford a competitive edgein the World Rally Championship, however,Ford Motorsport's desire for a 3-door "Motorsport Special" equivalent to the original Sierra RS Cosworth was not embraced. The more discreet 4-door version was considered to havebetter marketing potential and it was therefore decided that the new car should be a natural development of the second generation, to be launched in conjunction with the facelift scheduled for the entire Sierra line in 1990.The car presented here is a 1992 Ford Sierra Sapphire RS Cosworth 4x4 and is in super original, unmolested condition. A well-known example within the RS Owners Club, having had numerous members as previous owners, the car still wears all its original panels and is refreshingly in standard spec. Accompanied bya comprehensive history,this car has always been well cared for and belies its mileage of 108,000 miles (still just 4,000 miles a year!), with enthusiasts knowing that if these cars are well maintained, they are comfortable withhigher mileages, and often better for it than some low-mileage unused examples. A great way into the word of RS ownership.
