The original Ford Sierra RS Cosworth was the first Ford to wear the Cosworth badge and was presented to the public at the Geneva Motor Show in March 1985. Launched for sale in July 1986, and based on the 3-door Sierra body shell, it was designed by Fordโs Special Vehicle Engineering (SVE) and was powered by a Cosworth-designed 2-liter turbo engine of now-legendary repute.
In total 5,545 cars were produced โ of which 500 were sent to Aston Martin Tickford for conversion to the Sierra RS500 Cosworth. If the RS Cosworth was a homologation car, the RS500 was an evolution special. The RS500 was announced in July 1987 and had a mechanically uprated Cosworth engine (more similar to the one to be used in competition), with power boosted to 224 horsepower, modified bodywork and the cachet of being hand-assembled.
Recently refreshed and with a fresh MOT, E378 TKN will be presented at Race Retro on its original wheels. Silverstone Auctions are proud to have been involved in the sale of many cars at world-record prices, many of them Fords. With Fast Fords seemingly knowing no bounds in their desirability, and this one believed to be the very best example of the ultimate 1980s Fast Ford, we invite and encourage any serious collector to inspect this superb, 5,000-mile Cosworth, as its type is unlikely to be found again.
