Rare 1987 Ford Sierra RS500 Cosworth Hits The Auction Block

The Ford Sierra RS500 Cosworth is an iconic vehicle from Blue Oval history that was conceived to homologate that particular model for Group A Touring Car racing. Developed in conjunction with long-time partner Cosworth, this special machine found tremendous success in that regard, not to mention the fact that it attracted an entirely new generation of fans to the brand. Every once in a while, a road-going version of this special machine pops up for sale, including this modified example, chassis number three, and the very first example ever built. Now, fans of the Ford Sierra RS500 Cosworth have yet another chance to bring one home, as this 1987 model is going up for grabs at Silverstone Auctions‘ upcoming 2023 Supercar Fest in the UK.

This particular Ford Sierra RS500 Cosworth is number 215 of 500 produced in total, and it has just 23k original miles showing on the odometer – a low sum by any measure. As such, it’s in solid, mostly original condition with the typical bowed rear shelf, as well as some normal seat wear, but essentially zero additional flaws. It was repainted in its original hue back in 2015, however, and it has held up quite nicely since then.

The star of this proverbial show, of course, is its heart – the turbocharged 2.0L powerplant designed by Cosworth that produced 224 horsepower, along with beefier brakes, unique bodywork, a rather iconic rear spoiler, and hand assembly. Combined with the 5,000 “regular” RS Cosworth models produced, it helped satisfy Group A rules, and perhaps more importantly, it became a true icon of this particular era.

As such, it’s no surprise that Ford Sierra RS500 Cosworth examples go for big money on the rare occasion that one hits the auction block these days, and this one should prove to be no exception. In fact, it touts an auction estimate of £100,000-£120,000 ($123,607-$148,328 USD) which would be right in line with what we’ve seen these special cars hammer for in recent years.

    My dream car during my youth in Argentina, when the Sierra XR4 was the “Mustang” of the Pampas, lol. Thanks to the corrupt TC2000 organization rules of that time, the Renault Fuego (front wheel drive) won most championships.

    In 1983 we were on a Ford of Canada dealer trip to Switzerland for the ‘Ford Swiss Road Rally’ (just a tour through the beautiful country, no speeding allowed)!! At the opening reception Ford of Canada President Ken Harrigan grabbed and took me over to meet the Ford Europe Managing Director. I think it was setup but the director threw me his keys and said try this out. Sitting in front was a Ford Sierra coupe with, if memory serves, a bad *ss 3 liter V6 and a 5 speed. I drove up the long hill beside our hotel and OMG did that think ever work. So when we got the news that we were getting the Merkur and XR4ti I figured we would get something similar. Nope, what we got wouldn’t pull the skin off a rice pudding. What a disappointment.
