Product Information

I will make a very precise focus of the car, because it’s a really anticipated model, that deserves all interest. 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 make Ford competitive in the World Rally Championship. The Ferguson MT75 gearbox that was considered an essential part of the project wasn't available until late 1989 however. A word about the chassis : it is plastic, and from what I’ve heard it will stay like that, but the car is almost a roller. On my 4 examples, I have some rolling better than others. I can’t tell what will happen with models in production (mines are final samples), but I believe it will stay like that, which is a compromise admissible from my point of view. Oh, and the interior is also treated well, with this kind of tartan interior, with details up to the doors ! The price also suggests that both buyers considered this a one-off opportunity and indeed, it is unlikely to be repeated.” Sierra headlinings are prone to sagging (and can be repaired relatively cheaply), as are rear parcel shelves (which cost a bomb); a Cosworth should have a single-piece shelf with a plastic storage box (designed for a non-standard first aid kit).

Cosworth YB powerplant is the stuff of legends. It’s also the creator of nightmares if things go wrong. And they certainly do.Suspension: front MacPherson struts rear semi-trailing arms, coil springs, telescopic dampers; anti-roll bar f/r Tough and a bit tractor-like, the rear-wheel-drive Cosworth’s BorgWarner T5 gearbox can take loads of power (and abuse). But after 35 years, it’s fair to expect a three-door not to feel fresh. The road-going version of the Ford Sierra Cosworth RS500 is powered by an upgraded 2.0-litre turbocharged Cosworth engine producing 224bhp. Perhaps we shouldn’t be surprised. Fast Fords have been fetching big money for many years and the RS500 Cosworth is one of the most desirable modern classics you can buy. It’s also peak Cosworth.

Compare the chassis number on the logbook with the number on the VIN plate riveted to the slam panel and beneath a flap in the carpet beside the driver’s seat; it should read WF0EXXGBBE, followed by a series of two letters and five digits; these last seven characters should match the original engine number. Beware of missing stamps, although several Sierras have been welded over due to rotten inner sills. Any ground-off or home-stamped number is a special code that translates as ‘run away.’ Cossies are no longer supercars for the working man. Today you need a mortgage to buy a three-door and balls the size of melons to drive one as it’s intended.The Sierra’s engine bay is prone to corrosion and stress fractures. Look at the bulkhead, battery tray and inner wings, paying close attention to the suspension turrets, which are known to fold inwards and collapse; another warning sign is excessive negative camber on the front wheels. December 1982 –Sierra XR4i available, featuring 150bhp 2.8-litre Cologne V6 engine, sports styling with double rear spoiler and unusual three-door bodywork with split rear side windows. Because manufacturers had to build and sell 5000 Group A machines, these had to work as road machines. This worked well as a marketing tool – you really could watch the cars compete on Sunday, and then roll up at a dealer the day after and buy a model that looked pretty much the same.
