Ford's rally bred Sierra RS Cosworth bought supercar pace and handling into the grasp of the everyday public. Just 16,000 gave you performance to embarrass many so called supercars. Ford transformed the standard Sierra with handling and body modifications (including the memorable giant rear spoiler) then Cosworth, a famous name in racing circles, tuned the 2 litre turbo engine to a powerful 204bhp, with the potential to handle a lot more.

A limited run of 500 RS500 Cosworths appeared in 1987 with even more power and body modifications, then in 1989 the Sierra became the Sierra Sapphire 4 door saloon with a 4X4 following in 1990. The 'Cossie' will be remembered as possible the performance bargain of the 80's - if you could have afforded the insurance!
