The forth and final incarnation of the Sierra Cosworth was built to overcome the short comings of 2wd in Rally competition which since the introduction of the Audi Quattro in 1980 had became dominated by four wheel drive machines. 12,250 of the Sierra RS Cosworth 4×4’s were built in Genk, Belgium.
The Cosworth 4×4 was timed to coincide with a minor facelift to the Sierra range in 1990, powered by either 224 hp Cosworth YBG with catalytic converter or YBJ motors, without the converter, coupled to a Ferguson patented all wheel drive transmission. The road going variant is distinguished by the return of the bonnet louvre’s seen on the first two RS Cosworth variants and discreet 4×4 badges on the front wings. Note also the return of the Sierra RS Cosworth name to the boot / trunk lid as on the original 3 door version.
Unfortunately due to it’s size compared to the competition which included the pint size Lancia Delta & Mazda 323 hatchbacks and Toyota Celica Coupé, all with four wheel drive, none of the four Sierra RS Cosworth variations ever won a World Championship Rally, though Francois Delecour managed a couple of 3rds in Monte Carlo and Spain driving the Cosworth 4×4 in 1991..
