The Ford Sierra RS500 Cosworth Was A Serious Limited Edition

In the middle of the 1980s, Ford had plans to take part in the upcoming World Touring Car 

Championship. For this, they required a new car, hence the creation of the Sierra RS 

Cosworth. To homologate the Sierra for racing, Ford was required to produce 5,000 Sierras 

for the road. The "normal" RS Cosworth was already an exceptional car, but then the Sierra 

RS500 Cosworth appeared. Ford was given permission by a Group A racing Evolution 

regulation to create an improved RS Cosworth, but they were only allowed to produce 500 

of them, giving the vehicle the name RS500.The basic Sierra RS Cosworth and the RS500 

appear extremely similar to the untrained eye. There seem to be, however, slight variances. 

Ford fitted a new front splitter and a narrow aperture above the licence plate in the new 

front bumper to funnel more air into the engine compartment. At the back, they toughened 

up the rear wing and added a trunk lip spoiler as a second piece of aero. The chassis of the RS500 is almost identical to that of the standard 

 Sierra RS Cosworth, which is not a bad thing. Ford outfitted it with powerful springs, shock absorbers, and anti-roll bars so it could travel as quickly around a bend as it was straightaway.
