Why it matters
The RS500 was the evolution version of the Sierra RS Cosworth. Group A rules allowed an upgraded model once the 5,000 base cars existed, provided the maker sold 10 per cent of that number as road cars, hence 500. Hand-assembled and more powerful, it is described by the auction house as the ultimate 1980s Fast Ford.

02Production & history
Production
Every figure says what it counts.
| What is counted | Figure | Basis | Status |
|---|---|---|---|
| Total model productionhomologation cars ('500 off') | 5001,2 | Factory production | Factory reported |
Independent counts (e.g. engine and colour) are never combined into a calculated figure. Surviving examples are never presented as original production.
History
The RS500 was announced in July 1987. Each car started as a Sierra RS Cosworth three-door and was converted by Aston Martin Tickford, with an uprated engine closer to the competition unit, upgraded brakes and modified bodywork. A 1988 catalogue says all 500 were converted by Tickford Engineering.
Auction descriptions identify individual cars by their position in the run, such as number 215 and number 455 of 500, and one says 56 of the 500 were finished in White.

06Reference
Identification guide
How to tell an original from a replica or later conversion.
The RS500 has a 224bhp engine against 204bhp for the standard car, upgraded brakes and much larger spoilers and cooling ducts at the front and rear. Chassis numbers in the sources start WF0EXXGBBE with an engine number such as GG38672, and the cars are quoted by build number out of 500. The RS500 Registrar, Paul Linfoot, is named as an authority on originality.
