The Escort RS Cosworth was a homologation special built to qualify Ford for Group A of the World Rally Championship. Despite the Escort name, it's mechanically based on the Sierra RS Cosworth's platform, using a longitudinally mounted 2.0L Cosworth YB turbo engine and a permanent four-wheel drive system. Its most defining feature is the massive 'whale tail' rear wing, a direct result of aerodynamic requirements for the rally car.
Collectors prize the 'Cossie' for its raw, analog driving experience and its direct link to 90s rally glory. The first 2,500 cars, built for homologation, are the most desirable as they feature a larger Garrett T3/T04B hybrid turbo. Later 'small turbo' cars, fitted with a Garrett T25, are more street-friendly but less sought after by purists. Limited editions like the Motorsport and Monte Carlo also command premiums.
The market for the RS Cosworth is strong, with values appreciating consistently over the past decade. The average price hovers around $57,000, but there's a wide spread. Condition, mileage, and originality are key value drivers. Modified cars are common, but top prices are reserved for factory-spec, low-mileage examples, especially early 'big turbo' models which can exceed $100,000.
Buying Tips
- Check for rust thoroughly, especially in the floor pans, sills, battery tray, and around the sunroof opening.
- The Cosworth YB engine is robust but needs diligent maintenance. Look for a detailed service history and check for blue smoke, which can indicate worn turbo seals or piston rings.
- Verify originality. The first 2,500 'big turbo' models are more valuable. Many cars have been modified, which can affect value depending on the quality of the work.
- Inspect for signs of previous accident damage. Due to their performance, many were driven hard, so check for poor panel gaps and mismatched paint.
- Test the 4WD system. Listen for whining from the differentials and transfer case, as repairs can be expensive.
Prices range from around $12,000 for projects to over $102,000 for top-spec variants.
