There’s a bit of a confusion surrounding who did what on Ford’s Escort Cosworth. Its chief exterior designer was Stephen Harper, while Ian Callum calls it his first major car design, adding that he created it with the help of fellow Royal College of Art graduate Peter Horbury. What’s for sure is that the Cossie’s iconic rear wing came from the head of yet another designer fresh out of college—Frank Stephenson. What’s more, Ford’s rally car was supposed to get a three-deck rear wing—inspired by the WWI Fokker Dr.I triplane—like the world had never seen before in automotive design.
Aerodynamic testing confirmed Stephenson was on the right track with that wing, but since the Escort Cosworth was a Sierra-based, all-wheel-drive car built by Karmann in Germany, the finance department decided to cut costs by simplifying the rear piece, and there wasn’t much a young designer could do about that.
With the twin-deck wing, the Escort Cosworth still produced enough downforce to win a total of ten WRC events, only for Ford to sell 7145 units until January 1996. That wasn’t a bad sales figure for a Group A homologation special, and for the 1997 and 1998 seasons, the platform even evolved into the Escort WRC. For 1999, Ford made the switch to the Focus WRC.
Two years ago, in an episode of Wheelers Dealers, an Escort Cosworth finally got the triple-deck wing Frank Stephenson envisioned in 1989. That 1995 car is for sale now, and here’s how the designer feels about that early idea today:
