In March 1984 Ford management signed off on a drivable Ford Rallye Sport prototype – labelled the RS200. While features such as the front windscreen and rear lights from the earlier Sierra were borrowed, this vehicle was unique in the Group B series as it was the only bespoke model on the grid, not echoing anything on the road at the time.
The car packed a turbocharged Ford-Cosworth “BDT” engine capable of 336kW. Its best-ever finish was in 1986 at the WRC Rally of Sweden. The car is also infamous for a horrific accident, which claimed the lives of three spectators and injured many others at the Rally de Portugal.
