The model will be based on the new Focus ST, with ongoing development by Ford Team RS, the manufacturer’s specialist performance team, led by Jost Capito.
A concept version is expected in mid 2008, and full details are expected closer to the launch.
John Fleming, Ford of Europe's president and CEO said: "With two consecutive Manufacturers' World Rally Championship titles under our belt, the time is right to create a new Focus RS.
"We're not ready to confirm any of the technical details yet, Jost and his team have a lot to do to finalise the exact specification and styling.
"But make no mistake, I can assure you that ultimately the car we plan to launch will be worthy of wearing the coveted Ford RS badge."
