Matthew Wilson will drive a factory Ford Fiesta RS WRC for the first time in public at tomorrow's Rallyday event at Castle Combe.
Wilson last drove at the demonstration event in 2009, and said he is looking forward to returning to the Wiltshire track.
He will be joined by other top British drivers Kris Meeke and recently crowned Rally America champion David Higgins.
"As a British driver I always like to support events such as Castle Combe, but it can be difficult with a busy schedule," said Wilson, who usually drives a Stobart Ford in the World Rally Championship. "I can't wait to entertain the spectators with our car."
The Fiesta will be one of the factory cars, previously driven by Mikko Hirvonen and Jari-Matti Latvala.
