The Ford Fiesta WRC is a World Rally Car built by the M-Sport World Rally Team for use in the World Rally Championship starting in 2017. It is based upon the 2017 Ford Fiesta road car, and replaced the Ford Fiesta RS WRC, which competed between 2011 and 2016. It was built to the fourth generation of World Rally Car regulations that were introduced in 2017.
