The Ford Focus RS WRC is a car built for the Ford World Rally Team by Ford Europe and M-Sport and based on the Ford Focus Climate 2-litre production hatchback, developed to compete in the World Rally Championship. The RS stands for Rallye Sport and the WRC for World Rally Car, the car's FIA specification. The Focus RS WRC was in competition from 1999 to 2010, winning 44 world rallies and two manufacturers' world titles (2006 and 2007). It was replaced by the Ford Fiesta RS WRC.

Like all contemporary World Rally Cars, the car is heavily modified from the production version, with which it shares only the basic shape and some parts of the bodyshell. The car features four-wheel drive, rather than the front-wheel drive of the road car. The engine used in the 2007 Focus WRC is based on Ford's 2.0 Litre Duratec from other models in the Focus range as rallying rules do not permit the standard 2.5-litre engine of the Focus ST or road going RS. As with most rally cars, the 2.0-litre engine is heavily modified and performance was increased using a turbocharger. The 2009 Ford Focus RS WRC uses a Ford 1998cc Pipo built I4 Duratec WRC engine (four cylinders, 16 valves, bore 85 mm and stroke 88 mm), Pi electronic engine management system, Garrett turbocharger (with required 34 mm inlet restrictor), air intercooler, and a catalytic converter.

The car's transmission is a permanent four-wheel drive with an M-Sport designed active centre differential, Pi electronic differential control units, M-Sport/Ricardo five-speed sequential gearbox with electro-hydraulically controlled shift and an M-Sport/Sachs multi-disc carbon clutch.^[1]
