The Ford Fiesta RS WRC is the World Rally Car built for the Ford World Rally Team by Ford Europe and M-Sport for use in the World Rally Championship2011–2016. It is based upon the Ford Fiesta road car, and replaced the Ford Focus RS WRC, which competed in various versions since 1999. It is also built to the new World Rally Car regulations for 2011, which are based upon the existing Super 2000 regulations, but is powered by a turbocharged 1.6-litre engine (1.6 L turbo Ford EcoBoost engine[2]) rather than the normally aspirated 2-litre engine found in Super 2000 cars. M-Sport and Ford introduced a Super 2000 version of the Ford Fiesta at the beginning of 2010, which forms the base of the WRC car.
In 2012, the RRC version of the Fiesta was launched to comply with the regional rally rules of the FIA; it is basically a Fiesta RS WRC, only with an S2000-specification rear wing, a slightly different front bumper, a lighter flywheel and a 30mm restrictor instead of a 33mm one found in the WRC variant. The Fiesta's with RRC specification can be converted to WRC specification in 6 hours.[4]
In Rally Finland 2014 M-Sport launched a facelifted version of the Fiesta RS WRC. Despite the change on the front of the car, it's still the same under the bonnet. M-Sport later revealed the 'Evolution' version would come in 2015.
Before Rally Portugal 2015, M-Sport launched the 'Evolution' specification of the Fiesta RS WRC. Unlike the first version's engine which was built by Pipo Motors, the new Fiesta RS WRC's engine is completely built by M-Sport, with technical support from Ford. The car has also undergone a full redesign under the bonnet with further developments to the cooling package, transmission, electronics, wiring harness and differentials.
