The car, which is built and run by former rally driver Malcom Wilson's M-Sport operation in the UK, is based on the 2017 Ford Fiesta and therefore replaces the Ford Fiesta RS WRC. The rally car is a three-door and uses a 1.6-litre Ecoboost engine that produces 380bhp and 332lb ft of torque, thanks to the use of a larger 36mm restrictor, as per new 2017 regulations.
The engine is mated to a new six-speed sequential gearbox with a hydraulic shift that sends drive to all four wheels via a multi-disc clutch and an active centre differential – a new part that enables drivers to adjust the torque split between the axles while the car is running.
Since the new WRC car is based on the next-generation Fiesta, the chassis is all-new. However, M-Sport said it has already completed nearly 4000 miles of testing in the run-up to the new season, which kicks off at the Monte Carlo Rally in the last week of January.
