Citroen's 2017 WRC entrant is powered by a 1.6-litre turbocharged direct-injection four-cylinder engine. Thanks to the wider turbo restrictor permitted for the upcoming season, the engine is said to develop around 283kW of power (380hp).
With turbo pressure limited to 2.5 bars, torque output remains relatively stable at around 400Nm. Drive goes to all four wheels via a six-speed sequential transmission.
The all-wheel drive setup includes a centrally-controlled hydraulic differential, which allows the front and rear axles to rotate at different speeds. Citroen says that this permits torque transfer between axles to reduce understeer and slippage.
Although the new WRC car is based on the production C3 five-door hatchback, the rear passenger doors have been fused shut and no longer function.
Citroen has also increased the width of the car to 1875mm, the maximum allowed under the 2017 rules. The automaker has also cut the production body shell to allow the fitment of a roll cage, a transmission tunnel, new subframes for the chassis and suspension systems, and that huge composite-fibre rear spoiler.
The C3 WRC rides on new tilted spring-shock absorbers designed for increase wheel travel. The 2017 WRC car also uses different suspension geometries for tarmac and gravel tracks.
As per regulations, the C3 WRC weighs 1350kg with driver and navigator on-board.
According to Yves Matton, general manager of Citroen Racing, the goal in 2017 is to "win races in normal conditions, by beating our competitors". In 2018, though, "our goal is to bring home at least one of the world titles".
