This is the new Citroen DS3 R3, built to the FIA’s new Group R3T regulations. It features he same structural design and appearance as the production model, with the production steel body shell reinforced by a welded, multi-point roll cage.

The engine is the BMW PSA Prince 1.6 litre THP engine modified with uprated parts such as a racing air box, cams, pistons, conrods, exhaust system, turbo and ECU, helping boost power up to 210hp (with 350Nm torque) from the usual 156hp to 175hp range found in the production cars. The oil sump has been modified and fitted with a composite partiten to both increase ground clearance and avoid oil surges during long corners.

The engine is mated to a 6-speed sequential racing gearbox with paddle shifts, the same model in the C4 WRC. A clutch is still present but is only required to start from standstill – afterwards its just flicking the pedal forward to downshift and pull them back to upshift.

The car will be sold by Citroën Racing in kit and ready-to-race versions, so privateer teams can start buying it. The base car is a DS3 THP 150 and there’s a whole new list of 500 new parts required to turn it into the DS3 R3 – you can find this list after the jump.
