Citroen DS3 R3 rally car for FIA Group R3T regulations

Citroen DS3 R3 rally car for FIA Group R3T regulations

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.

    Looks like the entry level series has started to drop the normal aspirated engine formula, in favour of turbocharged engine. S1600 is no more….

    R3 does not mean Proton’s R3 Division but refers to the FIA Group R regulations . The Citroen DS3 here is built to R3 category regulations. ( between 1.6- 2.0 engine cc )

    Malaysia is not a signatory to the international trademark / copyright agreement. which is why malaysians can still buy exact copycat rip-offs of R3 products and badges and there is nothing Proton R3 can do about it.

    wonder how much citreon will be selling the “R3T” kit. renaults R3 kit for the clio costs around euro50,000 which doesnt include the price of the car.

    but i think the price wont differ much as FIA probably set a ceiling price.
