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.

R3… what doest it means? R3 also for for proton… after this can la proton compete in this segment.. because proton will have 1.6 turbo engine… next year…
this is what i call a ‘pocket rocket’
Car look so cute, not look muscular like previous Citroen Xsara & Saxo.
Klau proton bawak kluar R3 selepas citroen, mesti ada yg cakap proton tiru citroen kan?
Looks like the entry level series has started to drop the normal aspirated engine formula, in favour of turbocharged engine. S1600 is no more….
Proton should pattern R3, jangan jadi macam GTi, once VW pattern GTi satria cannot use it anymore..
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.
Proton / Perodua should design or built something like this and sell around RM70k….
woohoo! Now i get bigger shot at the mini and the golf along orchard. Though i don’t plan to race with them
damn freaking nice car~ much better than mini cooper S~ !!
paul.. when you say production cars.. you meant those in Europe or worldwide? cause mine really don’t feel like a 156 bhp car.. by DS3 seems to be souped up from the looks only leh..
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.
