The Citroen DS3 R3, a model set to make its rallying debut at the end of 2010, comes with a four-cylinder 1.6-litre THP (high pressure turbo) engine, which has been developed using the PSA production engine. Specific racing parts (air box, camshaft, pistons, connecting rods, exhaust and turbo systems, electronic unit, etc.) have been deployed to boost the car’s power to 210bhp. In addition to its overall power, special attention has been given to increasing the engine’s torque to improve traction, one of the key factors in delivering efficient driving performance. With 350Nm, the DS3 R3 engine offers unrivalled flexibility on the road.
One of the main innovations on DS3 R3 concerns its gearbox. For the first time, a customer-racing product has been fitted with a semi-automatic gearbox, which reduces the time spent changing gears and increases reliability. The electronic management system only authorises gear changes when the engine parameters allow it
