Assessment

The Mercedes-Benz C 180 CDI 120hp is a 2.1L turbocharged diesel engine producing 120 BHP and 300 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 200 BHP and 440 Nm — a gain of around 80 BHP (67%) and 140 Nm (47%).

This engine scores highly for remap suitability, with gains weighted towards peak power — the improvement is most noticeable at higher RPM. The tuning headroom is classified as high, based on the percentage gain available from the factory output.

Considerations: High tuned torque: check transmission torque capacity and service history.. Large torque increase: drivetrain condition (clutch/gearbox) becomes more important at this level.. Older diesel: injector, turbo and intake condition can affect results; ensure maintenance is up to date.

All figures shown are typical estimates based on aggregated Stage 1 data for this engine variant. Actual results depend on vehicle condition, mileage, and the chosen tuning method. We recommend discussing your specific vehicle with a qualified remap professional.
