Assessment
The Smart ForFour 1.5 CDI 68hp is a 1.5L turbocharged diesel engine producing 68 BHP and 160 Nm from the factory. With a typical Stage 1 remap, output increases to approximately 92 BHP and 210 Nm — a gain of around 24 BHP (35%) and 50 Nm (31%).
This engine scores highly for remap suitability, with a balanced spread of gains across both power and torque — providing a noticeable improvement across the rev range. The tuning headroom is classified as high, based on the percentage gain available from the factory output.
Considerations: 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.
Fuel economy note: economy gains unlikely at full power; depends on driving style.
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.
