Gearbox tuning for your Smart City

Gearbox software needs to match the engine calibration, torque curve and transmission fitted to this exact generation and powertrain.

• Confirm gearbox type and software support before booking.
• Match shift strategy and torque limits to the engine tune.
• Use the saved garage vehicle to keep engine and gearbox work together.

Why this is vehicle-specific

The selected vehicle is Smart City 450 with the 0.8 CDi 45HP Diesel powertrain. Saving it to My Garage lets future pages use the exact vehicle context instead of asking the customer to start the lookup again.
