Correct answer
Approximately 5%, as guidance.
Around 5%, as an indicative figure published by the DGT. The actual increase depends on the vehicle, route, speed and other conditions; it is not a fixed law per 100 kg. Additional weight does not necessarily mean weight above the MAM: consumption can increase with a legal load. Do not exceed authorised masses or seating capacity and avoid unnecessary weight.
