How is the road tax calculated?
Unlike the registration tax, the road tax depends neither on the car's age nor on its CO2 emissions, but on its fiscal horsepower. This is determined by the engine size (box P.1 of the registration certificate), according to the official table below.
For a hybrid car, the engine size of the combustion engine counts.
