- Carry out a road test on traffic free roads in safe conditions following the highway code.

- Before proceeding with the test, check the inflation pressure of the two vehicles, restoring the values to the correct ones if they are found to be incorrect.

- Carry out the test on an uneven road surface, at a speed of 40 km/h to check the capacity of the suspension to absorb the stresses produced by small imperfections (suspension damping) with the consesquent acoustic repercussions inside the passenger compartment.

- Check the capacity of the suspension to absorb the stresses produced on very uneven surfaces with the consequent acoustic repercussions inside the passenger compartment: carry out the test at a speed of 40 km/h on a route that has a succession of man-hole covers.

- Check the rapid damping of any pitching produced by the irregularities of the road surface, carrying out the test at a speed of 50 km/h on a straight road with suitably spaced ridges/depressions, This type of test should always be carried out for comparison with a new vehicle or a reference vehicle of the same trim level and engine type, available in the workshop at the time of the test in question.

- At the end of the test in question, assess/rate the driving comfort of the vehicle in accordance with the enclosed table.

"The reference vehicle has a driving comfort default rating of 7".
