ROAD TEST FOR COMFORT EVALUATION

Check 44A

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.

Also check the conditions of the wheel rims making sure they are not distorted or broken, replacing them if any faults are found.

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 by large imperfections and the consequent acoustic repercussions inside the passenger compartment, carry out the road test at a speed of 40 km/h over a route that has a series of pot-holes.

Check the rapid damping of any pitching produced by the irregularities in the road surface, carrying out the test at a speed of 50 km/h on a straight road with suitably spaced humps and holes.

This type of test should always be used for comparison with a new vehicle or 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.
