GP Week : Issue 155
Monaco is usually a very specialised track, where the technical specifications of the cars differ hugely from those adopted on any other circuit of the calendar. This time, this basic principle didn’t change but we can say that many of developments introduced at Barcelona, were kept on the cars, and worked correctly even though in a completely different ‘environment’. This was the case for Ferrari, that kept almost all the changes introduced in Spain as aero package, notably those related to the rear diffuser, that we can correctly consider the most relevant element of the Ferrari improved performance in the last two races. Hence we decided to get a very close look to this element that is undoubtedly the most developed area of the car. It was interesting to note how deep was the study behind its refinement since the start of the season. The new version in fact features a cleaner design, in particular featuring rounded angles between the connection of the vertical fences and the main trailing profile. On the top edge is featured also an additional small profile whose function is to improve the extraction of the airflow from underneath the car, especially in the side sections of the diffuser close to the wheels. Very interesting also is the array of turning vanes with increasing vertical extension connected to the lowermost edge of the endplates. Their function is to dramatically reduce the turbulence generated by the rotating wheels in this area, which may interfere with the airflow exiting from the diffuser. We took also a close look at, not specifically another technical change, but an interesting feature , that plays a relevant role in Monaco. We took a look to the ballast placed inside the Lotus front wing. It was interesting to see that the amount of ballast placed there was adjusted many times, to perfect the front end behavior of the car. In such a twisty track in fact it is particularly important to have a very ‘sharp’ front end, especially in the very slow section to reduce the understeer that would cost hundredths of a second at each turn. In the Lotus front wing a deep housing is placed in the central front section of the front wing. Surprisingly, many of the technical steps forward made at Barcelona were retained on the unique Monaco layout!
