The Abu Dhabi Grand Prix is not only the last race of the World Championship, but also the last opportunity to test solutions on the track to be integrated into the 2023 projects. Indeed, it is common practice among all the teams to instrument the cars with aero sensors to gather final pieces of data on track before the off season. Ferrari carried out an important data collection in Friday practice with Carlos Sainz, whose F1-75 had been heavily instrumented with an intricate network of sensors mounted on rakes behind the rear wheels. The function is to measure the pressure of the air flow leaving the diffuser and behind the rear wheels. The lower side has been modified in the area in front of them, with the function of managing turbulence in the area between the inside of the rear wheels and the diffuser in a different way from what happened during the season. These are not radical changes, but they are capable of increasing the effectiveness of the underbody by generating more downforce and reducing drag.
