248 F1 UPDATES FOR SAN MARINO
Part of extensive changes to the Ferrari at Imola, designed to improve performance and overall balance. New endplates sport a flat upper profile instead of the previous sculpted one, with a horizontal triangular fin at the rear (1). This improves airflow management close to the wheels. The additional fins on either side of the nosecone (2) now have a wing-shaped profile, which improves airflow efficiency between the chassis and the tyres. All these changes improve the quality of the airflow passing underneath the car, which is then extracted by the rear diffuser.
Part of the revised aero package for Imola. Though the boards themselves look little different, the changes are in the cross sections of the winglets attached to them. The lower winglet has been slightly enlarged to better manage airflow passing under the car. The upper one is also slightly bigger, helping to split the airflow passing close to the sidepods. This cuts the vortices around the sidepod entrance, allowing more air to enter, hence improving the car's cooling capabilities.
Since its introduction in Bahrain, the protruding outer lip (in red) on Ferrari's wheel rims has been the subject of much discussion, with rivals questioning whether it constitutes an illegal moveable aerodynamic device - the movement being the wheel's rotation. Ferrari say the lip is a functional part of the air intake system for brake cooling and that its profile remains the same, regardless of whether the wheel is moving - hence it is not effectively 'moveable'. Ferrari's brake cooling system has two main parts - an inner drum (in yellow) where cool air (blue arrows) enters, and an outer part where heat from the brakes (red arrows) is expelled.
