The secrets of Ferrari's brand-new floor explained

Ferrari's new floor brought to the Bahrain Grand Prix was initially at first planned to be a part of a major package it introduced at the Miami Grand Prix. 

The upgrade is an extensive intervention for the SF-25, with the focus starting on the leading edges where the vertical air-flow diverters have been modified, along with expanding the area and thus volume of the Venturi channels in the central sections. 

The diffuser has also been upgraded, with the throat area now characterised by a narrower V-shaped edge section compared to a more arched version in the first three races of the season. 

They are profound upgrades that have the twin objectives of not only increasing the downforce produced from the car, but also widening the operating window. 

Such is the extent of the upgrades, it is clear that it was not created in a rush - such as in response to Lewis Hamilton's post-Japanese GP comments - but the genesis can be traced back to after pre-season testing, multiple sources confirmed to RacingNews365.

The package is the result of a collaboration between the aerodynamics and vehicle dynamics departments at Maranello, with the below-par performances in the first three races the result of an imperfect integration between the aerodynamic concept and the vehicle dynamics.

How Ferrari's new floor works

Only in certain conditions did the two previously match together perfectly, but for the most part, they did not communicate as intended - as evidenced by the need for increased ride heights, which costs performance in the ground-effects era.

The new floor, in practice, is designed to vary the centre of aerodynamic pressure aligning it more closely with the centre of mass of the car.

This works by generating different pressures depending on the area of the floor, and is designed to prevent the rebound of the outgoing aerodynamic pressures, which can nullify the air-flow from underneath the car.

Hamilton himself has said he does not expect the upgrade to work miracles, but the upgrade is a concrete improvement for the SF-25, which should bring it closer into play with Mercedes, Red Bull, and McLaren.
