Ferrari says its 2023 F1 car will essentially continue in the direction of this season’s F1-75, but RacingNews365.com technical analyst Paolo Filisetti says it was actually inspired by Red Bull. Explain that it has evolved.
Ferrari says its 2023 F1 car won’t be revolutionary, at least on a visual level, compared to the F1-75. However, this does not mean that the aerodynamic concept duplicates the previous one, but quite the opposite, explains Paolo Filisetti.
Bearing in mind that there are major technological innovations on the floor that could increase the competitiveness of F1 cars, especially caused by regulatory changes, even Ferrari’s 2023 F1 car, which is being developed as design code ‘675’ Paolo Filisetti explains that it will show the distinctive elements in the visible part.
Comparing the F1-75 and 675, the side profiles are different. The sidepod shape maintains the same ‘sculpted’ profile at the top, with a larger grille for heat dissipation, but especially the rear ‘coke bottle’ section is pushed further forward and the sidepods are rearward is significantly narrowed towards
At the same time, the low profile of the sides creates a kind of channel that follows the ‘double floor’ principle brilliantly interpreted in the Red Bull RB18, making the step between the vertical section and the floor more visible. In a way, it is a natural evolution of the previous project, not completely destroying the internal packaging of the cooling system, but a different arrangement of deformable structures on the sides of the cockpit.
In a top-down comparison, it’s clear how the 675’s engine cover characterizes in the rear section. This selection is a result of the reduction of the rear volume of the sides and the slits placed in the upper concave profile. The increased horizontal rear vent allows the heat exchange to remain constant despite the smaller side volumes.
In fact, the chassis differs significantly from its predecessor in the lower sections of the cockpit sides and in the fuel tank area, which purportedly maintains precise correspondence only at the engine pick-up point. Work to evolve the position of the internals involves a complete modification of the gearbox, allowing the adoption of a diffuser featuring a 10mm higher junction to the venturi channel.
Although the suspension has been modified, the rear suspension has different positioning of elements within the gearbox to allow for a different floor design in this area.
In terms of the power unit, the evolution of the 066/7, which had reliability issues related to the turbocharger and MGU-H, was reduced to maximum filling of the combustion chamber and effective propagating TJI (Turbulent Jet Injection) of the internal flame front. ) depended on research into improving the efficiency of the injection system.
The data from the long test bench test of the new spec power unit (allowed for reliability purposes) was clearly encouraging. There is also a story that the power has increased by about 30bhp from the previous generation while keeping it inconspicuous.
