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.
Ferrari says its 2023 F1 car won’t be revolutionary, at least visually, 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 important technological innovations on the floor that could increase the competitiveness of F1 cars, especially caused by regulatory changes, also Ferrari’s F1 2023 car, which is under development as design code “675”, Paolo Filisetti explains that he will show the distinctive elements in the visible part.
Comparing F1-75 and 675, the side profiles are different. The shape of the sidepods maintains the same “sculpted” profile at the top, with a wider grille for heat dissipation, but more importantly the rear “coke bottle” section is moved further forward and the rear sidepods are significantly narrowed towards
At the same time, the low profile of the sides creates a sort of channel which 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 certain sense it is a natural evolution of the previous project, not completely destroying the internal packaging of the cooling system, but a different arrangement of the deformable structures on the sides of the passenger compartment.
In a top-to-bottom comparison, it’s clear how the 675’s engine cover at the rear features. This choice is the result of the reduction of the rear volume of the sides and of the slits placed in the upper concave profile. The increased horizontal rear vent allows the heat exchange to remain constant despite the smaller lateral volumes.
The chassis, in fact, differs significantly from its predecessor in the lower sections of the cockpit sides and in the fuel tank area, which is said to maintain a precise correspondence only at the engine pick-up point. The work to evolve the position of the interior involves a complete modification of the gearbox, allowing the adoption of a diffuser characterized by a 10 mm higher junction to the venturi channel.
Although the suspension has been modified, the rear suspension has a different positioning of the elements within the gearbox to allow for a different floor design in this area.
At the power unit level, the evolution of the 066/7, which had reliability problems related to the turbocharger and MGU-H, has been reduced to maximum filling of the combustion chamber and effective TJI (Turbulent Jet Injection) propagation of the internal front flame. . ) depended on research to improve injection system efficiency.
The data from the long bench test of the new engine (admitted for reliability purposes) were clearly encouraging. There’s also a story that horsepower has increased by about 30hp over the previous generation, while keeping it inconspicuous.
