The Circus from the F1 go back to United States. Sixth appointment of the competitive campaign 2024 interesting in several respects. First of all, for the second time in the championship, he will be present there Sprint Raceparticular format which overturns the classic weekend: two races, a 100 km mini and the usual Sunday one, two qualifications, Sprint Shootout And Qualifying and just one free practice session. Sixty minutes in which the teams will have to fine-tune the cars. The double parc fermé will allow you to change the setting of single-seaters on Saturday, a “wild card” that can help if used properly.
The layout from the Florida it unrolls near the imposing one Hard Rock Stadium, a truly demanding track from a motoring point of view, taking into account the various high-speed sections. For this simple reason, the compromise development will not be at all easy to identify, essential to calibrate the equation that in the current body of legislation regulates the performance from the wing car: load vs aerodynamic efficiency. Also fundamental will be the grip mechanical in the guided sections and the speed in changes of direction. As far as vertical thrust is concerned, medium load is the most suitable choice
At the motorsport level, a considerable push will be needed from the power unit, put under pressure by large accelerations. The Miami International Circuit has a total length of 5412 meters. There are 57 laps to go to clear a total distance of 308,326 km and cross the finish line. Nineteen curves, 7 on the right and 12 on the left. Pirelli brings the core range of tyres: Pirelli C2 Hard, C3 Medium And C4 Soft. One or two stop strategy both possible.
Miami demanding: aero efficiency, load stability and traction
The first sector is very demanding on an aerodynamic level. Lots of vertical thrust needed, where drivers will have to be good at managing sudden shifts in load and understeer. Turns 4, 5 and 6, fast and supported, added to the variable radius hairpin towards turn 8, represent an important challenge where the stability of the rear is crucial. The T2 of the American track takes shape with the extension of approximately 1.5km. Treatment full throttle which leads to the braking of 11. Optimal level of Drag (rolling resistance) and system efficiency DRS are fundamental, as is the ability to discharge the approximately 1000 HP generated by the vehicles to the ground power unitfrom the endothermic/hybrid system combination.
The second part of T2 it involves a series of medium-low mileage curves, where mechanical grip and balance of the rear axle must be perfect. The ability to “cut” curves using curbs is important. The last section of the track includes another straight line, 1.2km, which will once again highlight the speed qualities of the single-seaters, a section of the circuit which favors overtaking. Turn 17 is a very demanding braking section that produces a deceleration of around 260 km/h in just 120 metres. The apex point is postponed to bring forward the acceleration to the goal line.
Ferrari uses Red Bull, aeromechanical interaction to optimize performance
The team Of Maranello must redeem itself after the China. The two SF-24 they showed a very stable performance in large-radius and stance curves. The redheads have an excellent level of downforce but at the same time they reveal a lower competitiveness, in the slow sections, compared to the 2023. The Italian technicians tried to stiffen the single-seater to have greater load stability from the bottom, an aspect which from a mechanical point of view created a loss of grip.
Ferrari will have to “construct” the round in a different way compared to previous editions of the Miami GP, when he dominated in the guided areas by optimizing the fastest sections. If in the first sector the SF-24 will be able to maximize the return, the “weight” of the slow traits in the economy of the round will be less. However, the Ferrari drivers will try to preserve the rear axle to avoid slipping which, as a consequence, would significantly reduce performance. At the rear, the usual wing seen in this first part of the world championship will be used. Technicians and pilots, through fine-tuning, will have to find the right balance between EOSS (speed at the end of the straights) and vertical thrust.
Although a Shanghai the value of these two parameters was good but was nullified by the poor activation of the tires which, as we know, destroyed the competitiveness of the Ferrari in the race, especially in the second stint with the Hard. The load adjustment around the optimal value, estimated from simulations and previous experience of teamwill be achieved through the interaction between the rear wing and the beam winga small aerodynamic appendage that acts as a real extension of the diffuser, with which the right interaction is sought to offer the right level of downforce at the rear.
Mechanically speaking, Ferrari will move the balance towards the rear. A necessary operation which, however, considering the distinctive features, it could put Modena cars in difficulty. We will therefore try to avoid excessive excursions of the bottom which reduce stability. Via the simulator driver-in-the-loopItalian engineers studied setup dissimilar compromises. Configurations that will be tested during the first and only free trials, to find the right balance between the various technical factors mentioned above. Ultimately the much talked about tire topic.
Ferrari he doesn’t know how to turn on properly compound showing a tendency to put a lower amount of energy into the tire than the competitor. An aspect that in eastern countries is more burdensome due to the low temperatures. Problem that a You love me it will not make a presence, as the mercury column will rise to 28 degrees. The team however, he made several resolutions warm-up-strategy aim for the out lap. Measure to better manage the hysteretic cycle of the tires, determined by temperature and frequency stress entered. Curve 3 and 6 choices from prancing Horse to adopt the strategy relating to tire management.
