The primary free apply session for the 2024 Components 1 British Grand Prix was probably one of many key moments for the rest of Ferrari’s season. The Maranello crew, for as soon as blessed by the climate, was capable of full an intensive comparative work program between the 2 automobiles. Charles Leclerc took to the observe with the extra up to date model of the SF24, whereas Carlos Sainz ran with the aerodynamic configuration that preceded on the Barcelona bundle.
We’ve got already defined why this second is especially delicate for the Maranello crew, and clearly, the necessity to rapidly discover a resolution to the rising issues is such that some free apply classes have to be sacrificed to gather information from the observe. Though the lap packages weren’t completely equivalent between the 2 drivers, it’s potential, by making a cautious comparability and weighing the collected information, to attract some conclusions even with solely the info obtainable to us, since some tendencies are sufficiently macroscopic to be observed even with out the small print from load cells and varied sensors on the automobiles.
Visually, the bouncing on Charles Leclerc’s automobile within the quick sections was notable
To begin with, it have to be said that even from the easy onboard pictures, some variations have been simply seen to the bare eye, foremost amongst them the aerodynamic bouncing, which was abundantly current on Charles Leclerc’s automobile and virtually absent on Carlos Sainz’s. The impression is that in corners with a reasonably fixed radius, the phenomenon is current however much less impactful, however in your complete central sector, the distinction in automobile habits is obvious, with the rear finish tending to grow to be unstable in the midst of the curve, exactly the place the bouncing turns into extra pronounced. The impression, due to this fact, is that one of many causes the Maranello engineers haven’t been capable of predict the recurrence of the phenomenon or see it in wind tunnel simulations is that there’s a robust dynamic part of the automobile that triggers it, whereas underneath steady circumstances, the issue loses no less than an order of magnitude. The bumps in Barcelona and the undulations in Austria evidently acted as catalysts for triggering the bouncing, whereas the very easy asphalt at Silverstone helps the SF24 defend in opposition to the phenomenon, till the central sector is reached the place the violence of Copse first, and instantly after the continual load switch of the Maggots-Becketts-Chapel sequence, places the system in evident disaster. The info broadly confirms what has been noticed to this point. We took the readings of the most effective lap on arduous tires from each Ferrari drivers and, as typical, in contrast them.
Trying on the telemetry information from FP1, the primary premise is clearly that the 2 drivers accomplished the lap with considerably totally different Energy Unit mappings, with Carlos Sainz capable of push virtually to the utmost degree of the engine (evidently to gather information underneath excessive circumstances). That is evident from the primary braking at flip 3, after which all through the exit of flip 5 onto the straight in direction of Brooklands and Luffield. Within the latter flip, flip 7, it’s noticeable that at medium-low speeds, in an extended nook with a reasonably fixed lateral load, the up to date model of Charles Leclerc’s SF24 produces a better quantity of aerodynamic load than Carlos Sainz’s Ferrari, confirming what Ferrari itself said on the eve of the Spanish Grand Prix, that the brand new bundle introduced a rise in load even at medium-low speeds.
Nonetheless, from the exit of Luffield onwards, troubles start for the Monegasque driver and for the updates on the Ferrari automobile. At Copse, the Monegasque driver passes by means of 5 kilometers per hour slower than his teammate and lifts his foot off the accelerator considerably greater than Carlos Sainz, after which on the entrance of Maggots, the toughest stretch begins, with the Spaniard affected by much less load at Becketts however having a lot better stability of the automobile, a lot in order that the passage at Chapel onto the Hangar Straight sees the Spaniard passing by means of 9 kilometers per hour sooner than the Monegasque. Within the subsequent flip, Stowe, nevertheless, the load of the up to date SF24 reappears, contemplating that the passage by means of the difficult flip 15 of the English observe is a reasonably clear indicator of the aerodynamic load ranges of the automobiles. As soon as once more, a easy observe and a nook with a delicate, fixed radius decelerate the onset of aerodynamic bouncing and permit Charles Leclerc to go 6 kilometers per hour sooner, then coming into the final stretch and the ultimate low-speed chicane, the place mechanics take priority over aerodynamics, and as soon as once more Carlos Sainz finds better efficiency.
The habits at turns 16-17 (but additionally beforehand seen at flip 4) appears to point that the difficulties resulting from aerodynamic bouncing power a non-ideal mechanical setup in an try to make the phenomenon no less than manageable, and due to this fact Carlos Sainz’s automobile seems to have smoother and extra pure passages in significantly gradual sections. It’s clear that Ferrari has an issue to resolve, and this session confirmed that work at Maranello is actively underway. We’ll see if the climate, threatening rain, will permit a clear second session, how Ferrari will benefit from it to attempt to advance of their understanding of the bundle, and the way the Maranello crew will work to discover a resolution.
