Interlagos is usually synonymous with unpredictability, notably due to the uncertainty surrounding the Brazilian climate, with rain probably enjoying a job once more this weekend based on current forecasts. Nevertheless, by way of efficiency, the São Paulo circuit has to this point met the pre-race expectations, with McLaren establishing itself as the favourite by securing the whole entrance row in dash qualifying.
Though Andrea Stella had prompt that Interlagos could be an unknown variable on this closing a part of the season, figuring out different tracks as doubtlessly higher suited to spotlight the MCL38’s strengths, Ferrari anticipated that sure facets of Interlagos would pose larger challenges for the SF-24 than the final two races.
At Austin and Mexico Metropolis, in addition to at Singapore and Baku, different circuits the place the Maranello automobile carried out properly, there aren’t as many lengthy corners that expose the restrictions of the entrance finish, that are extra evident at São Paulo. Nevertheless, this isn’t the one cause McLaren triumphed in Friday’s brief qualifying session; as in different rounds this season, McLaren’s sturdy general stability as soon as once more emerged as a key benefit for the MCL38.
Balanced McLaren, Ferrari’s weaknesses resurface
As an example, evaluating Oscar Piastri’s pole lap with Charles Leclerc’s, who will begin third tomorrow, the primary noticeable issue is the Woking automobile’s potential to hold excessive speeds into the nook whereas remaining aggressive by way of the mid-corner.
Flip 8 braking is essential for setting a quick lap, as drivers come from the high-speed Flip 7 sequence and attempt to straighten the automobile as rapidly as doable earlier than making ready for the following braking zone. Nevertheless, a lot of the deceleration section occurs in what is named a “mixed” method, the place the motive force is on the brake pedal whereas the automobile continues to be rotating, which notably stresses the entrance finish. McLaren’s progress on this space over the previous 12 months is clear.
Whereas climate stays the first unknown this weekend, sure efficiency parts mirror developments noticed all through the season, like Ferrari’s normal lack of competitiveness in very quick corners. This problem resurfaced at Interlagos, as seen in Turns 6 and seven. An fascinating level is the distinction in method in comparison with McLaren drivers: Charles Leclerc can anticipate throttle reapplication with out absolutely lifting off, gaining a 7 km/h high pace benefit in Flip 6.
Alternatively, Charles Leclerc can’t absolutely open the throttle progressively, in contrast to the McLarens, which, although slower to reapply the throttle, have been extra linear, gaining time in Flip 7 and on the brief stretch main into Flip 8 braking.
The primary chicane additionally reveals a McLaren benefit. Throughout follow, Ferrari tried to tweak its method with its drivers, particularly in how they braked into Flip 1, which affected the setup for Flip 2. Right here, the MCL38 proved very efficient, not solely by reaching increased speeds on entry and thru the nook but additionally by offering each drivers with sturdy acceleration towards Flip 4, reaching a peak 3 km/h increased.
Flip 4 reveals one other matter for evaluation: missed alternatives. Though Oscar Piastri clinched pole by delivering within the decisive second, Norris misplaced out because of errors within the closing moments, squandering potential that might have positioned him forward of his teammate. Whereas the Australian’s tempo was sturdy, Norris’s benefit in sure observe sections, comparable to Flip 4 the place he was capable of brake late and carry excessive mid-corner pace, was tangible, however lacking his second try weighed on his ambitions.
After qualifying, Charles Leclerc admitted that, whereas he received’t concede defeat, McLaren stays the clear favourite for the weekend because of its balanced aerodynamics, together with a brand new medium-load wing, and mechanical setup that absorbs observe irregularities properly. In the meantime, after sturdy leads to Austin and Mexico, Ferrari has returned to dealing with acquainted weaknesses, although minor enhancements are evident. Excessive-speed and lengthy corners proceed to problem the SF-24 over a single lap.
One other key problem is tires, notably with the dash in thoughts. Temperatures assorted considerably on Friday, with observe temperatures dropping from over 50°C throughout FP1 to only over 30°C by qualifying as clouds rolled in. With such giant fluctuations, it turns into troublesome for groups to pinpoint the perfect window, some extent Carlos Sainz additionally talked about after qualifying. Ferrari believes it has a automobile extra centered on tire administration than pure efficiency. In FP1, they examined stints that appeared extra suited to the dash than Sunday’s race, however their tempo was nonetheless aggressive.
Crimson Bull: Fighting bumps
Temperature, climate, and new asphalt all play a job. Interlagos was resurfaced this 12 months, however paradoxically, the brand new floor is even bumpier than earlier than. The Brazilian observe has at all times been difficult on this respect, however the work completed for this season appears to have worsened the issue. This caught groups off guard, forcing changes to setups, comparable to elevating the trip peak within the case of Mercedes and Crimson Bull.
The Brackley staff has proven within the final two GPs that they’re aiming for the bottom doable trip peak, to the extent that drivers continuously complained throughout follow in regards to the automobile scraping the bottom. For Crimson Bull, such points don’t swimsuit the traits of the RB20.
Crimson Bull’s strengths and weaknesses are these seen all through the season: wonderful efficiency in quicker corners, particularly in Turns 6 and seven, the place Max Verstappen carries a ten km/h benefit, showcasing the effectiveness of the RB20’s aerodynamics in these sections.
Nevertheless, on the subject of working the entrance finish and pushing the entrance tires, Crimson Bull’s recurring stability points floor once more. Past peak speeds, Max Verstappen can’t push into Turns 8 and 9 because of understeer, nor in Flip 4, the place Lando Norris’s margin over him is even larger than Oscar Piastri’s.
These elements counteract the benefit in quick corners, compounded by the RB20’s tendency to undergo from bumps, resulting in a bouncy trip that reduces confidence. Crimson Bull seems to have chosen a higher-downforce setup than its rivals, possible aiming to handle tire put on for the race or put together for potential rain in Interlagos. Notably, the Milton Keynes staff was among the many most lively in FP1, operating excessive gas masses in an extended stint, clearly making ready extra for the race than the dash.
