Interlagos is usually synonymous with unpredictability, significantly due to the uncertainty surrounding the Brazilian climate, with rain presumably taking part in a task once more this weekend in line with latest forecasts. Nonetheless, by way of efficiency, the São Paulo circuit has to date met the pre-race expectations, with McLaren establishing itself as the favourite by securing your entire entrance row in dash qualifying.
Though Andrea Stella had instructed that Interlagos may be an unknown variable on this last a part of the season, figuring out different tracks as probably higher suited to focus on the MCL38’s strengths, Ferrari anticipated that sure features of Interlagos would pose higher 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 constraints of the entrance finish, that are extra evident at São Paulo. Nonetheless, this isn’t the one cause McLaren triumphed in Friday’s quick qualifying session; as in different rounds this season, McLaren’s sturdy total steadiness 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 capability to hold excessive speeds into the nook whereas remaining aggressive by 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 potential earlier than getting ready for the subsequent braking zone. Nonetheless, a lot of the deceleration section occurs in what known as a “mixed” method, the place the motive force is on the brake pedal whereas the automobile remains to be rotating, which significantly stresses the entrance finish. McLaren’s progress on this space over the previous yr is obvious.
Whereas climate stays the first unknown this weekend, sure efficiency parts mirror tendencies noticed all through the season, like Ferrari’s basic 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 totally lifting off, gaining a 7 km/h high velocity benefit in Flip 6.
Alternatively, Charles Leclerc can not totally open the throttle progressively, not like the McLarens, which, although slower to reapply the throttle, had been extra linear, gaining time in Flip 7 and on the quick stretch main into Flip 8 braking.
The primary chicane additionally exhibits a McLaren benefit. Throughout apply, 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 larger speeds on entry and thru the nook but in addition by offering each drivers with sturdy acceleration towards Flip 4, reaching a peak 3 km/h larger.
Taking a look at Flip 4 reveals one other subject for evaluation: missed alternatives. Though Oscar Piastri clinched pole by delivering within the decisive second, Norris misplaced out as a result of errors within the last 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, similar to Flip 4 the place he was in a position to brake late and carry excessive mid-corner velocity, was tangible, however lacking his second try weighed on his ambitions.
After qualifying, Charles Leclerc admitted that, whereas he gained’t concede defeat, McLaren stays the clear favourite for the weekend due to its balanced aerodynamics, together with a brand new medium-load wing, and mechanical setup that absorbs observe irregularities properly. In the meantime, after sturdy ends in Austin and Mexico, Ferrari has returned to going through 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, significantly with the dash in thoughts. Temperatures different 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 tough for groups to pinpoint the best window, a degree Carlos Sainz additionally talked about after qualifying. Ferrari believes it has a automobile extra targeted 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.
Purple Bull: Scuffling with bumps
Temperature, climate, and new asphalt all play a task. Interlagos was resurfaced this yr, 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 accomplished for this season appears to have worsened the issue. This caught groups off guard, forcing changes to setups, similar to elevating the experience top within the case of Mercedes and Purple Bull.
The Brackley crew has proven within the final two GPs that they’re aiming for the bottom potential experience top, to the extent that drivers regularly complained throughout apply concerning the automobile scraping the bottom. For Purple Bull, such points don’t swimsuit the traits of the RB20.
Purple Bull’s strengths and weaknesses are these seen all through the season: glorious efficiency in sooner 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.
Nonetheless, in relation to working the entrance finish and pushing the entrance tires, Purple Bull’s recurring steadiness points floor once more. Past peak speeds, Max Verstappen can not push into Turns 8 and 9 as a result of understeer, nor in Flip 4, the place Lando Norris’s margin over him is even higher than Oscar Piastri’s.
These components counteract the benefit in quick corners, compounded by the RB20’s tendency to undergo from bumps, resulting in a bouncy experience that reduces confidence. Purple Bull seems to have chosen a higher-downforce setup than its rivals, seemingly aiming to handle tire put on for the race or put together for potential rain in Interlagos. Notably, the Milton Keynes crew was among the many most energetic in FP1, operating excessive gas masses in an extended stint, clearly getting ready extra for the race than the dash.
