Interlagos is usually synonymous with unpredictability, significantly due to the uncertainty surrounding the Brazilian climate, with rain probably enjoying a job once more this weekend in response to current forecasts. Nevertheless, by way of efficiency, the São Paulo circuit has so far 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 urged that Interlagos is likely to be an unknown variable on this last a part of the season, figuring out different tracks as doubtlessly higher suited to spotlight the MCL38’s strengths, Ferrari anticipated that sure points of Interlagos would pose better 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 automotive carried out nicely, there aren’t as many lengthy corners that expose the constraints of the entrance finish, that are extra evident at São Paulo. Nevertheless, this isn’t the one motive McLaren triumphed in Friday’s brief qualifying session; as in different rounds this season, McLaren’s robust total steadiness as soon as once more emerged as a key benefit for the MCL38.
Balanced McLaren, Ferrari’s weaknesses resurface
As an illustration, evaluating Oscar Piastri’s pole lap with Charles Leclerc’s, who will begin third tomorrow, the primary noticeable issue is the Woking automotive’s means to hold excessive speeds into the nook whereas remaining aggressive by means 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 automotive as shortly as doable earlier than making ready for the subsequent braking zone. Nevertheless, a lot of the deceleration part occurs in what known as a “mixed” method, the place the driving force is on the brake pedal whereas the automotive remains to be rotating, which significantly 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 tendencies noticed all through the season, like Ferrari’s common lack of competitiveness in very quick corners. This challenge resurfaced at Interlagos, as seen in Turns 6 and seven. An attention-grabbing 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 prime velocity benefit in Flip 6.
Alternatively, Charles Leclerc can not totally open the throttle progressively, in contrast to the McLarens, which, although slower to reapply the throttle, had been extra linear, gaining time in Flip 7 and on the brief stretch main into Flip 8 braking.
The primary chicane additionally exhibits 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 greater speeds on entry and thru the nook but in addition by offering each drivers with robust acceleration towards Flip 4, reaching a peak 3 km/h greater.
Taking a look at Flip 4 reveals one other matter 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 would have positioned him forward of his teammate. Whereas the Australian’s tempo was robust, Norris’s benefit in sure observe sections, corresponding 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 because of its balanced aerodynamics, together with a brand new medium-load wing, and mechanical setup that absorbs observe irregularities nicely. In the meantime, after robust 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 challenge 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 automotive 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.
Purple 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, corresponding to elevating the experience peak within the case of Mercedes and Purple Bull.
The Brackley staff has proven within the final two GPs that they’re aiming for the bottom doable experience peak, to the extent that drivers regularly complained throughout follow concerning the automotive scraping the bottom. For Purple Bull, such points don’t go well with the traits of the RB20.
Purple 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, in the case of 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 better 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, 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 energetic in FP1, working excessive gasoline hundreds in a protracted stint, clearly making ready extra for the race than the dash.
