Interlagos is usually synonymous with unpredictability, notably due to the uncertainty surrounding the Brazilian climate, with rain probably taking part in a job once more this weekend in response to latest forecasts. Nevertheless, when it comes to efficiency, the São Paulo circuit has to this point met the pre-race expectations, with McLaren establishing itself as the favourite by securing all the entrance row in dash qualifying.
Though Andrea Stella had steered that Interlagos is perhaps an unknown variable on this closing a part of the season, figuring out different tracks as doubtlessly higher suited to focus on the MCL38’s strengths, Ferrari anticipated that sure facets 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 automotive 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 purpose McLaren triumphed in Friday’s brief qualifying session; as in different rounds this season, McLaren’s robust 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 automotive’s potential 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 potential earlier than getting ready for the subsequent braking zone. Nevertheless, a lot of the deceleration part occurs in what is named a “mixed” method, the place the driving force is on the brake pedal whereas the automotive 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 components mirror tendencies noticed all through the season, like Ferrari’s normal 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 strategy in comparison with McLaren drivers: Charles Leclerc can anticipate throttle reapplication with out absolutely lifting off, gaining a 7 km/h prime velocity benefit in Flip 6.
Then again, Charles Leclerc can not absolutely 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 brief stretch main into Flip 8 braking.
The primary chicane additionally exhibits a McLaren benefit. Throughout observe, Ferrari tried to tweak its strategy 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 attaining larger speeds on entry and thru the nook but additionally by offering each drivers with robust 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 closing moments, squandering potential that might have positioned him forward of his teammate. Whereas the Australian’s tempo was robust, Norris’s benefit in sure monitor sections, akin 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 monitor irregularities properly. In the meantime, after robust ends in 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, notably with the dash in thoughts. Temperatures different considerably on Friday, with monitor temperatures dropping from over 50°C throughout FP1 to only over 30°C by qualifying as clouds rolled in. With such massive fluctuations, it turns into tough for groups to pinpoint the perfect window, some extent 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: Battling 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 monitor has all the time been difficult on this respect, however the work finished for this season appears to have worsened the issue. This caught groups off guard, forcing changes to setups, akin to elevating the experience peak 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 peak, to the extent that drivers continuously complained throughout observe 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 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.
Nevertheless, relating to working the entrance finish and pushing the entrance tires, Purple Bull’s recurring stability 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 endure 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 lively in FP1, working excessive gas masses in an extended stint, clearly getting ready extra for the race than the dash.
