Tactic guidebook for the Sao Paulo Grand Prix
Yesterday’s 24-lap Sao Paulo F1 Dash indicated that tyre degradation will be a significant element in present-day F1 race at the Autodromo Jose Carlos Rate. F1Technical’s senior author Balázs Szabó requires a search at what is achievable right now about race techniques.
As considerably as the tyre range is anxious, groups have a trio of a little bit tougher compounds at Sao Paulo in contrast to the variety that was obtainable in Mexico Metropolis just a handful of times back as Pirelli selected the C2 compound as P Zero White challenging, C3 as P Zero Yellow medium, and C4 as P Zero Pink smooth.
The undulating Jose Carlos Rate circuit – or Interlagos as we have a tendency to get in touch with it – is compact, at only four.3km, and characteristics a sequence of extensive-radius medium- and superior-pace corners, which means that tyres are subjected to massive tension. Solid straight-line pace is also critical thanks to the prolonged entire-throttle segment into the Senna S, a sophisticated by way of which motorists plunge, which is named right after the Brazilian legend Ayrton Senna.
As a final result of this very extensive entire-throttle, curved segment wherever tyres can get better from the tension created by the extensive-radius corners of the center sector, the total tyre tension is medium in accordance to Pirelli with the two the lateral and longitudinal forces thought of normal. That is why temperature ailments engage in an massive function in tyre conduct, as greater temperatures substantially improve tyre degradation and have on, additional than at numerous other venues.
The minimum amount starting up pressures have been established at 23. psi for the entrance tyres and 21. psi for the tyre tyres. Groups have been restricted to camber limitations of -three.25° for the entrance and -two.00° for the rear tyres.
What does the details propose
Adhering to yesterday’s Dash race, groups and motorists have some critical details to establish on which can assist them to determine the tactic selections that are the finest suited for the starting up place, set up, downforce ranges, and degradation of their autos.
Climate typically performs a critical function in the way autos and tyres function, and it is even additional the scenario in Sao Paulo wherever a slight improve or fall of temperatures can guide to considerable improvements and can even have an impression on the pecking get.
Adhering to Friday’s qualifying when hefty winds and torrential rain induced the session to be lower brief, yesterday’s Dash Shootout and the Dash Race took location in heat ailments, major to substantial degradation. Even though there is only a slight probability of rain for Sunday, the forecast for the Sao Paulo Grand Prix is for a lot cooler temperature.
It can assist groups that have experienced concerns with tyre administration yesterday, significantly Haas and Mercedes. The American staff elected to get started the dash race on the additional strong medium compound as they have been battling with very superior tyre have on all throughout the year, but even so the two Kevin Magnussen and Nico Hulkenberg ran out of tyre in the closing phases of the 24-lap Dash.
Mercedes who have been great in tyre administration in 2023 endured a really challenging 100km sprint yesterday as the two Lewis Hamilton and George Russell encountered superior tyre have on with the 7-time earth winner struggling from excessive degradation on the rear tyres.
A different element that can impact techniques is achievable race interruptions. Even though a pit prevent less than ordinary eco-friendly flag ailments requires all over 21 seconds, it is diminished to just twelve seconds through protection motor vehicle or digital protection motor vehicle durations. Primarily based on modern races in Sao Paulo, the probability for a protection motor vehicle interruption is established at 70 for each cent even though the probability for a digital protection motor vehicle time period is established at forty for each cent.

And coming to the most critical issue: Pirelli – unsurprisingly – expects that the two-prevent tactic will be the speediest strategy to present-day seventy one-lap Sao Paulo Grand Prix.
The speediest tactic could be to get started on the smooth compound and entire a seventeen-22-lap stint in advance of switching to the mediums. The final prevent would see motorists pit for softs once again and entire a ultimate stint of somewhere around twenty laps on the C4 compound. This tactic could be significantly superior for motorists who have at minimum two new sets of softs obtainable – Daniel Ricciardo, Valtteri Bottas, Logan Sargeant and Zhou Guanyu.
A different achievable two-prevent tactic would see motorists accomplish two opening stints on the yellow-walled medium tyres with the 2nd stint a little bit for a longer period than the opening one particular in advance of finishing the race length on the smooth compound.
This tactic seems to be the most practical for motorists who have a new established of smooth and two new sets of mediums – Max Verstappen, Charles Leclerc, Carlos Sainz, Lance Stroll, Fernando Alonso, Nico Hulkenberg, Esteban Ocon, Pierre Gasly, Kevin Magnussen, Alexander Albon.
Primarily based on the details collected this weekend, a a few-prevent tactic is also practical. It would contain a few stints on the softs and one particular on the medium – this could be achievable in diverse permutations. Final 12 months observed the Ferrari duo of Carlos Sainz and Charles Leclerc entire the Sao Paulo Grand Prix with a a few-prevent and taking into consideration that they concluded the race in P3 and P4 respectively, it would be not stunning if an individual chases a a few-prevent strategy.
A one particular-prevent tactic is also achievable with an opening stint on the medium and a 2nd stint on the challenging. Nevertheless, it would contain a superior diploma of tyre administration or a protection motor vehicle time period that would occur in at the correct minute for the motorists who endeavor a one particular-prevent tactic.
