Round 21 of the 2023 FIA Formula 1 World Championship takes the Formula 1 discipline to Brazil, for the Sao Paulo Grand Prix, at the Autodromo Jose Carlos Pace.
Following just some days after the incident-filled Mexico City Grand Prix, Formula One made a nine-hour flight to Sao Paulo that performs host to the ultimate vacation spot of the season’s final triple header. The Brazilian Grand Prix, that has been known as Sao Paulo Grand Prix since 2021, has been held in Interlagos since 1990, but it surely has additionally taken place at the Jacarepaguà circuit in Rio de Janeiro 10 instances.
Sao Paulo will host the sixth and ultimate F1 Sprint occasion of the season, marking the third successive yr during which Interlagos has held the various format.
As far as the tyre choice is worried, groups must work with a trio of barely more durable compounds at Sao Paulo as Pirelli selected the C2 compound as P Zero White arduous, C3 as P Zero Yellow medium, and C4 as P Zero Red tender.
Tyre degradation has not adopted the similar sample lately. While chilly climate often results in decrease degradation, it may be fairly extreme in excessive ambient temperatures. The undulating circuit is compact, at solely 4.3km, and contains a sequence of long-radius medium- and high-speed corners, which means that tyres are subjected to huge stress. Strong straight-line velocity can also be very important attributable to the prolonged full throttle part into the Senna S, a fancy via which drivers plunge, which is known as after the Brazilian legend Ayrton Senna.
As a results of this extraordinarily lengthy full-throttle, curved part the place tyre can get well from the stress generated by the long-radius corners of the center sector, the general tyre stress is medium based on Pirelli with each the lateral and longitudinal forces are thought of common. That is why climate situations play an unlimited position in tyre behaviour, as larger temperatures considerably improve the tyre degradation and put on, greater than at many different venues.
The minimal beginning pressures can be set at 23.0 psi for the entrance tyres and 21.0psi for the tyre tyres. Teams can be restricted to camber limits of -3.25° for the entrance and -2.00° for the rear tyres.
As for the technique in final yr’s Brazilian F1 race, each race winner George Russell and second-placed Lewis Hamilton adopted an equivalent two-stop technique: tender tyres at the begin, adopted by a center stint on medium and a ultimate stint on tender. Ferrari driver Carlos Sainz accomplished the podium with a three-stopper, alternating between the medium and tender compounds.
Commenting on the forthcoming Sao Paulo Grand Prix, Pirelli’s Motorsport Director Mario Isola stated: “The Interlagos circuit in the Brazilian metropolis of São Paulo is well-known for offering thrilling races. The lap is barely 4.309 kilometres lengthy, making it considered one of the shortest of the yr, with solely Monaco and Mexico City being shorter.
“It’s additionally run anti-clockwise and located on a hillside, which supplies it a novel character. The drivers face a steep downhill part after the first nook, adopted by an extended climb uphill with a number of winding turns, after which an extended straight main again to the end line. The monitor has 15 corners – 5 right-handers and 9 left-handers – with a number of route modifications. Interlagos has a little bit of all the pieces, that includes low in addition to medium velocity corners, and the vehicles operating fairly a excessive stage of downforce. The forces appearing on the tyres are moderately balanced between lateral and longitudinal.
“The asphalt itself has a excessive stage of roughness: typical of everlasting tracks with an extended historical past behind them. Degradation is especially thermal, so the C2, C3, and C4 compounds have been chosen. A two-stopper is the most probably technique, whereas a one-stopper would require loads of tyre administration; affecting race tempo.
“The safety car has often featured during the grand prix, introducing another key variable, and we have also seen that weather conditions can vary rapidly and widely at this time of year as well. Interlagos will additionally host the final sprint round of the season, giving the teams and drivers another chance to assess tyre behaviour over long runs. Since sprint races came in for the 2021 season, Interlagos has always been one of them – a sure sign of how this track consistently delivers the sort of close racing that suits the sprint format,” Isola concluded.
