Red Bull have introduced an updated cooling louvre to their RB19 ahead of the 2023 Mexico City Grand Prix, as the team aims to solve a reliability concern by combatting the high-altitude of the track.
The Autodromo Hermanos Rodriguez is situated 2238m above sea-level meaning that the air is much thinner at that altitude. Whilst the benefit is a reduction of drag due to less air resistance, increasing straight-line speed, it does comes with a penalty elsewhere.
The trade-off is that there isn’t as much air to keep the cars cooler and with Formula 1 cars notoriously prone to overheating there can be issues with the power unit or brakes, issues capable of leading to retirement from the 71-lap race.
The world champions bid to solve the conundrum by enlarging the forward exit louvres on the right side of their car, with the goal of achieving their desired level of cooling in the lower atmospheric pressure of the Mexican capital.
Red Bull, as part of modern F1 regulations, are mandated to publicly state updates and upgrades brought to any race weekend and this track-specific change is the only one they have brought.
The requirement is part of an open-knowledge initiative aiming to help the slower teams find ideas to close up the field spread and thus create closer and more competitive racing.
When is the 2023 Mexico City GP?
The 2023 Mexico City GP will begin at 2pm local time in the capital of the North American country on Sunday, October 29. For British audiences that will be a nice evening start of 8pm, while fans in the USA can watch the race at 4pm ET and 1pm PT.
Max Verstappen won the previous two races in 2021 and 2022 and he could be challenged this year by Lewis Hamilton, who won the event in 2019.
Sergio Perez, in front of his adoring home fans, will look to finish on the podium once again after finishing third in the last two editions of the race.
