The specific calls for of the Autodromo Hermanos Rodriguez urged teams to make key tweaks to their vehicles for this weekend. F1Technical’s senior author Balázs Szabó analyses the upgrades debuted in Mexico City.
With the Autodromo Hermanos Rodriguez situated at greater than 2,200 metres above sea degree, engineers have to take care of distinctive necessities which might be vastly completely different to something skilled at different circuits. The excessive altitude means skinny air, poorer than regular warmth dissipation from parts resembling energy items (that are already working tougher in the low density air) and brakes.
It is subsequently no shock to see many teams debut track-specific modifications to their vehicles.
Red Bull
The reigning world champion teams have enlarged the ahead exit louvres for the appropriate aspect. The group famous that the tweak to the cooling configuration of the RB19 have been carried out in toder to “achieve sufficient cooling in the lower atmospheric pressure of Mexico City.”
AlphaTauri
AlphaTauri had been among the many teams which have introduced vital upgrades to Austin. The outfit from Faenza have debuted circuit-specific entrance brake ducts and a bigger engine cowl exit in Mexico City.
The group famous that the brake ducts and the central engine cowl exit have “been increased in size to increase mass flow through central radiator cores given the extreme cooling demands of this high altitude circuit.”
Williams
Williams have introduced a bigger engine cowl with a much bigger rear centreline exit, however it is going to solely be used if the engineers suppose that it’s required. This modified engine cowl permits extra cooling air to be drawn via the coolers to cut back the temperature of the PU and gearbox fluids.
Furthermore, Williams have designed panels with extra louvres which might be obtainable if required.
Ferrari
After securing a pole place and struggling for race tempo in Austin, Ferrari have additionally arrieved in Mexico City with a number of tweaks to the cooling structure of their SF23.
The Scuderia have employed extra cockpit louvres and cooling exit gurneys on their automotive with the group claiming that “these new louvres and gurney geometries are extending the top end of the engine cooling capacity.”

Alpine
Alpine have impleted modified each to the cooling louvres and the engine cowl of their A523 in Mexico City. Their 2023 F1 challenger has received deeper mid louvres than the earlier most cooling louvres seen on the automotive. This replace was used in Qatar FP1 as a check merchandise for this race.
Moreover, the A523 sports activities a Mexico-specific engine cowl on which the panel exit on the rear of the automotive supplies larger cooling ranges.
McLaren
After their impessive efficiency in Austin, McLaren have arrived with decrease expectation in Mexico City. However, issues point out that their MCL60 have maintained its current efficiency degree.
In Mexico, the automotive contains a revised engine cowl geometry which “allows for increased massflow through the radiators, which is required at this circuit due to the particular ambient conditions.”
Moreover, McLaren have provide you with a bigger Front Brake Scoop for the Mexico City Grand Prix that has been designed to enhance entrance brake cooling capability.
Alfa Romeo
Alfa Romeo have redesigned the rear brake duct for the Autodromo Hermanos Rodriguez, albeit this transformation is just not a circuit-specific tweak, however for chasing for extra efficiency.
The up to date rear brake duct works in conjunction with the ground launched in Austin to enhance the aerodynamic effectivity of the automotive and generate downforce.
Haas
After debuting their extreme improve bundle in Austin, Haas have introduced cooling-related modifications to the louvres and engine covers.
There is a small modification on the exit of the Front Brake Duct Scoop which ought to enable “the engineers to adjust the brake cooling with a variation of the aerodynamic forces around the front corner.”
There are not any modifications at Mercedes or Aston Martin.
