McLaren bring most upgrades for Mexican GP as fight for P4 continues

McLaren have made a number of changes to their car for the Mexican Grand Prix as they look to beat Alpine to P4 in the Constructors’ standings.

The Woking-based team have brought the most upgrades to the Autodromo Hermanos Rodriguez with a total of four changes made to the MCL36.

AlphaTauri have also been busy and made three changes, while three teams are running the same car that featured last time out in Austin.

Here are all the F1 upgrades ahead of the Mexican Grand Prix:

Mercedes

The Mexican Grand Prix will be the first time in 164 races Mercedes take to the track not as reigning Constructors’ champions and with that in mind, it seems they are looking forward to 2023.

With Nyck de Vries in the car, Mercedes will run a revised floor edge for FP1 to evaluate a different concept in this area of the car.

Red Bull

A lot of the talk surrounding Red Bull this weekend will be focused on off-track matters but on track, they have made one change to their car in the form of the coke/engine cover.

They have introduced an enlarged topbody central spin for more cooling, which they say should improve reliability.

Ferrari

No changes.

McLaren

Two of McLaren’s four upgrades focus on the coke/engine cover and three of their updates are circuit-specific.

Slots in the engine cover have been made to lower fluid temperatures, while an optional gurney on the coke exit will produce a similar result.

A new louvre has been designed to increase cooling massflow and additional winglets have been fitted to the rear brake duct assembly to increase local suction.

Alpine

No changes.

AlphaTauri

All three of AlphaTauri’s changes are circuit-specific and all focused on cooling.

The exit area of the front brake duct scoop has been enlarged to provide more cooling, while the size of the main rearward facing cooling exit at the back of the engine cover has also grown.

To increase air flow through the radiators, AlphaTauri have reduced the number of cooling louvres and spread them further apart.

Aston Martin

Just the one change for Aston Martin in the form of a new profile for the lower edge of the rear deflector.

Williams

Williams have also made a solitary change with an option to add additional exit area to the rear part of the louvre panel. The team say this will increase air flow but decrease the aerodynamic performance of the car, so will only be used when required.

Alfa Romeo

Alfa’s change comes on the floor body with a reconfigured geometry and modified side cutouts. The team say this will provide additional downforce and improve the car’s stability.

Haas

No change.
