F1's trip to Mexico always presents teams with unusual challenges, due to the twisty nature of the circuit and the high altitude.
Rain is forecast for the weekend too and it's not a track that's typically suited our car, so we're expecting another close and hard-fought race.
"Our next stop brings us to Mexico City where we will face a very different challenge," Toto explained.
"The Autódromo Hermanos Rodríguez is an outlier given its high altitude and the demands this puts on the cars and power units.
"It has been one of the weaker tracks for us in previous years and we expect a hard fight with Ferrari and Red Bull.
"The weather forecast predicts conditions similar to those we had in Austin which might throw everyone another curveball by limiting dry running.
"We know that it is not going to be an easy race, but everyone in the team is focused, motivated and determined to keep the pressure on until the chequered flag in Abu Dhabi."
