"Race day in Austin was quite a rollercoaster of emotions," said Toto.
"While we didn't quite have the pace to win, it was great to be in the mix at the front and leading the race.
"The upgrades we brought to Texas delivered a step forward and we were closer to the front than we have been recently.
"Lewis drove an outstanding race to finish P2 and George scored a good haul of points despite his damaged car.
"We need to keep this momentum going. We're cautiously optimistic heading to Mexico but the W13 can be unpredictable from track to track, so we'll have to wait and see.
"It's always good to be back in Mexico. The fans are fantastic and the atmosphere is spectacular every time we visit. They know how to put on a brilliant show so we're looking forward to being back in Mexico City.
"Nyck will be replacing George in FP1 this weekend as part of the young driver session allocation. We're excited to see him back in W13 and seeing how he performs."
