Marko locates the problem: "Correlation not optimal for three races".

Helmut Marko thanked Red Bull's engineers on the circuit and all the employees of the Austrian racing team who helped improve the RB16B in Milton Keynes. The first day at the Texas circuit didn't go according to plan, but the Austrian team improved on Saturday. 

"We are really proud of our technicians for optimising it so well," Marko is quoted as saying by Sky's German branch. The 78-year-old Austrian continues."We have not been optimal in the correlation for three races now."

Red Bull always had confidence

Changes to the set-up that work out well on the simulator are very disappointing on the track itself. Yet the bottom line seems to be in place now. "Our car is definitely harder to tune than maybe the Mercedes. They come here and they are immediately fast. We [knew] about our potential, we just had to unlock it."

They also looked very closely at which parts of the track Max Verstappen and Sergio Perez needed to push on and where they might need to hold back a little. "For example, Max was maybe a bit too aggressive yesterday, he had already overheated the tyres so much in sector one that there was nothing left in sector three."
