Nico Rosberg knows the unpredictability of the weather conditions at the Circuit of the Americas could mean the work done on set-up on Friday meaning very little when it comes to Saturday’s running.

The Mercedes AMG Petronas Formula One Team racer finished second fastest to team-mate Lewis Hamilton in the opening session on Friday before topping the second session ahead of Daniel Ricciardo, with the temperature change in between sessions and the direction of the wind affecting performance.

Rosberg heads into the United States Grand Prix with a thirty-three point advantage over Hamilton in the championship, and will be looking for his ninth pole position of the season on Saturday.

“The running of the car was different between P1 and P2 because of the temperature; it was very cold when we ran this morning,” said Rosberg. “The weather also had a bearing on the balance of the car as it altered as a consequence of the changing wind direction around the track.

“It should be different tomorrow because the weather is going to change again, as it does frequently here in Austin, and it means what we learn today might not necessarily help us for Saturday.”
