Q: Maurizio, what did you make of the performance in Austin compared to the last race in Suzuka?

Maurizio Arrivabene: This is a high-downforce track and not comparable to Suzuka. In Suzuka we made some steps, but we knew that coming here it would not be so easy. But in reality Sunday was not so bad compared to Friday or Saturday. Unfortunately we couldn't get the most of our race.

Q: Was Raikkonen's pit stop a failure in the system or a human error?

MA: We had a problem with a nut – and that was it basically for Kimi.

Q: Kimi was given the green light to go although the wheel was not properly attached. Do you need to review the system you have in place?

MA: It has nothing to do with the system. It was simply unfortunate. That is all.

Q: Coming back to the overall car performance. This track is not the only high-downforce track. In Singapore you were pretty competitive - so why not here? What's the difference?

MA: Well, obviously we knew that this track is not really preferable for us. We knew that. But you have to look at the overall situation: if you want to solve problems this year you are losing time for next year.
