Toto Wolff, Head of Mercedes-Benz Motorsport: “This race in Austin is becoming real Lewis Hamilton country: three wins in a row, and four in total, after a perfect and really controlled drive today. We have had some pretty dramatic races in recent weeks, including what happened in Malaysia of course, so it was good to have a drama-free afternoon today and see Lewis put in such a strong drive. As for Nico, he's in a tricky situation right now because he knows he cannot afford to have a DNF. Probably that was part of why he lost position in Turn One, but then he was looking good to get back to P2 with an offset tyre strategy before the VSC meant we could pit and gain the position that way. It was also great to see our pace today: Things looked much closer with Red Bull in practice but our engineering team did some good work on Friday night and we had a nice advantage in qualifying and the race.
