"I'm optimistic that the track will suit the high-speed characteristics of our car, which showed improved pace in both India and Abu Dhabi," he said. "After a couple of difficult races, it'd be great to get a strong finish for all the Formula 1 fans in the US.

"I had one of my most enjoyable races of the season at the Circuit of the Americas last year - I'd struggled in qualifying, starting twelfth, but just got my head down on Sunday afternoon, had a great fight, and eventually finished fifth, which was extremely satisfying.

"The first sector of this circuit ranks as one of the best parts of a racetrack anywhere in the world. The first corner is really tricky, because it's steep and blind, after that, the circuit just winds through an incredibly fast switchback until the heavy braking for the back straight.

"After such an intense start to the lap, the straight offers a bit of a breather until you commit once again to the final sector, which is a series of slow-speed, quite technical corners. Again, there's a real variety of corner here, and it's fun to nail the sequence. It's definitely a place where accumulated knowledge of the layout can add to your speed."
