McLaren drivers Lewis Hamilton and Jenson Button have both lauded the new United States Grand Prix track ahead of next weekend's race.
The English duo have driven the circuit on the McLaren simulator and are looking forward to a return to the US on the Formula 1 calendar for the first time in five years.
Button tweeted: "Good couple of days at the [McLaren Training Centre], yesterday driving the simulator for Sao Paolo and Austin and I must say Austin is Epic!!"
Hamilton, who won the last US GP in Indianapolis in 2007, added: "I have to admit, I'm absolutely made-up that we're going back to the States.
"It's a fantastic country and a place where our sport truly deserves to be. I think the Circuit of the Americas looks like it could also be the place that modern Formula 1 finally calls home."
The Circuit of the Americas has been designed to incorporate elements from tracks across the world into one fluid lap.
