Alpine will bring their final updates of the season to Austin as they continue their battle with McLaren in the Formula 1 Constructors Championship.
After introducing a new floor for the A522 at the Singapore Grand Prix, the team will make a "small modification" according to Team Principal Otmar Szafnauer to the outer section of the latest floor.
"We brought a new floor to the car for Singapore and Japan and that worked as expected," said Szafnauer.
"We especially saw the improvements at Suzuka, which is a more conventional circuit than Marina Bay, and we were satisfied with how it performed and that bodes well for futures races.
"For Austin, we are bringing a small modification to the outer section of the latest floor, which is our final update of the year."

Austin will be a 'demanding track'
Szafnauer expects the bumpy and high speed Circuit of the Americas to be a "demanding track" for the drivers, as they look to extend their 13-point lead on McLaren.
He added: "It’s always great when we race in the United States – home turf for me – especially in Austin, which is a favourite among many of us in Formula 1.
"It’s a very demanding racetrack that usually brings some good racing with a fast first sector, the long, back straight and some slow-speed corners towards the end, which has some opportunities for overtaking."
