Toro Rosso has confirmed Brendon Hartley, who won this year's Le Mans 24 Hours, will drive for the team at the U.S. Grand Prix while Pierre Gasly contests the championship finale of Super Formula in Japan.
New Zealander Hartley was formerly a Red Bull junior and had previous testing experience with the team in 2009, but his recent career has almost exclusively involved World Endurance Championship (WEC), a title he won alongside Mark Webber in 2015. He will make his debut alongside the returning Daniil Kvyat, who had been stood-down by the team at the last two races.
