Fascinating fact: Bruce McLaren, Jochen Rindt and Emerson Fittipaldi are among a number of well-known drivers to have claimed their breakthrough F1 wins in United States Grands Prix. Of the current grid, though eight different drivers have led at least one lap, only Lewis Hamilton (2007 and 2012) and Sebastian Vettel (2013) have triumphed on US soil.
Potential record breakers: After dominating in Russia, Mercedes have now scored nine one-two finishes this year. They need just one more over the remaining three races to tie McLaren's record from 1988, and two more to eclipse it.
Turbo history: If a Ferrari-powered car wins the race it will be the first Ferrari turbo win since the 1988 Italian Grand Prix.
