After the controversial race in Qatar where drivers struggled in the heat, F1 is back in action for this weekend's United States Grand Prix where they could once again be facing testing conditions.
But the heat is on regarding more fronts as another sprint weekend means the event in COTA is restricted to just one practice session ahead of Friday's qualifying later in the day.
That makes it a crucial one hour session for the teams to make sure they have ticked all the right boxes ahead of qualifying and Sunday's race, as well as get a headstart into Saturday's sprint sessions.
Either way, Red Bull are as ever favourites heading into the US Grand Prix, having triumphed easily at the Losail Circuit last time out with three-time world champion Max Verstappen.
Here is all you need to know heading into the opening session in Austin.
