Charles Leclerc set the pace in opening practice for the Abu Dhabi Grand Prix but the Ferrari man will be hit by a grid penalty in a major blow to their constructors’ championship hopes.
The 27-year-old finished 0.221 seconds clear of Lando Norris at the Yas Marina Circuit, on a weekend where Ferrari and McLaren will battle to win the championship.
McLaren hold a 21-point lead heading into the weekend, with the Scuderia likely to need a one-two finish to stand a chance of winning their first crown since 2007.
Leclerc did not take to the track at the start of Friday’s opening running, missing almost half of the session before posting the fastest time.
Ferrari confirmed that they had to change the battery pack on his car, meaning Leclerc will take a 10-place grid penalty on Sunday.
The Monegasque is also battling to finish second in the drivers’ championship, coming into the weekend eight points adrift of McLaren’s Norris.
Ferrari lined up with Leclerc’s brother Arthur standing in for Carlos Sainz, making them the first brothers in F1 history to take part in a session for the same team.
The session featured a host of rookie drivers as world champion Max Verstappen handed his Red Bull car over to Isack Hadjar.
Lewis Hamilton, on his final race weekend for Mercedes, finished third fastest ahead of team-mate George Russell.
