Ferrari laid down an early marker at the Qatar Grand Prix on Friday, heading the timing boards in FP1 with Charles Leclerc almost half a second clear of his rivals.
The Scuderia trail McLaren by 24 points in the constructors' championship, looking to become the first team since the 1980s to win the team competition without having a driver in the top two.
Red Bull are nominally still in the running too, but at 53 points behind and with Sergio Perez struggling to pull his weight, they're likely to officially drop out of contention this weekend. Perez could only set the 18th fastest time of the session, with Max Verstappen 11th.
The running in Lusail, the only practice session of the weekend thanks to the sprint format, featured a number of drivers finding the limits of their cars, often running well wide with Lando Norris in particular having a huge snap of oversteer.
