Phew. That's the first practice running of the 2026 season in the books and it's a Ferrari one-two to start us off.
Charles Leclerc is 0.469 seconds quicker than team-mate Lewis Hamilton at the top followed by the two Red Bulls of Max Verstappen and Isack Hadjar. Briton Arvid Lindblad, in his debut session in Formula 1, puts his Racing Bulls in fifth and Aussie Oscar Piastri is sixth after some earlier issues in his McLaren.
World champion Lando Norris, meanwhile, has been sat watching on while the team deals with some precautionary gearbox checks.
Brit Arvid Lindblad is the sole rookie on the grid this year compared to the five or six we had last season. The teenager has taken over from Isack Hadjar over at Racing Bulls for his debut in Formula 1 and at the end of this first practice session, Lindbald goes fifth fastest on the soft compound.
Oscar Piastri stays a nearly second off the pace in ninth after his flyer was comprised by that Sergio Perez spin. The Australian has kept the soft tyre, while the likes of Lewis Hamilton and Max Verstappen take the mediums for the final minutes of this opening practice session.
Off we pop again and Oscar Piastri is winding up for a push lap in his McLaren but Sergio Perez has spun off in his Cadillac after locking his rear tyres. "I'm having a lot of engine braking," says the Mexican driver.
The marshals are on the scene to give Alex Albon a helping hand with his stricken Williams.
Just before that stoppage for Albon, Ferrari's Lewis Hamilton picked up a lovely slipstream which propelled him to the top of the board with a 1:20.736 on the soft compound.

Williams are another team who have found the going tough before the season has even started. Alex Albon said on Thursday the car is a bit overweight at the moment and the team will probably be at the back of the midfield this year.
And now Albon has come to a stop on track. He calls into base to say he's "lost power steering and everything" around Turns 10 and 11.

Charles Leclerc versus Max Verstappen in a championship fight - discuss.
The Dutchman finds more pace in his Red Bull - 0.040 seconds to be exact - and climbs over the Ferrari of Leclerc to sit at the top of the timesheets once again.
His team-mate Isack Hadjar has just had a lock-up on his latest lap and ending up running wide off the track.

World champion Lando Norris is having to watch on from the McLaren hospitality suit, as his car is undergoing some work in the garage which the team say is "precautionary gearbox checks".
Charles Leclerc can harvest energy with the best of them and the Ferrari man goes straight to the top after his first push lap on the softs with a 1:20.829, ahead of the Red Bull pair Max Verstappen and Isack Hadjar.
George Russell has been tagged as the favourite to take the title this season, as many people feel Mercedes have hit the jackpot with their car and engine under the new regulations.
Russell has just headed out on the soft compound, so now we'll get to see the Briton push hard around Albert Park.
However, he can't knock down the likes of Ferrari and Red Bull, and after his first push on the softs, Russell goes fifth on the timesheets, eight tenths away from Charles Leclerc's best marker on the mediums.

Ferrari and Red Bull have started this session really impressively. They are running 1-2-3-4. It is a surprise, I have to say, because everybody in the pit-lane thought after pre-season testing that Mercedes were in the best place.

Isack Hadjar's first job at Red Bull will be to collect as many points as possible and share the load with four-time world champion Max Verstappen, who basically carried the team to their third-place finish last season.
The Frenchman has started positively in thid opening practice session and now he sits above Charles Leclerc with a 1:21.460, still on those yellow medium tyres.
Meanwhile, over at Cadillac: "I got fully blocked by Lewis," says Finn Valtteri Bottas.
