After a lengthy winter break, F1 pre-season testing is here with three days of running at the Bahrain International Circuit.
The grid for the 2025 F1 season has been transformed after Lewis Hamilton's seismic switch to Ferrari.
Eight of the 10 teams have new driver line ups for this season, with many expecting it to be the tightest season in F1 history, given the rules have remained stable over the winter.
Teams now have eight hours of on-track action available to them per day across the next three days as they prepare for the start of the 2025 F1 season, which kicks off in Australia on March 16.

Several drivers have swapped around for the afternoon session.
McLaren: Norris
Ferrari: Leclerc
Red Bull: Verstappen
Mercedes: Russell
Aston Martin: Stroll
Alpine: Gasly
Haas: Ocon
Racing Bulls: Hadjar
Williams: Sainz
Sauber: Bortoleto
Green light at the end of the pit lane and the afternoon session is underway in Bahrain.
Another four hours of running to come at Sakhir!
18-year-old Antonelli impressed on his first morning of F1 pre-season testing for Mercedes.
Not only did the Italian set the fastest time, he also clocked the most laps of any driver on the opening morning of running with 78.
Antonelli has of course replaced Hamilton following the seven-time world champion's switch to Ferrari.
All of the teams will now have a 60-minute lunch break before the afternoon session. Verstappen, Leclerc, Norris and Russell will all be on track from 12pm UK time.
This morning, though, Antonelli set the pace for Mercedes, a tenth ahead of Lawson.

And Antonelli runs wide after locking up... no damage done though.
Antonelli is on top at the moment as we enter the final minutes of the morning session.
All cars are out on track except Lawson, Bearman and Hulkenberg. No notable sector times are coming up on the timing screens at the moment.
Drivers are running on heavier fuel, on worn rubber.
He's not the first driver to run wide today.

Not a lot of changes to the pecking order at the moment, with teams focusing on longer runs.
There's just under 25 minutes of the morning session to go.

He moves into second in the RB21, responding from his spin earlier in the session.
He's just over a tenth off Antonelli's pace.
Antonelli takes to the top now for Mercedes, lowering the benchmark to a 1m31.428s. He's 0.145s ahead of Albon.
Moments ago, Lawson had a big spin on the exit of the opening sequence of corners.

He slides into Turn 4 in the RB21.
A good sign for Alonso fans? The Spaniard looks like he's happy in the Aston Martin garage.
In terms of lap times, he's fifth overall at the moment, 0.3s off the pace.
Work is being done to Hamilton's Ferrari with just over 75 minutes left of the morning session.

There's just 0.9s between the top nine - Albon in first and Piastri in ninth. Bearman is cut adrift at the bottom of the timesheets, 4.0s off the pace.
Yet another oversteer moment for Hamilton, who runs slightly wide in the Ferrari.
