11:00

Ricciardo finishes on top with his all-time lap record 1:42.489, just ahead of Vettel and Verstappen

11:00

Chequered flag!

10:59

Grosjean has another moment, taking to the run-off at Turn 18

10:57

Replays show Grosjean running wide at Turn 2 and rejoining the track to the right of a new bollard at Turn 3

10:52

He reverses out and continues on his way

10:52

Replays show Hamilton locking up and running straight on at Turn 14

10:51

He’s been sliding around and locking up throughout the session

10:50

“The rear end is just undriveable – it’s moving around so much,” reports Bottas

10:48

But this is not a representative session – FP2 will take place under the lights, at a similar time to qualifying and the race

10:48

Ricciardo still leads the way with what is the fastest ever lap around the Marina Bay Street Circuit

10:45

Replays show him clattering the kerbs down at Turn 1

10:45

Perez goes fifth, slotting between the Silver Arrows

10:41

Stroll is talking to engineers as mechanics work on his car – it has been up on jacks after that early loss of power

10:39

Vettel goes P2 with a mid 1m42s lap on fresh Ultra Softs

10:37

“No! Please, no!” Alonso shouts in response…

10:37

“Would you like another attempt?” Alonso’s engineer asks

10:36

Red Bull 1-2, Mercedes 3-4 and Ferrari 5-6 as it stands…

10:35

Ricciardo now moves 0.121s clear with his latest lap

10:34

Verstappen improves again – he’s down to a 1:42.610

10:34

Alonso shoots up to sixth, just under a second off the pace

10:33

So the two big straights are giving Mercedes the upper hand in S1, with Red Bull quicker through the twisty S2 and S3 sections

10:29

He just managed to keep it out of the wall!

10:29

Replays show Giovinazzi sliding his way out of Turn 21

10:28

Verstappen, back out on a fresh set of Ultra Softs, returns to P1 with a 1:42.805

10:27

Palmer now squeezes into the top 10, ahead of Hulkenberg

10:26

Top 10 update: HAM, VER, BOT, RIC, RAI, VET, PER, VAN, HUL, MAS

10:26

“Oh my god, really?” Alonso comments, when asked to change settings

10:25

“I have no power,” is the message from Alonso…

10:21

“Now the tyres are gone,” reports Bottas

10:19

He’s half a second down on team-mate Hamilton as it stands

10:19

Replays show a big lock-up for Bottas at Turn 13

10:19

Both Vandoorne and Alonso are running Honda’s Spec 3.7 power unit here

10:17

So it’s a Mercedes on top, at least for the time being…

10:16

Hamilton, also on Ultra Softs, jumps clear with a 1:42.904

10:12

Bottas, now on Ultra Softs, goes second – between the Red Bulls

10:10

So perhaps that is in relation to the earlier radio message

10:10

Renault mechanics are working on one of Hulkenberg’s brake drums

10:08

Grosjean spins and continues at Turns 16/17

10:08

Replays show Verstappen drifting his way through Turns 12/3

10:07

Remember, older parts are often used during Friday practice

10:07

Stroll reports an engine issue and crawls back to the pits

10:05

Ericsson locks up at Turn 18 and backs out to avoid the wall

10:04

Ricciardo briefly leads, before Verstappen clocks a 1:43.278

10:00

Verstappen now goes fastest with a 1:44.058

09:59

He reports that “it’s OK” and continues on his way

09:59

Replays show a big lock-up for Palmer at Turn 13

09:59

A mixture of Ultra Softs and Super Softs in these early stages

09:59

Ricciardo goes second, splitting the Mercedes drivers

09:57

For reference, the best time posted in FP1 last year was a 1:45.823, with pole position a 1:42.584

09:56

Hamilton moves to the front with a 1:44.236

09:54

Despite that message, Hulkenberg goes second

09:53

Some early concerns down at Renault…

09:53

Hulkenberg is told to change a setting on his steering wheel, along with the clear message: “It’s urgent”

09:52

Gelael is making steady gains – he’s improving by around a second per lap and now 6.3s down on Bottas

09:49

Gelael posts his first time, some 10 seconds adrift of Bottas

09:46

Another lap, another improvement from Bottas – he’s down to a 1:46.334

09:44

He improves by a couple of seconds next time around

09:44

Bottas gets the first time on the board: 1:48.770 (Super Softs)

09:43

09:42

If you missed it, Bottas has signed a one-year extension with Mercedes

09:41

Bottas is also out on track, catching up a lock-up into Turn 14

09:41

Moments after we mention his name, Hamilton emerges

09:39

All drivers bar Hamilton have been out for installation laps

09:38

“I’m excited to be working with Robert and his return to F1,” Rosberg posted on social media. “He and Lewis [Hamilton] were the fastest I raced against.”

09:34

Vandoorne, Raikkonen and Ricciardo are running with the ‘halo’ on their install runs

09:34

Only a few damp patches remaining on the surface now

09:33

Vandoorne has been told that the track is “dry”

09:31

Vettel trails Hamilton by three points, after the Briton’s back-to-back wins at Spa and Monza

09:31

Vettel is the first driver out on track

09:31

Green light! FP1 is underway

09:28

At Toro Rosso, Formula 2 racer Sean Gelael will make the first of four planned FP1 runs this season, using Carlos Sainz Jr.’s car

09:28

Ferrari-backed Antonio Giovinazzi will get a run at Haas, in place of Kevin Magnussen, to make up for his cancelled outing in Italy

09:27

There will be two test/reserve drivers in action in FP1

09:25

09:22

Back to the track – Pirelli’s Ultra Soft, Super Soft and Soft tyres have been supplied for this weekend’s event

09:20

We should finally get some engine confirmations a little later today…

09:19

We’ve already had one announcement today, but not related to that set of dominoes – instead, Singapore has signed a new deal to host F1 through 2021

09:18

Of course, the past fortnight or so has been dominated by F1’s ongoing engine saga, involving McLaren, Honda, Renault, Red Bull and Toro Rosso

09:18

As usual, FP1 will take place in daylight, before the sun sets and the floodlights come on for FP2

09:16

It’s been wet and windy at Marina Bay, but conditions are improving…

09:15
