Thanks very much for joining us on day one of testing here in Barcelona. We'll be back tomorrow with all the action from day two from 7:45 AM. Make sure to set your alarms!
 
As promised, here's our testing day one wrap, as Lewis Hamilton leads Mercedes' charge and Racing Point show well with its copy of last year's Merc W10.
Barcelona F1 testing: Hamilton fastest, Mercedes dominates day one
So Lewis Hamilton topped the times on day one of testing - which appears to give credence to James Allison's explanation last week that Mercedes wouldn't be pulling a repeat of its 2019 hoodwink on the field by revealing an all-new car in week two. We'll have today's testing wrap coming shortly, along with news and reaction from the paddock.
Cheer up Toto, has anybody told you Mercedes are 1-2?

The sun sets on day one of testing. We think the photographers have earned their money today.

The whole field bar Giovinazzi - who didn't appear to do any single-lap runs - is covered by 1.5 seconds.
Chequered flag. The opening day of F1 testing for 2020 ends in a Mercedes 1-2, led by Lewis Hamilton.
Haas in Magnussen's hands has now also surpassed the 100-lap mark, so that makes it 10 teams out of 10. Looks like they'll all cope just fine with the reduction in testing.
The current laps are all much-of-a-muchness, flitting between the 1m21s and 1m22s. Hamilton's in the 1m18s on quite a consistent basis, which seems like a lower-fuel race-run time.
Leclerc comes in for some used C2s, as we drift towards the dying stages of the session. The left-front was a bit sparky when the wheelgun was applied which, if nothing else, looked cool.
Latifi and Giovinazzi join Kvyat and Leclerc on-track for the final 15 minutes. There's not a whole bundle of things happening out there...
Haas is the only team yet to surpass the 100 lap mark - which is ever so slightly annoying.
If you're after the full breakdown of laps completed...

Verstappen 161
Sainz 152
Leclerc 118
Kvyat 103
Magnussen 99
Hamilton 85
Bottas 79
Russell 73
Giovinazzi 66
Ocon 62
Latifi 60
Kubica 59
Perez 58
Stroll 47
Ricciardo 46
Ricciardo has managed the fewest laps of those to have taken to the track so far, which is a shame because his new purple lid is a sight to behold. We approve.

Mercedes has now surpassed Verstappen's 161 laps - the cumulative count of Hamilton and Bottas stands at 162. That seems ominous...
Here's one final timing rundown before the end of the session:

1 Hamilton 1m16.976s
2 Bottas +0.337s
3 Perez +0.399s
4 Verstappen +0.540s
5 Kvyat +0.722s
6 Sainz +0.866s
7 Ricciardo +0.897s
8 Ocon +1.028s
9 Russell +1.192s
10 Stroll +1.306s
11 Leclerc +1.313s
12 Latifi +1.406s
13 Kubica +1.410s
14 Magnussen +1.490s
15 Giovinazzi +3.120s
Leclerc's on the practice starts, it seems - he's not been time-chasing today, currently sitting in P11 overall.
One thing we've seen today so far is seemingly bulletproof reliability. There were a few breakages in testing last year, but we've not experienced that today.
There's 30 minutes remaining.
Ricciardo goes a smidgen faster on that one, logging a lap in the 1m17s on a set of C2s.
Hamilton's continuing to flex his muscles out there, going a good chunk faster in sectors one and two - before slowing it down for the final sector.
There's a bit more on-track activity in this final 40 minutes - six cars currently lap the field.
Latifi's gone out with some probes sellotaped to the rear of his car, checking out how the diffuser is performing. The first clause in that sentence sounded a tiny bit rude...
 
Of the current grid, Giovinazzi's surname has by far the biggest Scrabble score at 32, some margin ahead of Raikkonen and Verstappen - both on 17. These are the facts you needed to know.
Just Verstappen and Giovinazzi are circulating on-track at the moment. Verstappen hits 158 laps, while Giovinazzi has done 100 fewer - although Kubica drove the Alfa this morning.
Total laps so far:
Red Bull - 157 laps
Mercedes - 151
McLaren - 142
Williams - 128
Alfa Romeo - 115
Ferrari - 114
Renault - 98
Racing Point - 95
Haas - 92
AlphaTauri - 90
Here is the order rundown with just under an hour of day one to go:
1 Hamilton 1m16.976s
2 Bottas +0.337s
3 Perez +0.399s
4 Verstappen +0.540s
5 Kvyat +0.722s
6 Sainz +1.025s
7 Ocon +1.028s
8 Ricciardo +1.120s
9 Russell +1.192s
10 Stroll +1.309s
11 Leclerc +1.313s
12 Latifi +1.406s
13 Kubica +1.410s
14 Magnussen +1.490s
15 Giovinazzi +3.120s
Sainz has bolted on the C3 tyres - well, his mechanics have. His first lap on them was just 0.02s off his best today - and he now comes up to complete his 142nd lap.
Stroll brings his running to a pause, pulling into the pits after a stint on the C2s. He was running in the 1m22s throughout.
And there's just one hour left of day one! Last orders please, gentlemen.
Hamilton does six laps in a row in the high-1m18s to low-1m19s margin. There's been lost of race simulation running in the afternoon, but only he's been consistently in the 1m18s on consecutive efforts.
A tidier lap the next time around takes Verstappen to fourth place, courtesy of a 1m17.516s.
Verstappen does a personal best in the first sector on C3s, but dips his right wheel in the gravel at Turn 8 and is forced to back out.
Hamilton's 'proper go' didn't materialise that time by as he was five seconds down in the first sector. The next time around he comes up with a 1m17.963s, a second off his best.
Hamilton has seriously slowed down in S3, so presumably it's a cooldown lap and he's about to have another proper go.
He was off his personal best in S2, but a personal best S3 allows him to improve to a 1m16.976s overall. That's the C2 tyre still.
Hamilton and Magnussen have joined Kvyat on track, and the reigning champion has come up with a purple S1.
