One of the fascinating aspects of the car launches last week was that Mercedes have stuck with their design philosophy of last year and are pretty much unique in having a car with a long-wheelbase and low rake (angle from front to rear).

Last year, this gave them superb aerodynamic efficiency - and therefore stunning performance at high-speed tracks - but a restricted set-up window and relatively poor performance on low-speed, low-grip circuits such as Monaco and Singapore. It also took them a long time to understand how the car worked, technical director James Allison poetically describing its messages in the early part of last season as “a siren path that definitely dragged you on to the rocks. We had to ignore a lot of what we thought were the standard ways of race-engineering a car and go off in pretty much the opposite direction.”

Allison described the long wheelbase as “an asset” and said keeping it was “a no-brainer”. Mercedes hope to have combined its plus-points with removing its negatives.

And if you missed it earlier, here is the moment Fernando Alonso spun off the track and lost a wheel.

Fancy making a prediction for how many laps they will finish the day on?

DJ: McLaren need at least 50 laps in the afternoon session. There's a lot of good will for them (and Fernando) & they have to show something for it.

If you've just popped in during your lunch break to see what's been happening, here's a summary:

• Fernando Alonso and McLaren had a bad start to pre-season testing when the Spaniard had a spin when he lost a wheel just six laps into his running.
• The Spaniard returned to the circuit just before lunch.
• Daniel Ricciardo finished fastest with a 1:20.179 set on mediums
• Nico Hulkenberg completed the most laps of anyone with 73

It was a very good morning for Nico Hulkenberg and Renault as they finished with the most laps of anyone.

Kayleigh: Pretty solid first half of testing. Hoping for a good run from Alonso when he comes back from his dindins!

1) Hulkenberg 72

2) Hartley 72

3) Riccairdo, Raikkonen 60

4) Bottas 58

5) Stroll 46

6) Ericsson 41

7) Grosjean 32

8) Mazepin 22

9) Alonso 10

1) Ricciardo (Red Bull) 1:20.179 Medium

2) Bottas (Mercedes) 1:20.349 Medium

3) Raikkonen (Ferrari) 1:20.506 Soft

4) Hulkenberg (Renault) 1:20.547 Medium

5) Hartley (Toro Rosso) 1:22.371 Soft

6) Stroll (Williams) 1:22.452 Soft

7) Grosjean (Haas) 1:23.092 Medium

8) Alonso (McLaren) 1:24.202 Super soft

9) Ericsson (Sauber) 1:24.897 Medium

10) Mazepin (Force India) 1:25.628 Medium

Just a couple of minutes before lunch and Fernando Alonso heads back out to see what he can do in that time. He's onto nine laps for the morning.

Daniel Ricciardo sneaks in a quick lap before the break and goes quickest of all with 1:20.179.

Fernando Alonso takes it steady before heading back to base for a quick check over.

Meanwhile, Valtteri Bottas is back in P1 as he does a 1:20.349 on the medium compound, putting him two tenths clear of Kimi Raikkonen.

We've got six drivers on track as lunch approaches INCLUDING Fernando Alonso.

Woah, woah, woah! Put your sandwiches back in the Tupperware box because it's not eating time just yet.

The morning session has been extended by 10 minutes because of the delayed start to the day.
