F1 journalist Dan Knutson: It pays to wait The fans waiting outside the McLaren hospitality unit got a double treat. Not only did Fernando Alonso emerge, but also rally legend Carlos Sainz.

Kayleigh: I'd go for something like "Best Team" cause even when we're bad, everyone would be calling us the best. Plus I love an oxymoron. The livery would be whatever colour my hair is that month, so could change a lot. If the car was made right now, it'd be half blue/half green.

I like the thinking, although if I did the same my car's livery wouldn't change for 20 years. The last time I had a different hairstyle was in 1998.

Fernando Alonso is back in the car and ready to go...

You've got nine minutes before we DROP EVERYTHING for lunch.

F1 journalist Dan Knutson in Barcelona: The wheel(s) came of McLaren’s first day of testing with new engine partner Renault. There was a wheel nut failure on Fernando Alonso’s car, and the team will have him back out on the track later today. While the stoppage was reminiscent of the unreliable Honda days, the team remains upbeat.

“There is no drama,” McLaren’s Zak Brown said when he chatted with the media in McLaren’s hospitality unit.

“Everyone is quite relaxed and getting on with it. It is quite an easy fix that we are doing to get back out on track. This team is used to public pressure and having eyes on us. We enjoy that. We like to step up to the plate, and we thrive on the opportunity. So we are not in any added pressure that we do not already put on ourselves.”

Lee Davidson: I would move my Sim-Racing team @EpicRacing1, external into the real world, along with its lovely yellow livery.

Kimi Raikkonen moves back into P1 just before lunch as he does a 1:20.506. Nico Hulkenberg (1:20.547) is second.

Both drivers are back in the pits with Daniel Ricciardo and Brendon Hartley the only drivers on the track.

Here's a couple of shots of some of the cars.

Luke Severn: So the question is will @McLarenF1, external complete more than the 29 laps they did last year

23 to go with just under five and half hours remaining. Surely...

McLaren say a "wheel nut problem" caused Alonso's off this morning. No further elucidation supplied. They say he should be back out "in 15 mins or so".

Speaking of Fernando Alonso, Andrew Benson has an update on his and McLaren's situation...

F1 journalist Dan Knutson in Barcelona: McLaren is located at the very far end of the paddock. The Spanish fans are hanging around outside the hospitality unit hoping to get a glimpse of their hero Fernando Alonso.

Here's a reminder of how the first day of testing finished last year:

1 Lewis Hamilton (GB) Mercedes 1:21.765* (73 laps)

2 Sebastian Vettel (Ger) Ferrari 1:21.878 (128)

3 Felipe Massa (Brz) Williams 1:22.076* (103)

4 Kevin Magnussen (Den) Haas 1:22.894* (51)

5 Daniel Ricciardo (Aus) Red Bull 1:22.926* (50)

6 Valtteri Bottas (Fin) Mercedes 1:23.169* (79)

7 Sergio Perez (Mex) Force India 1:23.709* (39)

8 Carlos Sainz (Spa) Toro Rosso 1:24.494 (51)

9 Nico Hulkenberg (Ger) Renault 1:24.784 (57)

10 Fernando Alonso (Spa) McLaren 1:24.852* (29)

11 Marcus Ericsson (Swe) Sauber 1:26.841 (72)

* time set on soft tyres; all others set on medium tyres

Andrew Evans: Vulcan racing British racing green and grey. Proper racing green too, not that silly metallic version.

Casey Jennett: If i had an F1 team, i would call it Pacifica Racing, and i would have an all electric blue car withwhite highlighting. The reasoning for both would be because it is based on my guitar

What would your F1 team be called and how would the car look? Let us know via #bbcf1

Nico Hulkenberg has also brought up his half century of laps. He's onto 53 now.

1) Hulkenberg - 53 laps

2) Hartley - 50

3) Raikkonen, Bottas - 43

4) Stroll - 34

5) Ericsson - 32

6) Ricciardo - 27

7) Grosjean - 18

8) Mazepin - 15

9) Alonso - 6

That didn't last long.

Nico Hulkenberg swiftly usurps Kimi Raikkonen at the top as he does a 1:20.863.

Kimi Raikkonen is the new leader as we approach lunchtime. The Finn does a 1:20.970, putting him three tenths clear of Nico Hulkenberg, who is currently second quickest.

With Force India suggesting a team name change is strong possibility before the start of the season we would like to know:

If you created an F1 team what would you call it and why? What would be your colour scheme?

If you are feeling creative, feel free to pen your design on paper and send it in to #bbcf1

Force India are arguably F1’s best team in terms of bang for buck but they know they are up against it this year in terms of trying to hold on to fourth place.

But that doesn’t mean they are not going to go for it. Chief operating officer Otmar Szafnauer said: “It is going to be hard for us to maintain where we were last year. Renault have added loads of people and McLaren have changed power-train so they say they are going to be better. Williams have a Paddy Lowe car and hired a chief aerodynamicist from Ferrari. They have more resource than us and bigger facilities. So it will be hard to maintain fourth but that’s our target and we think we can do it.”

1) Hulkenberg (Renault) - 1:21.326 - Medium

2) Bottas (Mercdes) 1:21.843 - Medium

3) Raikkonen (Ferrari) - 1:21.986 - Medium

4) Grosjean (Haas) - 1:23.092 - Medium

5) Ricciardo (Red Bull) - 1:23.221 - Medium
