I have to say, it's quite interesting seeing the perceptions of Vettel change since his move to Ferrari. Last year we ran a poll similar to this and Vettel had a percentage similar to JB does now.
@GustavoEchenagucia: Yesterday Massa told us Williams is ticking a lot of boxes here in Barcelona, getting things done and focusing on aero tests on the car. I doubt we'll see a race simulation until next week.
@Senthil: I think the pecking order will remain similar to order in terms of the top three to last year (Mercedes - Renault - Ferrari), albeit with reduced gaps between all three. Where Honda fits in that equation is still the key question.
Mclaren has finally sent Button out on another lap. He completed just 12 laps this morning.
For those of you asking why Arrivabene would only want 'two' wins this seaosn, The Inside Line here explains why a moderate outlook is the best for all parties at Ferrari.
@Garry: That's all they've really been able to do this week, running an old car has limited the data it can take.
Button ticks over to lap 17.
As you can see, the order hasn't changed for a while. Only the lap counter changing at the time being. Buton has just trundled back into the pit lane.
@GustavoEchenagucia: Mercedes has still accumulated more laps. From what I've heard in the paddock, the engine Renault is running now is basically the one it plans to homologate next week - therefore its effectively its race engine for Australia. So anything extra Mercedes shows next week would be very telling.
I have an upgrade on why McLaren's running has been so limited.
Someone find me a Red Bull can.
So that means McLaren will be out again later this evening.
Ericsson moves up to fourth on the soft tyre, slotting in behind Hamilton. Verstappen has just clocked lap number 120.
@sat: Just over an hour left, yes. But every lap is crucial at this stage so McLaren will go out when it can - even if just for a lap.
@Sitank: McLaren is demonstrating exactly what testing is for. It knows it's not going to be in an ideal position in Melbourne - it's known that from the moment it signed with Honda for this year. The biggest benefit of Honda, and the main motivator for the switch, is that McLaren is no longer a customer outfit to another team on the grid. Ron Dennis said in the modern world of F1 a customer team could never win a championship and he's right.
With the personnel at the disposal of both teams, too, it won't be long until things get back on track.
@Bart: Honda cannot perfect its power unit if it does not have a car to put it in.
This whole 'sandbagging' thing is really overrated - especially during testing. There is no benefit for the teams holding back pace and no point just chasing headline times, they are all collecting more data than just "are we quick over one lap".
@Kriz: All sorts of reasons. You keep pushing the limits of the engine until you find something. There are also fuel loads to consider, aero tests, all sorts of things. Fans think the times are the only story here and frankly it gets repetitive making the same point over and over again.
@RacingFan: McLaren wouldn't have it any other way. It may have benefited from a customer car, like a McLaren B Team, but for the time being they are pooling all of their collective resources together.
@burnettbull: Homologate means the manufacturers have to present an engine to the FIA which is then effectively locked in for the season. Unlike last year, though, each team has the ability to use tokens to make upgrades in the seasons, though these are limited to 48% of the engine.
@Sulaiman: Massa set a time earlier today. Bottas has been doing pit stop practice and other little aero tests today, coming back into the garage every time.
We have another stoppage at the end of the pit lane.
It's Verstappen's Toro Rosso.
This red flag could is likely to take us to the final ten minutes. Fifteen minutes remain and everyone waits patiently to see if they can complete any final laps.
@Turboy: Usually a pit wall is fully functional, with every team member there, and a team will complete stints you would expect to see in a race, at consistent pace. You can tell when you're here which teams are doing a race sim from what's happening out there.
Green flag just as we hit the final minutes.
1800 at all the Barcelona tests.
Button one of the drivers to venture out for late lap.
@Max: I would imagine Mercedes is going to save some tokens for the season but it all depends how it feels with testing tomorrow. Teams are not privy to giving us journalists too much information on this sort of stuff.
Bottas finally completes a lap and relegates Button to last.
Chequered flag is out! Report and reaction all to come on ESPNF1.
