@RahulJangam: I think that is a realistic estimation. Certainly for the start of the year it will be about how much the others have caught up with Mercedes, not about how much further ahead they are.
@Marty: You'll be disappointed I fear.
Now Button gets out on track for the first lap of the day in the McLaren. So we've now seen all eight cars here in Jerez on track.
@V8Unleashed: I think we can expect a stronger day today.
Kvyat and Ericsson are the only two drivers on track at the moment.
@DuncanSant: Neither is unusual for a test day. Mercedes have been going to the end of the pit lane and Hamilton has been revving the car hard while stationary before doing a practice start. It sounds a bit like they are trying to break it, which probably isn't far from the truth. A lot of testing is about finding weak points before the first race. Because he has been coming straight back into the pits on every lap he has not set a time.
Kvyat hasn't come back to the pits so it appears the Red Bull has stopped somewhere on track.
I've just been up on the media centre roof and it looks like the Red Bull is in the gravel at Turn 8.
It's too far away to see if there is any damage. A recovery truck has been dispatched to bring the RB11 back.
@kaustav: I would say the McLaren is the most drastic change overall, but possibly not the most impressive nose. Talking to a few people, that award appears to have gone to Red Bull and Mercedes for their super-short efforts. The Red Bull one was apparently particularly tricky to crash test and they had some back up ideas in case it failed.
My mistake, that's actually Turn 9 where he has found the gravel.
Turn 9 is the same corner Felipe Nasr spun off yesterday morning when it was damp. It's in the shade down there so possibly a bit more slippery than elsewhere on the circuit.
@SunnyPerth: Not a Daniel Ricciardo fan by any chance are you? ;)
@mfbull: Actually McLaren are pretty happy. I haven't seen it in the slow stuff but Alonso pushed a couple of times into Turn 1 and the team reported back that it was sticking quite nicely. The slow speed corners are less dependent on aero and more about power delivery and driveability - considering getting the engine started was an achievement yesterday, there is probably plenty of smoothing of the power and torque curves to be done before Melbourne. The chassis and aero, however, is not providing to many nasty surprises at this early stage.
@barkun: I suppose Kvyat's little off is proof that you are better off in the garage than in the gravel. But it does seem a bit odd.
@kaustav: A little bit, yes. It's still damp out there but the good news is that the sun is out and drying the track.
The green light is back on. Verstappen is quick to head back out and now he's been joined by Ericsson.
@mfbull: Very hard to say, but at this stage of the pre-season you can't rule out a car issue - or lumpy torque delivery or braking instability. Kvyat looked like he lost it under braking and went straight on into the gravel. He didn't look close to the barriers at the end of the gravel trap, so hopefully it wasn't too bad.
