@burnettbull: Obviously this is entirely subjective, but I would say: 1. Honda, 2. Ferrari, 3. Renault, 4. Mercedes
@H278: He's done an entire race sim, which was interrupted by Carlos Sainz Jr beaching himself in the gravel. But that shouldn't deter from a very impressive effort from Mercedes this afternoon. 77 laps and counting for the reigning world champion.
The Renault in the Caterham used to be my favourite because it had a weird high pitch wail in the exhaust note. It was particularly noticeable at Monaco between the buildings and going up the hill from St Devote to Beau Rivage - it sounded a but like some one had let a (quiet) V12 out on the track. I never found out why it did it... probably because it was broken
Sadly the Ferrari no longer makes little "pow" noises on downshifts. But the overall exhaust note sounded nicer than last year when I was in Jerez.
@mfbull: I think that's what I mean
@mfbull: No. I once asked at McLaren and they wouldn't even show me inside.
Williams has been pretty quiet today, all things considered, but Massa has just gone purple in the first sector and jumped to fourth overall on the soft tyre.
@elmezquita: A lot of people think they are noisier but there is no reason. They might be running the engines about 500rpm higher than last year, but they are still around 10,000rpm and not near the 15,000rpm limit - which would be inefficient due to friction. In Jerez, the engines sounded louder on the pit straight, but it is a close pit lane there between the pit building and the main grandstand. When I watched from Turn 2 (up on a slight hill) there was no obvious difference in volume.
@mfbull: No, I was invited to the factory but not as far as the sim. McLaren are very private about theirs, other teams less so.
@MDRivazza: A positive day considering the problems with the MGU-K. But it's still something of a lost day given that the a fix for yesterday's issue can only be delivered on Saturday.
@Rahul8145: I think they will be both quite evenly matched, but Raikkonen hasn't quite been the same since the change in tyre construction midway through 2013. I think this will be his last season if the results don't come, whereas Seb is in it for the long haul.
@Scuderia: They split today's running to make up for lost time yesterday when Hamilton had a fever and couldn't run. Rosberg is also struggling with a neck strain, so it made sense to split today as well as keeping it fair. It's entirely okay by the rules, they can have as many drivers as they want in one day of testing.
@Scuderia: That's right, only one car per team.
@burnettbull: It's a cost thing. You need more people to run a second car and it was decided when testing was reduced to limit it to one. For the teams it's not so bad as they can focus their attention on one car rather than two and at this stage second chassis are often still being fabricated along with lots of other parts.
@Scuderia: It looks like Caterham will not return to F1. Marussia may well be back in Australia though.
Red flag - Marcus Ericsson has stopped his Sauber at the end of the pit lane.
Ericsson's car doesn't take long to remove and the green flags are back out as the clock ticks into the final half hour of day two.
@mfbull: It changes from team to team. They typically produce about four or five chassis per season, sometimes more if a driver has an accident. At the Australian Grand Prix last year the following drivers were using chassis No. 1: Hamilton, Maldonado, Magnussen, Gutierrez, Bottas, Bianchi and Ericsson. Some teams had three or even four chassis by the first race last year. But if a chassis works and is not cracked then there is no reason not to use it
@Scuderia: Only if there are major changes to the way the sport is run, such as customer cars or, preferably, a fairer distribution of prize money.
