Ross Brawn believes that Mercedes W03 only needs to set-up and not about the miss-design.Untill the second series in Malaysian Grand Prix,Both Shumacher and Rosberg has scored only one point this season,despite having had a car that could match the speed of McLaren.
From the results of Australian and Malysian Grand Prix could be concluded that the tyres is a major problem.In Australia, Mercedes suffered a high degradation caused by the overheating of tyres, while in Malaysia its bid to keep the rubber backfired after the cooler conditions in the race means that the driver can not be hot in their rubber.
Brawn spoke at the Brackley factory on Thursday, insisting that nothing is wrong with the car W03 2012,said Brawn “I think we can go a long way [to solving the problems] with set-up,” said Brawn, who revealed how narrow the temperature operating window is.
He continued,”Obviously we are looking as to how you manage the situation, but in Malaysia it was interesting – because the car that won and the car that was second, we know from Friday practice were very, very hard on the tyres. And it turned around for them in the race.
“But you are talking about 15-20 degrees either side of the optimum being quite critical…it is quite a sensitive window. And it is something that the drivers can operate in, because if they get into that window then they feel the tyre getting a little bit overstressed, or if they ease back they can manage it, but outside of that it is quite difficult for them.”
Brawn said that he was ‘very confident’ that Mercedes has made good progress with the car this year, although it has not yielded on Sunday afternoon.
“On Fridays we run the car in race trim and we are quite diligent in running the right kind of fuel loads to represent race conditions. And we think other people don’t run more fuel than us, because it would be difficult for them to run more fuel than us. So if you look at the comparative lap times, we think we are okay.”
But Brawn does concede, however, that Mercedes may need to look at ways of widening the performance window that the car operates in.”We had one race which by our own admission we didn’t do a good enough job in [in Melbourne]. And one race which was an unusual set of circumstances – and a couple of things we did to try and respond from Melbourne went the other way for what we faced in the race in Malaysia. So I am still pretty confident.
“We have not had a clean weekend where we can make a judgement, but I have to say that cars have to be able to cope with a wide range of conditions and, if there is something we have to look at, it is broadening the ideal conditions that the car operates in.
“You also have this dilemma: do you create a situation where you have ultimate performance but it is a bit peaky, or do you come back a little bit from that and have a broader base? We are conscious of perhaps needing to broaden the base, but that is stuff that I think we can do. We can make our decisions on what we want to create.
He concluded,”But I would like to see a couple of clean weekends – with relative consistent conditions over a weekend and see where that puts us. I think there have been a few teams that are out of position, and maybe we are the most extreme, in terms of not quite coming together in the way you would expect. I think it is all of us getting used to this new family of compounds that we have got from Pirelli.”
