If anything Lotus and Ferrari were the teams who had something in hand with rising temps.FI and TR were the ones who had a handle on those tyres before the changes so it seems reasonable these two will still struggle with the new tyres .
Mercedes is going to struggle .They were just hopeless last year and I se not many reasons why this should suddenly change ,especially considering they will be the sole team without ANY mileage with the new tyres going into the race weekend .
If I were MGP i would certainly try to put one of my drivers into a seat during that test ...Sauber could be a well placed prospect ...powertrain deal for 2014 + a guest drive for Nico and Lewis in the Sauber,anyone? i heard Monisha needs all the money and incentives she can get these days...
RedBull seems to be the team that had difficulty with tyre degradation at the start of the season but it looks like they have
found something to mellow that characteristic without slowing them down overall.
