After an inconclusive and perhaps even worrying performance at Jerez, the faces in the McLaren garage are looking happier as the second group test progresses in Barcelona.Lewis Hamilton said: "We're in a much better position than we were this time in 2011, and also better than we were two weeks ago in Jerez."We have learned a lot; the car is much better balanced now. I can say that we have a stronger base than last year," added the 2008 World champion.According to the Mirror newspaper, Hamilton's team mate Jenson Button agreed: "There are no excuses this year. I feel we have everything."We're on target. There's nothing to say we're one and a half seconds quicker than anyone, but then there's also nothing to say we're not fast," he said.FERRARI IN TROUBLE?Red Bull's reigning back to back world champion Sebastian Vettel is quoted by the Telegraph as saying he thinks McLaren will be "strong straight from the beginning of the season".Mercedes' team boss Ross Brawn: "Red Bull will have a strong car again, and so will McLaren. Ferrari seem to be having a few difficulties."Red Bull reserve Sebastien Buemi, having watched from a trackside position, said Fernando Alonso looked uncomfortable with the handling of the F2012.Alonso said: "I think we are probably not the quickest today, but neither are we the slowest."At the moment we are not where we want to be, nor where we want to be in Australia, but I remain optimistic. We just have to hope that we have completed this learning process we are going through with a very complex car by the time the season starts," he said.
