Lewis Hamilton says that he felt positive from MP4-27 and he is confident McLaren will set top into the 2012 with aggressive machine.
"Today was all about testing set-up," he said after finishing day two with a best time of 1:24.111.
"It was a good day: we learned quite a lot and improved a few things. We didn't get a lot of mileage, as we had a lot of downtime inbetween changes.
"Our car feels better set-up wise, we still haven't added the new aero package - so I think we'll get a better picture of what the car will be like in Australia over the next two days. But I definitely feel like we have a competitive car."
"This year's winter testing has been way better than last year. I've not had any problems, we've ironed out a lot of issues and I feel very comfortable. I'm fit and ready for Melbourne," he added.
