Sebastian Vettel is hoping for more running in the afternoon session of the final pre-season test of 2012 after being hindered by problems in the morning.
The world champion, who got his first taste of the updated Red Bull RB8 today, managed only 15 laps in the morning, finishing at the bottom of the times.
Apart from a gearbox problem, Vettel also damaged his car's front wing when going off track, losing more track time because of that.
The German admitted it had not been a good morning.
"So far not so good," said Vettel of his day during the lunch break. "We would love to be on the circuit more, but this morning I had an issue.
"I went off track and broke the front wing and had to come in, and it took quite a while to get back out and just before lunch we suffered a problem with the gearbox so we have to fix it and get back out after lunch."
He admitted it was hard to judge the updates introduced yesterday because of the lack of running.
"It would not be fair to judge it because I haven't enough laps on the track yet with the new car. Yesterday was quite a decent step and a good day for Mark, so hopefully I get a few more laps in the afternoon."
And the world champion said he is not making any predictions about the pecking order for the Australian Grand Prix.
"Last year was too long ago, I can't remember. I think it is always a bit the same, you never know where you are until you get to Melbourne and everyone puts their pants down - and you can see what they have got and you show what you have got in qualifying.
"Until then we still will not know, but if we have a good Friday and the team is on top of Friday that will probably be the likely be the same on Saturday."
