Michael Schumacher pleased with new Mercedes F1 car potential

The German, who had already driven the car during a shakedown and during Sunday's private test in Barcelona, managed 51 laps on his way to the sixth quickest time of the day.

Although Schumacher's session was shortened due to a hydraulic problem, the seven-time champion was pleased with how the new car handles.

"Reasonably positive," said Schumacher of his day. "It is the fourth day we are in the car and it's the first time we had a little issue with the hydraulics.

"It has good potential. I had a good feeling inside the car. It's difficult to say what that feeling is worth because of the rule changes, but the potential is good."

He refused to judge the pace of the car compared to the opposition, however.

"I don't want to be too precise right now, because I have not been able to overlay our running with the other guys and that is the important matter that can give me a direction, or at least confirm the feeling that I have."

Schumacher also said he had no concerns about the looks of the new car as long as it's quick.

"For us it's very transparent. The main point is that the aero numbers are good and there are different ways of interpreting the rules. We'll find out what is the better way. For us it's not really anything special. The most important thing is what we see on the clock and that is what I'm looking at."

And the Mercedes driver, whose contract with the team expires this year, said he is not thinking about his plans at the moment.

"There's no reason to make any statements or comments about my future. I will make a decision when it's the right time."
