Michael completed 38 laps of the 4.67km circuit during the two practice sessions in preparation for the German Grand Prix.
"Overall, the session went ok, even though we didn't do too much running in the first session because the conditions were a bit too inconsistent," said Michael after posting P4 and P23 lap times on Friday. "I think that qualifying will probably be wet tomorrow, so today's weather was useful in that respect. Now we need to do more work on the computer to tease out the insights we weren't able to get from our track running."
Late in the afternoon, Michael spun off track during a heavy downpour. "The way I ended the second session was obviously not part of the plan and I'm sorry that my mistake has given my guys even more work to do this evening," said Michael. "I simply slid off track because I lost a little concentration: we were talking on the radio and I was altering some settings at the same time. But that's all part of the game."
