The seven-time World Champion clocked a 1:21.249 at the Spanish circuit, which was the fastest time seen at the track this year.It was an encouraging performance from Schumacher, who confirmed that the W02 in action at Barcelona on Friday will be the W02 that his team takes to the season-opening Australian GP.
"We have been developing the car step-by-step this week with new parts arriving each day," the German revealed.
"So our focus today has been on understanding how to get the best from the car now that it is pretty much in its final configuration for the first time.
"The car has behaved as we expected and it's been a very productive day.
"We completed our programme and I should also be able to get some experience of the expected wet conditions tomorrow."
With the rain expected on Saturday, Schumacher's team-mate Nico Rosberg put in a few hours in the dry on Friday.
And the younger German was not that far off his team-mate's pace, finishing 0.539s down, taking third place behind Ferrari's Fernando Alonso.
"First of all, it's super that I was able to do some laps today, given the forecast for tomorrow," said Rosberg.
"It was a good few laps, and obviously now that we have most of the developments for the car, it was handling much better and I had a good feeling.
"So I'm pretty pleased with the situation and would like to thank the whole team for getting everything onto the car that we wanted. We've made good progress over the winter."
