time world champion Michael Schumacher took his Mercedes to the top of the time charts on the second day of testing Friday, a welcome boost with the new F1 season just four weeks away. Schumacher, who put in 112 laps, clocked a best time of 1min 20.352sec to edge out Ferrari's Felipe Massa who had been quickest on Thursday's opening day. “It clearly was a productive day, and obviously I am happy about that. We were focusing on long runs and being able to produce such a lot of mileage is positive in terms of reliability,” said the German.
