Minor issues hamper Rosberg's progress
27 February 2014 – Nico Rosberg lamented a few problems which hindered his progress on the first day of the third test in Bahrain.
Rosberg, who set the pace during last week's second test, was fourth quickest as he focused on long runs during the afternoon session.
The German driver completed 89 laps overall but his running came to an end an hour earlier than scheduled after Mercedes discovered problems with the W05.
"That was not a fantastic day for us," he said of his running, which included a spin under braking at Turn 10.
"We tried some new parts on the car and you find out a lot through doing that. But unfortunately we did not only discover good things today. I managed to do a couple of good laps before lunch but in the afternoon we had a few small problems which ended my running a bit earlier than planned."
Rosberg was nonetheless optimistic about Mercedes's progress, with just three days of testing remaining prior to next month's season-opening Australian Grand Prix.
"This shows that we are pushing everything to the limit and we still have a massive challenge in front of us during the last three days of testing," he added.
"We need to maximise our time here to be prepared for Melbourne. But after a difficult day overall we are on the right path."
