Rosberg tests at Sepang

With the first two days of the Williams teams Sepang test sunny and hot the third would see the team greeted by a track that was soaked by an overnight shower. This would limit the teams track time in the morning but it would clear up for a short period in the afternoon only to be followed by further rain.

Replacing Alex Wurz for today's test was team-mate Nico Rosberg. Nico would focus on further tests of the FW29 including brakes and cooling. He would finish sixth in the times at the end of the day. The test was only meant to be for three days but with the conditions on the final day limiting dry running the team decided to extend the test for another day.

AT&T Williams Race Team Manager Tim Newton commented: “It rained overnight so the track was fairly damp this morning, the cloud started to clear but it wasn’t enough to dry out the track before the session started. As such, Nico was able to trial the car in damp conditions, which helped give us some important data for the race.

While acclimatising to the extreme humidity on his first day of testing, Nico concentrated on brake, aero and cooling tests as well as carrying out systems checks. We were making good progress until the rain came pouring down at 3.30pm which forced us to end the session early. Due to the shortened running time, we will test for an additional day tomorrow.”
