Nico Rosberg completed the third day of testing for the MERCEDES GP PETRONAS team at the Circuit de Catalunya in Barcelona today to bring his pre-season testing programme to its conclusion.

Nico spent the morning working on qualifying simulations and developing the car set-up before completing a race simulation exercise in the afternoon. Despite intermittent rain showers in the late morning and early afternoon, Nico was able to complete almost 600kms over 128 laps as he set the fastest time of the day, a 1:20.686, during the driest period this morning.

Michael Schumacher will take over the MGP W01 tomorrow for the fourth and final day of the test.

Nico Rosberg: "We had a good day today and made some significant progress in terms of set-up which was nice to see. We hadn't got the most out of the car in terms of performance over the last couple of days, but we made a step in the right direction today. We went through some big changes this morning step by step and found some good improvements. The longer runs this afternoon were interesting. We learnt a lot as there were other cars running similar programmes at the same time so we were able to do some comparisons. There is still plenty of room to improve but overall we're looking in pretty good shape."
